Finding the best cat water fountain starts with a stubborn feline instinct: cats evolved to distrust still water, so plenty of them drink far less from a bowl than their kidneys would like. We checked seven of the most popular fountains against veterinary hydration guidance from the Cornell Feline Health Center and the AAFP/ISFM environmental-needs framework, independent hands-on testing from cat-focused reviewers, and live Amazon listings re-verified on 16 September 2026 — so the capacities, materials, motor types and prices below are current rather than recycled.

- The Bottom Line
How We Chose These Fountains
We start from the veterinary consensus on feline hydration, then pressure-test the marketing. Cornell’s Feline Health Center sets the baseline: a cat needs roughly four ounces of water per five pounds of lean body weight each day, and Cornell notes plainly that “some cats increase their intake of water when provided with water fountains, but individual preferences among cats for these varies.” The AAFP/ISFM Environmental Needs Guidelines — organized around five primary concepts for a healthy feline environment — treat water availability as part of that framework. Preventive Vet, written and reviewed by practising veterinarians, puts the everyday target at 3.5–4.5 ounces per five pounds per day and warns that water bowls should be grade-304 (18/8) stainless rather than cheap “pet use” steel.
On top of that guidance we cross-checked independent hands-on testing — the cat-tester roundups at Hepper and Cats.com, plus The Spruce Pets’ real-cat testing and the Forbes Vetted fountain review — then re-verified every one of the seven listings on Amazon in September 2026 for brand, stock and price. Read our full process on how we test and choose products.
Sourcing transparency: we are not a laboratory and we do not claim to have measured noise in decibels, water temperature or filtration efficiency ourselves. What is first-hand here is the live listing data — capacity, material, power type, price, stock and category rank, all read from the current Amazon listings. What is aggregated is the hands-on testing published by the named independent reviewers, and the hydration numbers come from the veterinary sources cited above. Any figure we could not source or verify is not on this page.
How to Choose a Cat Water Fountain That Your Cat Will Actually Use
Why Cats Prefer Running Water
Your cat’s ancestors sourced water from flowing streams, and that instinct survived domestication intact. Standing water in a bowl collects dust, warms to room temperature, and grows a slim biofilm within hours, all of which a sensitive nose detects long before you do. A good fountain solves the problem mechanically: constant circulation keeps the water moving, filtration strips hair and debris, and the visible flow invites cautious drinkers to approach. Cornell’s Feline Health Center lists chronic kidney disease, diabetes, hyperthyroidism, vomiting and diarrhoea among the conditions that cause increased water loss, which is why encouraging everyday intake is preventive care rather than a luxury.
Material Matters: Stainless, Ceramic, or Plastic
Stainless steel is the easiest material to keep genuinely clean because it resists scratches that harbor slime, and most steel bowls and towers drop straight into the dishwasher. Preventive Vet’s bowl guide recommends steel labelled grade 304 or 18/8 and notes that “pet use” stainless is often a lower grade; it also flags the historical Petco recall of imported bowls found to contain trace radioactive cobalt-60 as the reason sourcing matters. Ceramic shares the non-porous virtues and looks handsome on a counter, but it is heavier, pricier, and chips or shatters when knocked. Plastic wins on price and weight, yet its surface micro-scratches over time and can provoke feline chin acne in sensitive cats. Whatever you choose, the practical test is disassembly: a fountain with five parts you can strip and rinse weekly beats a fifteen-piece sculpture that never gets cleaned properly.
Capacity: Sizing the Tank to Your Household
Cornell puts a cat’s daily target at about four ounces of water per five pounds of lean body weight, which lands most indoor cats somewhere around four to eight ounces a day; Preventive Vet’s range runs 3.5–4.5 ounces per five pounds. A two-litre tank therefore stretches several days for one cat but barely a day for three. Multi-pet homes that share the fountain with a dog should jump straight to large-capacity designs like the SohoTeco 270-ounce basin below. Small-capacity fountains remain worthwhile for apartments and single-cat households because fresher water more often beats more water, but expect to top them up every two or three days.
Pumps, Noise, and Power Options
The pump is both the heart and the usual point of failure in any fountain. Traditional wired submersible pumps hum quietly at first and grow louder as debris loads up, which is why regular rinsing matters as much for your ears as for hygiene. Newer wireless designs, like the magnetic-induction pump in the PETKIT Solo 2 and the rechargeable battery in the PETLIBRO Dockstream, run nearly silent and keep working through power cuts. Look for auto shut-off protection that kills the pump when the water runs low, since dry-running burnout is the single most common way fountains die young.
Filters and Cleaning Cadence
Most fountains pass water through a carbon-and-mesh cartridge that catches hair, kibble dust, and off-flavours, and manufacturers recommend swapping it every two to four weeks. Budget for that consumable from day one, because subscription costs can quietly double a cheap fountain’s lifetime price. Beyond filters, give the whole unit a proper scrub weekly: hot water, a bottle brush for the bowl, and a monthly descaling soak in diluted vinegar to dissolve mineral crust from hard-water homes. Dishwasher-safe components, found on the SohoTeco, Wonder Creature, and Catit picks below, turn the chore into a five-second load-and-shut routine.
Live Spec Comparison: What Each Listing Actually Says (16 September 2026)
This table is built from the current Amazon listings rather than copied from another roundup. The last column is the honesty check: several listings publish a claimed noise figure but no capacity-and-flow data, and no manufacturer publishes a measured filtration result — so treat every “quiet” badge as a seller claim, not a measurement.
| Rank | Pick | Listed capacity | Body material | Power | Live price | Listing’s own claim |
|---|---|---|---|---|---|---|
| 🥇 | PETKIT Eversweet Solo 2 | 70 oz / 2 L | Plastic tank, steel tray | Wireless induction pump | $44.99 | No dB figure published |
| 🥈 | PETLIBRO Dockstream Cordless | 84 oz / 2.5 L | Stainless tray | 5,000 mAh rechargeable | $62.99 | Claims a month per charge |
| 🥉 | SohoTeco 2-Gallon Stainless | 270 oz / 8 L | 304 stainless steel | Wired pump | $55.99 | Claims <25 dB |
| ⭐ | GIOTOHUN 108 oz | 108 oz / 3.2 L | SUS 304 stainless | Wired pump, LED window | $49.99 | Claims “4-stage filtration” |
| ⭐ | Wonder Creature | 81 oz / 2.4 L | Steel lid, plastic tank | Wired pump, LED alert | $17.99 | No dB figure published |
| ⭐ | Catit LED Flower Fountain | 100 oz / 3 L | Plastic (BPA-free) | Wired pump, 3 flows | $34.99 | Claims “triple action” filter |
| 💰 | Veken 108 oz | 108 oz / 3.2 L | 304 stainless steel | Wired suspended pump | $27.99 | Claims a 25 dB pump |
What You Get as You Spend More — and Where Paying More Stops Helping
Across the seven listings we verified, the money buys three distinct things, and only the first two matter.
- Under about $25 — plastic and a basic pump. The Catit and Wonder Creature tier gets a working circulating fountain, a low-water LED and a plastic body. You will clean it more often and replace the pump sooner, but the water still moves and the cat still drinks.
- About $25–$55 — stainless surfaces, bigger tanks, quieter motors. This is where the Veken, GIOTOHUN and SohoTeco picks sit, and it is the sensible ceiling for most homes: 304 stainless in the wetted path, three litres or more of capacity, and a suspended or brushless pump that stays quiet.
- Above roughly $60 — you are buying convenience, not hydration. The PETLIBRO Dockstream Cordless is the clearest example: its premium is a 5,000 mAh battery that frees the fountain from a wall outlet, not better water. Nothing in veterinary guidance or in the independent testing we read shows a cat drinks more from a $63 fountain than from a $28 one.
So the specific stopping point is this: once you are at three litres of grade-304 stainless with a suspended pump, paying more buys placement freedom and app features, not health. Spend the difference on filters instead — you will change a cartridge about every two to four weeks, and that consumable is the real lifetime cost.
Where We Disagree With Other Reviewers
Three named reviewers lead this category, and our ranking differs from all three on purpose.
- Cats.com names the PETLIBRO Dockstream Battery-Operated fountain its overall best after hands-on testing. We rank a PETLIBRO model second, not first, because the cordless Dockstream costs about $63 and its advantage is battery convenience; the PETKIT Solo 2 delivers the same near-silent, cord-free pump for around $18 less.
- Hepper crowns the Torus filtered bowl — a passive refilling bowl with no pump at all. It is a legitimate pick for a frightened kitten, but it holds just 68 ounces and the water only moves when the level drops, so it does not deliver the continuous circulation that gives a fountain its point. We would use it alongside a fountain, not instead of one.
- Forbes Vetted also leads with the PETLIBRO Dockstream Cordless fountain. We agree it is excellent; we simply do not think “best overall” should default to the most expensive pick when a quieter, cheaper cordless option exists.
Where we all agree: a fountain is worth owning, stainless beats plastic for the wetted parts, and no fountain replaces fresh water and a weekly scrub.
The Failure Modes Nobody Lists
Read enough owner reviews and the same complaints recur regardless of brand. These are the patterns worth knowing before you buy:
- Pump death by dry-running. The most common one-star theme is a pump that burns out after the reservoir ran low — which is why auto shut-off and a visible low-water window matter more than any smart feature.
- Hard-water crust on the pump impeller. In hard-water homes, mineral scale seizes the impeller and the fountain goes quiet, then loud, then dead. A monthly vinegar soak prevents it.
- Biofilm in plastic seams. All-plastic fountains grow a slime ring in the corners that owners miss; stainless or removable trays cut the failure rate, not the cleaning frequency.
- Filter cost creep. A cheap fountain with a proprietary cartridge can cost more per year in filters than the fountain itself.
- Chewed cords. Traditional wired pumps put a live cord at exactly the height a bored cat explores — the single clearest argument for a cordless or induction model.
- Battery forgetfulness. Cordless models fail the other way: a flat battery means a silent, still fountain until you notice.
🥇 1. PETKIT Eversweet Solo 2 Cat Water Fountain (Best Overall Cat Water Fountain)
For the least glamorous reason possible, this is our top pick: it is the easiest fountain here to take apart and clean. Only five main parts come apart in seconds, and the tank lifts off a magnetic induction charging base so there is no cord dangling into the water at all. The wireless pump is nearly silent, and an auto shut-off protects it from burning out when the level drops — the failure mode our owner-review scan found most often across the whole category. The companion app tracks filter life and sets cleaning and refill reminders, which busy households genuinely rely on. At 70 ounces the bubbler-style tank suits cats and small dogs, though very thirsty crews will refill more often than they would like. It is the rare smart fountain where the smarts serve hygiene rather than gimmicks.
What We Like
- Five-part teardown makes weekly cleaning genuinely painless
- Wireless induction pump is near-silent and cord-free
- Auto shut-off plus app reminders protect pump and schedule maintenance
What Could Be Better
- No USB wall adapter included despite the app-centric design
- 2 L tank means frequent refills for multi-pet homes
Best For: Single-cat and two-cat homes who want the cleanest, quietest smart fountain without cord clutter.
Flaws but not dealbreakers: It ships without its own 5V wall adapter, so raid your drawer for a spare phone charger before setup. Customer service experiences with PETKIT run mixed if a pump fails out of warranty, and the modest tank asks multi-pet households to refill every day or two.
Skip it if: you have three or more cats, or a dog that shares the bowl — the 2 L tank will have you refilling twice a day, and the SohoTeco pick below is the better answer.
🥈 2. PETLIBRO Dockstream Cordless Pet Water Fountain (Best Cordless Smart Fountain)
Forbes Vetted crowns this dockless design its best overall fountain, and the reason is freedom: a 5,000 mAh rechargeable battery drives the pump, so there is no power cord for kittens to chew or outlets dictating placement. You can park it across the apartment from any socket, tuck it into a hallway niche, or move it seasonally, and the stainless steel tray lifts out for washing. The SilentFlow pump keeps noise to a murmur even on battery, and the listing rates roughly a month of runtime per charge in normal duty cycles. The 84-ounce tank splits the difference between compact and capacious nicely for one to two cats. Within PETLIBRO’s wider Dockstream family, app-connected versions log daily drinking totals, useful for spotting health changes early. For renters and anyone whose floorplan fights their furniture, this cordless fountain is the obvious pick.
What We Like
- True battery operation frees placement from wall outlets
- Whisper-quiet pump with about a month per charge
- Removable stainless tray simplifies scrubbing
What Could Be Better
- Battery needs periodic recharging, another chore to remember
- Buy-box pricing swings widely between colours and sellers
Best For: Apartments, renters, and cord-hating cat parents who want smart features without cable clutter.
Flaws but not dealbreakers: You are signing up for a recharge cycle roughly monthly, and forgetting means a silent, dry fountain until you notice. The listing sometimes routes shoppers through additional buying options with varying prices, so compare sellers before checkout, and heavy multi-pet homes may want the larger Dockstream 2 sibling instead.
Skip it if: you want the cheapest route to moving water, or you know you will not maintain a charging habit — a corded stainless model does the same job for less.
🥉 3. SohoTeco 8L / 270oz 2-Gallon Stainless Steel Fountain (Best for Multi-Pet Homes)
When the household includes big dogs, multiple cats, or both, most cat fountains simply run dry. The SohoTeco is the opposite philosophy: an eight-litre (270-ounce, two-gallon) 304 stainless reservoir whose flowing-water faucet keeps a large volume circulating. That is more than three times the capacity of our top pick, which is the entire point — a three-cat household drinking to Cornell’s four-ounces-per-five-pounds guideline can go days between refills instead of hours. Nearly everything that touches water is stainless steel, the water-level window lets you check the tank without opening the lid, and the listing bundles six replacement filters. The heavier steel body resists the tip-overs that knock over lightweight plastic fountains, and the pump is rated under 25 dB. This is old-school engineering rather than smart tech: no app, no battery, just capacity and clean materials.
What We Like
- 270 oz / 8 L capacity serves dogs and multiple cats at once
- 304 stainless steel body with a visible water-level window
- Six replacement filters included; listed pump rating under 25 dB
What Could Be Better
- Large footprint needs real counter or floor space
- Wired pump still needs an outlet, and heavy tanks are awkward to lift when full
Best For: Multi-pet and large-dog homes that need serious capacity and all-stainless hygiene.
Flaws but not dealbreakers: A full two-gallon tank weighs about fifteen pounds, so plan the refill spot before you fill it. It is also a plainer-looking fountain than the smart picks — no app, no LED glow — and like every wired model here it puts a cord within chewing range unless you route it carefully.
Skip it if: you have a single cat in a small flat — an eight-litre reservoir is more water than one cat will drink before it needs refreshing.
⭐ 4. GIOTOHUN Cat Water Fountain Stainless Steel 108oz (Best Faucet-Style Stream)
Some cats ignore every bowl and hold out for the bathroom tap, and this is the fountain built for them. The GIOTOHUN’s arcing spout reproduces a falling faucet stream closely enough to finally convert tap addicts, and the listing sells the faucet-running-water and fountain modes as a pair. It is also quiet for a wired fountain, with an LED-lit translucent ring doubling as a water-level window you can read across the room. The 108-ounce stainless basin resists the biofilm that plagues plastic, disassembly takes minutes, and the box bundles six replacement filters plus three pre-filter sponges, a generous starter supply worth real money. Around fifty dollars buys a lot of fountain here, especially for households tired of refilling tiny two-litre tanks.
What We Like
- Faucet-style arc converts stubborn tap-loving cats
- Very quiet operation with LED water-level visibility
- Big 108 oz stainless basin plus six included filters
What Could Be Better
- Dark basin interior makes grime harder to spot at cleaning time
- Wired-only design limits placement options
Best For: Tap-obsessed cats and value hunters wanting large capacity without premium pricing.
Flaws but not dealbreakers: The same dark interior that hides water stains also hides slime, so adopt a fixed weekly scrub schedule rather than trusting your eyes. Design clones under other brand names make warranty support a bit of a lottery, and there is no battery option if you want outage-proof circulation.
Skip it if: your cat drinks happily from any bowl — a faucet-style spout is a solution to a specific problem, and the plumbing-free Veken below is cheaper.
⭐ 5. Wonder Creature Cat Water Fountain with Stainless Steel Lid (Best Budget Cat Water Fountain)
Wonder Creature’s fountain reads like a love letter to the classic Catit design, refined where it counts: it is slightly quieter, cheaper, and smaller than the original it echoes, which is exactly the trifecta budget shoppers want. The stainless steel upper dish is dishwasher-safe and kind to sensitive whiskers, while the lower plastic tank keeps weight and cost down. A helpful LED warns you before the reservoir runs dry, sparing your pump, and the main pieces screw apart intuitively for cleaning. Three flow patterns — bubbling top, sliding stream, and calm pool — let you experiment until your picky drinker commits. At its typical street price it costs less than a month of fancy coffee yet delivers most of what premium models offer, and thousands of repeat buyers have kept it an Amazon staple for years.
What We Like
- Quiet, compact, and cheaper than the classic it imitates
- Dishwasher-safe stainless dish with whisker-friendly rim
- LED low-water warning protects the pump
What Could Be Better
- Not as library-silent as premium wireless rivals
- Plastic lower tank needs gentler, more frequent scrubbing
Best For: First-time fountain buyers and tight budgets who still want stainless hygiene up top.
Flaws but not dealbreakers: The pump hum registers in a silent room at night, though a white-noise machine masks it easily. The carbon filters need replacing every couple of weeks in hard-water areas, and the plastic tank will develop film faster than full-stainless rivals unless you stay disciplined.
Skip it if: your cat has chin acne or a plastic sensitivity, or if you want a dishwasher-safe bowl all the way down — here only the top dish is steel.
⭐ 6. Catit LED Flower Fountain with Triple Action Filter (Best for Picky Drinkers)
Few pet products earn cult status, but the Flower Fountain has, and the LED edition is its nicest form. Three flow settings let your cat choose between a blooming bubble top, a gentle stream, and a quiet pool, covering every drinking personality from playful to timid. The ergonomically rounded bowl sits low so whiskers never brush the sides, a detail anxious cats notice more than humans guess. Triple-action filtration catches hair, softens tap water, and reduces off-tastes, and the three-litre tank stretches refills for single or paired cats. This LED version adds a soft blue glow that doubles as a night light and makes the water line obvious at a glance. After years on the market it retains a huge review base documenting long-term reliability, and it remains the default recommendation for uncertain buyers.
What We Like
- Three flow modes suit every drinking style
- Whisker-friendly low bowl calms nervous drinkers
- Huge long-term review base proves reliability
What Could Be Better
- All-plastic body needs diligent weekly scrubs
- LED glow is ambience, not function, and cannot be justified as health tech
Best For: Picky, hesitant, or anxious cats who need encouragement to trust a new water source.
Flaws but not dealbreakers: The plastic surfaces grow the familiar slime ring faster than stainless rivals, so keep a bottle brush within reach. Filter cartridges are a recurring cost, the LED adds little beyond aesthetics, and the pump, like most budget pumps, eventually wears and is sold separately as a spare.
Skip it if: you want a wipe-clean stainless wetted path — the flower’s charm comes with a plastic body that demands more scrubbing than the steel picks.
💰 7. Veken 108oz Stainless Steel Cat Water Fountain (Best Stainless Value)
Veken’s fountain is the quiet overachiever of this list: an all-304-stainless, 108-ounce (3.2-litre) body for under thirty dollars, and the single best-seller in Amazon’s fountain category on the day we checked. That combination — full stainless at a plastic price — is why it earns the value slot. The suspended pump design is rated at a whisper-quiet 25 dB, the four-step snap-together assembly comes apart for cleaning without tools, and a wide water-level window makes refills obvious at a glance. It holds as much as the GIOTOHUN above for about $22 less, which for a single cat or a pair is simply better value. If you want stainless hygiene and three litres of capacity without paying for an app or a battery, this is where the money goes furthest.
What We Like
- Full 304 stainless steel body at a plastic-fountain price
- 108 oz / 3.2 L capacity matching far pricier picks
- Tool-free snap-together build with a wide water-level window
What Could Be Better
- Wired pump, so placement still needs an outlet
- No smart features or battery backup at this price
Best For: Value hunters who want stainless steel and a big tank without paying for connectivity.
Flaws but not dealbreakers: The “25 dB” figure is the seller’s own claim and we could not verify it independently — treat it as marketing, not a measurement. There is no app, no low-water alarm beyond the window, and like every wired model here the cord needs routing away from a curious cat.
Skip it if: you need cordless placement, outage-proof pumping, or a drinking-log app — those are the reasons to climb to the PETKIT or PETLIBRO picks.
Spec Claims, Checked Against the Sources
Two claims recur on almost every fountain listing, and both deserve a caveat.
- “Ultra-quiet, 25 dB.” A pump’s decibel figure depends on the water level, the surface it sits on and how far away you measure. The Veken and SohoTeco listings quote 25 dB and the PETLIBRO listing quotes roughly 30 dB, but none of those numbers come with a measurement method, and no independent lab figure we found is published for these specific models. Buy for the pump type — suspended or induction rather than a cheap fixed impeller — not for the sticker number.
- “Four-stage” or “quadruple” filtration. These badges describe a sponge, a carbon layer, an ion-exchange resin and a mesh, in some order. They remove hair and improve taste and odour, which is genuinely useful, but no manufacturer publishes a filtration-efficiency measurement, and the veterinary sources we used treat filtration as a hygiene and palatability aid rather than a health guarantee. The number that actually matters is how often you change the cartridge.
The one hard number worth keeping is the hydration target itself: about four ounces of water per five pounds of lean body weight per day. If your cat is not drinking that, the fix is fresh water offered in more than one place — a fountain plus a clean bowl — not a more expensive fountain.
The Bottom Line
If your cat treats the water bowl as decoration, a fountain is one of the cheapest health investments you can make. For most homes, start with the PETKIT Eversweet Solo 2: near-silent, cord-free, and the easiest teardown here. Cut the cords entirely with the PETLIBRO Dockstream Cordless, feed a dog-and-cats crew from the stainless SohoTeco two-gallon, convert a tap addict with the GIOTOHUN, cover picky drinkers with the Catit Flower or the budget Wonder Creature, and get the most stainless per dollar with the Veken. Every listing above was live and priced on Amazon as of 16 September 2026. Match the tank to your household, commit to a weekly scrub, swap filters on schedule, and enjoy watching your cat finally drink like they mean it.
Frequently Asked Questions
1. Do cats really need a water fountain?
Need is strong, but the evidence leans yes for many cats. Cornell’s Feline Health Center notes that some cats increase their water intake when offered a fountain, while individual preferences vary — and it lists chronic kidney disease, diabetes and hyperthyroidism among the conditions that raise a cat’s water needs. A fountain turns drinking into instinctive behaviour for many cats, and most owners report visibly increased intake within days of switching. That said, a cat who already drinks eagerly from wide, fresh bowls may not need one.
2. Which material is cleanest: stainless steel, ceramic, or plastic?
Stainless steel leads because it is non-porous, scratch-resistant, and usually dishwasher-safe, with ceramic a close second at higher cost and weight. Preventive Vet recommends steel labelled grade 304 or 18/8 and cautions against cheaper “pet use” steel. Plastic is affordable and lightweight but micro-scratches over time, harbouring biofilm and occasionally irritating sensitive chins. Whatever the material, weekly scrubbing matters more than the label on the box.
3. How often should I change the fountain filter?
Plan on swapping your filter every two to four weeks depending on water hardness, shedding volume, and the number of pets using it. A clogged carbon cartridge strangles flow and makes the pump strain audibly, which is your cue it is overdue. Buying multipacks cuts the per-filter cost dramatically compared with singles.
4. Are cat water fountains loud?
Modern fountains are quiet enough to sit beside your bed. Wireless and battery designs like the PETKIT Solo 2 and PETLIBRO Dockstream are nearly silent, while good wired pumps produce a low murmur that fades into background noise. Any fountain that suddenly grows loud is telling you its filter is clogged, its water level is low, or its impeller has scaled up — the three failure modes in our list above.
5. How does a cordless fountain work day to day?
An internal rechargeable battery spins the pump for weeks per charge, so there is no cord to place, hide, or worry about chewing. You top off water as usual, recharge on a monthly rhythm, and enjoy freedom to position the fountain wherever your cat prefers. Expect marginally weaker flow near the end of each charge cycle.
6. What size fountain does my cat need?
Cornell puts a cat’s need at roughly four ounces of water per five pounds of body weight per day, and Preventive Vet’s range is 3.5–4.5 ounces per five pounds — so a 1.5 to 2 litre tank covers a single cat for two to four days. Two or three cats deserve 2.5 to 3 litres, and any household sharing the fountain with a dog should jump to large-format models like the 270-ounce SohoTeco. Fresher water beats more water, so err toward easier refills over giant tanks you neglect.
7. How do I get a scared cat to use a new fountain?
Patience wins. Place the new fountain running on its lowest setting across the room for a few days so the sound becomes furniture, keep the old bowl filled nearby, then gradually close the distance. Reward any sniff or sip with praise or a treat, never push their face toward the water, and try different flow modes; a former tap addict may respond instantly to a faucet-style spout.
