Best PetSafe Drinkwell Big Dog Pet Fountain: 3 Picks

As an Amazon Associate we earn from qualifying purchases. Details

Shoppers looking for a big dog pet fountain can compare one PetSafe Drinkwell machine and two complete large-dog alternatives: the 450 oz Outdoor Dog Fountain, the SHARLOVY 8 L stainless-steel fountain, and the SOVELIVEE stainless-steel fountain. The main choice is indoor placement versus indoor-or-outdoor placement, followed by capacity, footprint, bowl design, and included filtration parts. This comparison excludes replacement filters and pumps because those accessories cannot dispense water alone. The two non-PetSafe options are clearly identified rather than presented as Drinkwell models. Use each product page to confirm the cord route and current package before ordering.

Quick answer for three complete fountains

Choose the SHARLOVY when you want an 8 L stainless-steel indoor fountain with a 2.8 inch splash guard and a pump the listing describes as under 20 dB. Choose the Outdoor Dog Fountain when its 450 oz capacity, large-dog designation, deep bowl, and indoor-or-outdoor wording fit the intended area. Consider the SOVELIVEE alternative when two flow modes, a viewing window, and three included filters matter more than staying with PetSafe. For bowls rather than powered fountains, see the no-spill dog water bowl guide, slow-drinking bowl comparison, and large-dog bowl guide.

The capacity choice is 8 L or 450 oz

The SHARLOVY listing states an 8 liter capacity, and its title gives 2.1 gallons. Converted, 8 L is about 270.5 US fluid ounces (8 x 33.814). The Outdoor Dog Fountain states 450 fluid ounces and includes two reservoirs. That is about 179.5 fluid ounces more than the SHARLOVY (450 minus 270.5), which makes the Outdoor model the clear capacity choice among the two products with a consistent capacity.

Capacity does not establish a fixed number of hours or days between refills. Neither product entry supplies a consumption schedule for a particular dog. The practical comparison is therefore limited to the two stated capacities. A household that wants a smaller stored supply in a stainless-steel body can choose the SHARLOVY, while a buyer prioritizing the largest stated supply can consider the Outdoor model.

The product pages and manuals should still be checked once the fountain is in use, especially for filling instructions. Follow the operating instructions for filling and minimum water level rather than creating an unsupported refill timetable.

Indoor placement favors the SHARLOVY

The SHARLOVY listing describes an indoor automatic water dispenser. The model is W10 Pro, the body is silver stainless steel, and the listed item weight is 2.09 kg, or about 4.61 pounds (2.09 x 2.20462). Product dimensions are not stated. The only measurements given are package dimensions of 14.61 by 11.61 by 7.95 inches, which describe the box and should not be read as the fountain’s footprint.

The listing describes a 7 cm (2.8 inch) high splash guard as a no-spill barrier, a tipping-resistant and scratch-proof body, and a window for checking the water level. The same bullet pairs the splash guard with non-slip parts, but the details are not stated. Those features are relevant for a dog that approaches the fountain enthusiastically, but they are not a promise that the unit cannot move or spill. The location should still allow refilling, filter changes and cleaning.

The SHARLOVY’s power source, voltage and cord length are not stated in the product information used here. Plan the installation around the manufacturer’s instructions and an appropriate indoor outlet. Do not extend the Outdoor model’s placement language to the SHARLOVY, which is a different brand.

Indoor or outdoor placement favors the 450 oz model

The Outdoor Dog Fountain explicitly states outdoor use, and PetSafe also describes it as suitable indoors. The product information lists UV-resistant plastic, a deep-sided bowl, and a design intended to reduce splashing and spills. Its listed dog-breed size is Large.

This model measures 20.5 inches long, 13.9 inches wide, and 15.5 inches high. At 10.2 pounds, it is heavier than the SHARLOVY’s listed 4.61 pounds by 5.59 pounds (10.2 minus 4.61) before either fountain is filled. The larger housing and two reservoirs require a more generous placement area.

Outdoor wording does not replace the operating manual. The fountain remains corded electric. Follow the maker’s placement, temperature, cord, cleaning, and electrical instructions. If the proposed location does not satisfy those directions, use a different location rather than improvising an installation.

Falling stream and bowl access

The SHARLOVY listing describes a patented water outlet with a swirling flow that is meant to draw pets to drink while pushing hair and debris toward the filters. Adjustable flow is not stated, so do not assume the stream can be changed.

The Outdoor model uses a free-falling stream. Its distinguishing feature is the deep bowl rather than several stream attachments. PetSafe describes the higher sides as a way to reduce splashing and spills. A dog can drink from the stream or from the water collected in the bowl, subject to the operating instructions.

Owners choosing a fountain for a dog should decide whether the SHARLOVY’s swirling flow and splash guard or the larger deep outdoor bowl matters more. Neither product entry states that every dog will prefer moving water. Observe the dog’s use without turning a product description into a behavioral guarantee.

Filtration and complete package contents

The SHARLOVY listing describes five-stage filtration that starts with a pre-filter sponge to trap hair and large debris and protect the main filter. The later stages are not described in the product information used here, and the included components are not stated. Confirm the current box contents and the replacement filter type before ordering because replacement supplies may be sold separately.

The Outdoor Dog Fountain package is more explicit: fountain, two reservoirs, carbon filter, foam filter, and pump. Its dual-filtration description assigns hair and debris capture to the foam screen and water refreshing to the carbon element. These are parts of the complete machine, not separate fountains.

A replacement pump cannot serve as a dog water fountain by itself. The same is true of a carbon-filter pack or foam-filter pack. When buying maintenance supplies, match the exact model or part information on the product page. Similar Drinkwell wording does not prove cross-model compatibility.

Cleaning access changes the daily routine

The SHARLOVY listing describes its stainless-steel body as dishwasher safe. That statement comes from the listing; it should not be extended automatically to the pump or electrical parts. Read the disassembly and washing directions before placing any component in a dishwasher.

The Outdoor listing includes a separate pump and filtration parts, as the package list shows. Its two reservoirs, deep bowl, foam filter, and carbon filter create more individual pieces to inspect. The larger capacity does not remove the need to check the bowl, water level, filters, and pump.

Choose the model whose parts and placement fit a cleaning routine you can maintain. Do not invent a cleaning interval when the product information does not supply one. Check the manual for the schedule and procedure tied to the exact model.

The three complete fountain picks

SHARLOVY for a quiet stainless-steel indoor option

The SHARLOVY is an 8 L stainless-steel pet fountain, model W10 Pro, with a listed item weight of 2.09 kg, or about 4.61 pounds. The listing describes a 2.8 inch splash guard, a swirling water outlet, five-stage filtration that starts with a pre-filter sponge, a level-check window, and a pump it says runs below 20 dB. Power source, voltage and product dimensions are not stated.

This model fits a large-dog household that wants a stainless-steel fountain and does not need the Outdoor model’s much larger reservoir. The dog-breed size field reads Giant, Large, Medium. The splash guard and the swirling flow are the features aimed at messy drinkers and at moving hair toward the filters.

Its main limitation is missing numbers: product dimensions, power details and included components are not stated, and the listing describes indoor use rather than outdoor. Skip the SHARLOVY if the fountain must be placed outdoors, if the 450 oz capacity controls the purchase, or if you need verified dimensions before checkout.

Outdoor Dog Fountain for maximum stated capacity

The Outdoor Dog Fountain states 450 fluid ounces, large-dog sizing, and indoor-or-outdoor use. Its UV-resistant plastic housing measures 20.5 by 13.9 by 15.5 inches and weighs 10.2 pounds. Included components are the fountain, two reservoirs, carbon filter, foam filter, and pump.

The deep-sided bowl is intended to reduce splashing and spills. Dual filtration combines the carbon element with a foam screen that catches hair and debris. This is the stronger choice when the owner needs the largest stated Drinkwell capacity and has room for the stated dimensions.

Its limitation is bulk. The listed weight is above the SHARLOVY’s 4.61 pounds, and the package has two reservoirs to handle during maintenance. Skip it if the location is indoor-only and an 8 L fountain is enough.

SOVELIVEE for a stainless-steel alternative

The SOVELIVEE listing describes a large-dog indoor fountain with a stainless-steel body, two stream choices, a viewing window, and an indicator that changes color when the water level is low. Its package includes the fountain, cleaning brush, power adapter, bubbling spout, faucet spout, user manual, pump hose, and three filters.

This fountain is useful when material and included accessories take priority over the PetSafe name. The product information lists a 4.8-pound item weight and identifies Large as the dog-breed size. Its filtration description mentions PP cotton, activated carbon, and resin, while the viewing window lets an owner check the level without opening the unit.

The product entry contains conflicting capacity fields, so they are not converted or reconciled here. Confirm the current capacity and complete dimensions on the product page before ordering. Skip this alternative when the purchase must be a PetSafe Drinkwell model rather than a different brand.

How much larger the Outdoor model is

Capacity is the clearest difference. The SHARLOVY’s 8 liters is 8 x 33.814, or about 270.5 fluid ounces. The Outdoor model’s 450 fluid ounces minus 270.5 equals 179.5 fluid ounces more, and 270.5 plus 179.5 returns 450. Weight follows the same check: 10.2 pounds minus 4.61 pounds equals 5.59 pounds, and 4.61 plus 5.59 returns 10.2.

Footprint cannot be compared the same way. The Outdoor model measures 20.5 by 13.9 by 15.5 inches, which is 20.5 x 13.9, or about 285 square inches of floor. The SHARLOVY entry gives only package dimensions, and the SOVELIVEE entry does not provide complete assembled dimensions, so check those measurements on their product pages before choosing the location.

Measure the placement before choosing

For the SHARLOVY, product dimensions are not stated, so confirm them on the product page before measuring the area. Allow room to read the level-check window, refill the fountain and change filters. Do not wedge the fountain into a space where routine filling requires pulling on the cord.

For the Outdoor fountain, start with the 20.5 by 13.9-inch footprint and 15.5-inch height. Leave working room for both reservoirs and the deep bowl. The listed dimensions describe the product, but the manual should determine final clearance and placement.

Every powered fountain here needs an appropriate cord route. A larger dog’s normal path, the refill approach, and the cleaning route should remain usable. These are placement checks based on the stated figures, not new compatibility claims.

Avoid accessory and model mix-ups

Several products associated with Drinkwell are filters or pumps. They may be necessary maintenance supplies, but they are not complete fountains. A product must include the bowl or fountain body and operating components before it counts as a complete fountain.

Model confusion can also introduce unsupported numbers. Keep 8 L, 2.09 kg, and the 14.61 by 11.61 by 7.95-inch package size tied to the SHARLOVY. Keep 450 fluid ounces, 20.5 by 13.9 by 15.5 inches, and 10.2 pounds tied to the Outdoor Dog Fountain.

Do not import dimensions or stream arrangements from another fountain model. If a needed figure is absent, check the exact product page instead of filling the gap with information from a related fountain.

Situations that point to one model

An indoor household that wants a stainless-steel body, a splash guard and a pump described as quiet may prefer the SHARLOVY. It suits a straightforward indoor drinking station. The owner should still confirm its dimensions and power details on the product page, and that the space leaves room for cleaning access.

A large dog using a sheltered exterior area points toward the Outdoor model because outdoor use appears in its product information. The 450 oz reservoir and deep bowl distinguish it from the SHARLOVY. The corded power source means the operating instructions remain essential.

A multi-pet home should compare capacity and bowl access without assuming a pet count. The listings do not establish how many animals each unit supports for a set period. The Outdoor model stores more water; the SHARLOVY is lighter and states 8 L. Choose from those verified differences.

FAQ

Which fountain here holds more water?

The Outdoor Dog Fountain holds 450 fluid ounces, compared with 8 liters (about 270.5 fluid ounces) for the SHARLOVY. It also weighs more, at 10.2 pounds against 4.61 pounds. Select it for capacity only when the intended area can accommodate its body, two reservoirs, corded power, and cleaning access. Check the SOVELIVEE product page before comparing capacity because its listed fields conflict.

Can the SHARLOVY be used as an outdoor fountain?

The SHARLOVY listing describes indoor use and does not state outdoor use, so it is not recommended for outdoor placement. The Outdoor Dog Fountain explicitly carries indoor-or-outdoor wording and uses UV-resistant plastic. Follow that model’s manual for location and electrical requirements; an outdoor description does not authorize every possible exposed placement.

What filters come with the Outdoor Dog Fountain?

Its included-components field lists a carbon filter and foam filter along with the fountain, two reservoirs, and pump. The foam screen catches hair and debris, while the carbon component refreshes the water. Confirm replacement compatibility by the exact Outdoor model information rather than selecting a pack merely because its title contains Drinkwell.

How large is the SHARLOVY fountain?

The SHARLOVY lists a capacity of 8 liters and an item weight of 2.09 kg, about 4.61 pounds. Product dimensions are not stated; the package measures 14.61 by 11.61 by 7.95 inches. Check the product page for the fountain’s own size, and leave access for refilling and filter changes instead of treating the package size as its footprint.

Does the Outdoor model suit a large dog?

Yes, the product information lists the dog-breed size as Large. It also states 450 fluid ounces, a deep-sided bowl, and a 20.5 by 13.9 by 15.5-inch body. Those facts establish its intended category, but they do not predict an individual dog’s drinking preference or a fixed refill interval.

Are replacement pumps valid alternatives to these fountains?

No. A pump is one component and lacks the complete bowl, reservoir, and filtration arrangement. The same distinction applies to carbon and foam filter packs. This comparison uses only complete fountains: the SHARLOVY, the Outdoor Dog Fountain and the SOVELIVEE. Match future replacement parts to the exact selected model before ordering them.

Which model is easier to fit indoors?

The SHARLOVY has the lower listed weight, 4.61 pounds against 10.2 pounds for the Outdoor fountain, which measures 20.5 by 13.9 by 15.5 inches. The SHARLOVY’s product dimensions are not stated, so check its page for size, and check the actual available floor area, refilling space, and cord route before deciding.

Bottom line for these three products

Choose the SHARLOVY for an 8 L stainless-steel indoor fountain with a splash guard and a pump described as quiet. Choose the Outdoor Dog Fountain when 450 oz capacity, a deep bowl, and stated indoor-or-outdoor placement justify its larger body. Pick SOVELIVEE when two flow modes and three included filters outweigh the need for a PetSafe model. Treat standalone filters and pumps as replacement parts rather than extra fountains.
