Petlibro’s Stainless Steel Fountain holds 3L. Selene’s Doggy Fountain offers 4L or 7L. That is a clear hardware difference, without needing to guess how many days any of them will last for a particular dog.
The short answer
Our starting point: the Doggy Fountain
Two useful sizes, a choice of power and a simple cleaning routine. A well rounded starting point for a dog household.

01 / The detail
Start with capacity and footprint
A smaller reservoir may be sufficient for your setup and easier to position. A larger one holds more water but takes up more room and weighs more when filled.
We prefer Selene when the extra capacity and choice between plug in and wireless power are useful. A compact Petlibro setup remains worth considering when those are not your priorities.
02 / The detail
Read the filter schedule
The current Petlibro listing recommends replacing its filter every two weeks. An annual comparison that assumes monthly replacement for every fountain would not reflect those instructions.
Compare the compatible pack price and the maker’s interval together. We leave exact annual totals out when the inputs are not like for like.
More capacity is useful when your setup needs it.
03 / The detail
Our recommendation
Start with the Doggy Fountain if you want more choice in reservoir size and placement. Its three steel parts and stated dishwasher compatibility also make the cleaning arrangement easy to understand.
Before buying either product, confirm the selected configuration, included filters and current offer. We do not claim Selene is the cheaper choice in every comparison.
