Pretty much what the tag and title say.
I usually top up my dogs inside water bowl multiple times a day (400 ml cup of tap water each time). He usually prefers to drink inside. I washed out his bowl twice this week, both times filled it with fresh water straight from the kitchen tap and he wouldn’t touch it for multiple days both times. He was drinking outside instead, but not enough for my liking, so I switched to wet food for extra hydration. I was contemplating taking him to the vet, if he kept not drinking inside, ready to drop multiple hundreds of dollars on tests for his bladder and kidney function, since he’s getting older now.
Decided to clean his inside bowl a third time tonight, but I put it down empty and filled it up with the cup I usually use, instead of filling it straight from the tap.
He started drinking within minutes and guzzled down close to a litre of water in less than an hour. My dog apparently thinks that ‘inside cup water’ from the bathroom is different/superior to straight tap water from the kitchen, but will still drink straight tap water from his outside bowl that he sees me filling up in the laundry sink. My dog is an idiot
Edit: some people are confused about the size of my dogs water bowl. It takes over a litre of water. The cup I top it up with takes about 400ml, if I don’t fill it up all the way. I’m clumsy and half the time will spill some of the contents of his bowl, if it’s full and I carry it around between rooms. So I just top it up during the day with the cup (have used the cup pretty much exclusively for years now) until it’s time to do a complete swap over in the morning.
I also fill up the cup in the kitchen half the time, if I don’t want to go in the bathroom when it’s cold. He drinks water from all throughout the house without issues, if it gets delivered in his cup. He’s just a diva.
