I've worked at a couple daycares over the years, and I know first hand that not all dogs enjoy it. Of course it depends on the dog and the daycare setup, but it's possible your dog is holding his pee from nerves. It's also possible that he's playing constantly, and gets really thirsty and then drinks a lot of water. (Is the pee really yellow and concentrated? or clear, almost water?) My dog went to daycare when he was younger, and he would occasionally drink a lot there, come home and pass out and wet the bed (very dilute, almost clear). I was there with him though, and I know he was having fun, not stressed. Maybe you could ask the staff if they could take a few short videos of him throughout the day so you can observe his body language. Pictures can be deceiving sometimes...an "I was just playing super hard" smile can look a lot like an "I'm panting because I'm stressed" smile. A video would show you more. They should also be able to tell you about his daycare bathroom and drinking habits as well. If they can't keep track of that, then they likely have too many dogs. Also, the fact that he won't eat there indicates he's stressed to some degree. That could be because he doesn't like it, or he's overly excited to play with the other dogs...
Different daycares are set up vastly different, so there are tons of variables. My dogs have done well in certain setups, and been really stressed in others. If you have any doubt that he's having a good time, I'd probably stop taking him. especially if the staff won't take the time and effort to assure you he is enjoying it.
