I have a 7 yr old pug mix, male and fixed. Last night he peed in his sleep. This is the first time he's done it and nothing else seems to be wrong with him. Aside from last night he's acting normal and peeing outside normally. What could be wrong?

There's really no way to tell you why this happened.

If he's acting normally today, he may just have had an accident, it can happen to the best of us. You're in a deep sleep, and don't wake up when you feel the urge to pee.

But that's just a guess, which is all we can do online.

It's best to take him to your vet, get him checked. It could be a UTI. If so, the earlier you catch it the easier it is to treat, and the cheaper too.
