20 month old urinating in sleep

[Dmruti22]

After having a UTI that was treated, my 20 month old pointer mix pees in her sleep. It's is only occurring after we have been at the dog park where she plays a lot and drinks a lot of water. When we get home she is exhausted and crashes....that is when the urinating happens. I have noticed on days we don't go to the park it doesn't happen. Is it normal to pee like this just because she drank a lot of water while playing?
