Milo's bed wetting seems to be getting worse. I've asked the vet and he says it's just a puppy thing. Does anyone else have this issue? It seems like he might be holding his pee all night so he'll get a treat in the morning when he pees on his pad. But when he wakes up his little tummy is completely covered in pee to the point where I have to give him a tummy bath everyday. I'm worried this constant bathing will start to bother his skin.
