I've had my dog for about four months now, she is a pitbull mix, only a year old, not overweight and is healthy from what I've been told(havent been to the vet for this and I'm not sure if I should or not?). For about 2 months she has been sleeping in my bed, and only for the past few days has she has been sweating a lot in her sleep. When she would move I could see and feel a large area on the bed that was wet, her side and back was wet too. At first I thought she had peed, but it didnt smell like pee, it smelt like wet dog. And it's only in her sleep, she will take a short nap by my side and will wake up to a wet spot on the couch, her and me(if she was leaning or lying right beside me in her sleep). I'm really not sure of what's happening and if there is something wrong with her, I'm honestly quite concerned and not sure of what to do. Please help.
