Hello, we just recently got a 4 week old baby girl pit bull from a breedier, when we first got her, poop was semi solid, and she always would let us know when she has to go potty. But her poop is very wet and green its been like that for a few days now, she still lets us know but she can't hold it for as long so lots of accidents are starting to happen. We are feeding her wet puppy food and milk that the breedier gave us. Would this be the cause? Or might there be another reason. My girlfriends starting to think she might be sick and she's very worried.
