I have three dogs. First we had our Jack Russle Patch, He started to poop in the house and then once we got our other two, black lab/golden retreiver mixes, they started to poop in the house too. I have tried to limit them to one room when we leave, but they are still all pooping in their space. Even near their food and beds. I am not sure what is causing this or how to make it stop. Please help me find a training method that works.
