The Dog's Life

My cousin ended up getting himself locked up and he told his mom to ask me if I'd take care of the dog till he gets out. Now I'm fully responsible for this dog that I didn't want to be here in the first place. He barely lets me touch him and it's like pulling teeth to get him to go outside. Yesterday I came home to shit and urine all over my bathroom floor. But she said no, she wasn't taking that dog.
