I am trying my best to potty train my 5 mth old but I am still having the same issues. He does great about going to the door when he needs to go to the bathroom but the problem I am having is when he is in his kennel I cant get him out fast enough before he begins to pee. I say no to him while he is doing it but he does not stop. I am so frustrated with this!! How can I get him not to pee in his kennel?
