If anyone has a quick easy training method?
Sorry, I'm honestly not making fun. They really are hard little buggers to train. My Gracie wasn't fully trained until a year and at 2 1/2 shes still not 100% trustworthy. That doesn't mean that will be the case for you but some of them do take a while. Sounds like you're doing the right stuff and at least he's peeing outside. Good luck and trust me, I feel your pain!
