I work at a vets office, which makes the situation even worse in my opinion, cause if you come into a vets office you should be ready to see all types of dogs in the waiting room NOT closed it, Ace was Closed in lol, Ace doesn't need any treats but he would sure love a good hug and pets! Yeah i don't think i've ever heard Ace growl, he grumbles when he needs to go to the bathroom but that's about it, the most dangerous thing about Ace is that tail...ow...
