My name is Tippi!

I’m not sure if he has a mental disability or neurological problem.I have tried to get him diagnosed, but became a parent that was out of my financial reach.He is protective when new guests arrive , but adjusts after 5/10 mins once he gets to smell them. Mostly barking. He is a very sweet goofy dog, We like to describe him as Jim Carrey because of the way that he overreacts with his body language. He’s very enthusiastic and playful.

He is mostly used to adult
