Yoshi is very playful, hyper , aggressive . He is only like to sleep in my son room . He don't like another dog, cat or people outside , he will bark on you. He barkes a lot of the don't know you . Only he's family like us but not another people. He will bites you if he don't know you . And he will run on you . He's very territorial dog, that's why we don't bother him in the room if he was sleeping. He will cry if you leave him in the room if he knows he's dad ( which is my son) outside the room / like in the living room. .. he really hates outside the house . .. we're looking a new home for our dog, because my son is going to San Diego to go college and I can't take care of him . It's hard but I have to surrender our dog... I hope he will find a new home that he will take care of him just like us.. he really like to sleep in my son bed with my son.
