Very playful and happy. Has never bit anyone eventhough my son always annoys him. House trained but will have an accident only after giving several warnings. In other words he will come to you then go to door several times before he will go on the floor. He also eats his poop if left in a cage. He got 2 shots so far, one from the breeder and one from the Veterinarian. I got him for my daughter but she thinks shes to cute to clean up poop so she doesn't want anything to do with him at all. These little dogs live like forever and I don't want to take care of him for the rest of my life so we decided to let him go.
