Hi! This is Teddy's sister Sam. Teddy is SO adorable! The way he thinks he's bigger and stronger than everyone else! He always considers himself the dominant one in the family. Do any of you know Why his is so agressive? Or how we can help it? He is always barking at my friends when they come over...but once 10 minutes passes, he loves them to death! Then the next day, he wants to be mean and try to bite again. The only people he has always been permanatly nice to is family and two of my closest friends that he has known since he was a baby puppy. Anyone know how to help get him more socialized???
