Reggie is the perfect example of size mattering. He is a little guy and in his mind the best defense is a good offense. Right now he would rather not socialize with other dogs. Reggie is a cutie of a dog and he is great of people and that is enough for him.  In time when he settles into a good home with a good routine he is likely to be open to having canine friends.  He just needs to start with a home, lots of love and some training.
