Hi all:
My dog is a 4 year old cockapoo. She is a generally very quiet mild mannered dog. She does go bananas when the door bell rings, but once the person is in the house, she settles down to her usual calm, quiet self. My major question is regarding her unsocial behavior. She is fine with humans, it is other dogs that she will have nothing to do with. It goes so far that she won't even go near a little miniature poodle puppy. As soon as the little puppy goes towards her she immediately moves away. The puppy is very little compared to her. She does the same with a neighbor Weimaraner puppy. This puppy is bigger than her but still a puppy. What to do, what to do.

You seem to have a very timid puppy. Introduce things to her one at time. You can enroll her in classes to help her socialize.
