I have a pit bull puppy that is about 8/9 weeks old and the oldest dog loves her and will play around with her but the younger one, whom we thought would love her, is absolutely terrified of her. We set the puppy down and she runs to the young one and the young one runs away and jumps on the couch so the pit cant get her. We have tried to keep them apart for some time now but the doodle seems sort of depressed and stays in her crate constantly. Also since she has a "beard" she has recently been slobbering and her beard is constantly soaked in foamy slobber. Can anyone help?
