Hello all, My roommate and I recently found a puppy. After a week of checking newspapers, calling shelters and looking for posters with no results, we have decided to keep her. We believe she is about 10 weeks old, and a border collie/lab mix. Because she was a stray we have no idea what her socialization history is. Kenzii is very friendly with people, and will warm up to them almost immediately. However, with other dogs she is very tentative. She will crouch low, tail between her legs (she acts frightened, rather than submissive. She won't expose her belly to the dog), or try to hide behind one of the people present. We have tried introducing her to puppies her own age, and older more mellow dogs, but she reacts about the same no matter who she is meeting. Any advice on how to socialize her without scarring her for life? Thanks!
