I've got my 6 mo. old female black lab at a trainers kennel going through force right now. She has been there for a week and when I went to see her today she acted like she didn't know who I was. After about 5 mins of calling, etc. she finally came up to me and greeted me then she was all over me. It is kind of disturbing to me that she reacted that way. The trainer says that is normal since he is around her 24/7, but I have never heard of this? Has anyone ever heard of this kind of thing?
