Hi I just recently adopted two papvillons they are both 6 year old, it's a brother and sister. The brother has adjusted very well but the sister is very timid, when I call for her she hesitates to come to me and will walk backwards to me. She won't eat her dry food so I've put a little milk in it to soften it up and she'll just drink the milk. What can I do? She won't walk upstairs or downstairs, she won't jump onto the couch when I signal for her to do so. I know that might be a good thing that she doesn't jump on the couch but I just want her to be comfortable and to me is seems like she has some anxiety and I don't know what I should do. Please Help!
