My last dog was not. I would lay on the couch to pet him.... and he would nip at me if I did it too much because he would get annoyed.
My new pup is the exact opposite. She loves to cuddle and be petted. Most of all she love love loves belly rubs. Just walk near her and look at her and she'll turn onto her back for a belly rub (see picture) If I stop petting her she'll paw at me because she wants more
