I've own two dogs, a 6 year old BC x Collie and a 3yo BC. They are both females and get on famously together, although the BC has a strange habit, she likes to stick her bum in the other dogs face to the point of full on reversing and almost straddles the dogs head! She's been seen to do this to other dogs as well, especially when they are lying down. Is it an initiation to play or is she asserting her dominance?
She is a lovely dog though, very full of life and willing to please and she gets on well with most other dogs but has a distinct dislike for small yappy dogs. I'm not particularly worried about her behaviour but would just like some sort of reason behind it. Thanks
