This is like having a toddler and a sixteen year old boy play together, Most 16 year old boys aren't interested. Riley wants to play, the humping is how dogs interact with other dogs. I've read of this happening before, there is just too much of an age difference. Neutering Riley will cut down on the humping, but maybe someone else can give you advice on how to help them tolerate each other better. By the way, Cesar suggests taking you dogs on walks together; this helps them to feel more bonded with each other. It also might tire Riley out a little. Good luck! |
