I saw an episode on "It's me or the Dog" this season. It wasn't a yorkie but the behaviors were exactly the same. I think it was a husky.
Apparently, your dog (according to this show) views himself as above your boyfriend in the pack and either above you or at least on equal level.
A dog should always be on the low end of the totem pole in the pack. And yours is NOT. He is demonstrating behaviors that show dominance. He probably never had to show those behaviors before, because you always allowed him to be equal or dominant and now his position of dominance is being usurped by your boyfriend.
The peeing on the couch and in your bed is the dog's way of announcing his presence in the pack. He is putting his scent in the areas that he feels he has dominance over, or wants to control.
You are in for a lot of work to be done to get back on top of the pack and to get your yorkie back to the bottom. You need to look up dominance issues on the internet and you will find many great ways to re-establish yourself (if you ever were) as the leader in your pack. It is going to take work to correct the behaviors, but you and your dog will be much happier when you do! |
