Is this bullying? How to handle
Dexter is 8 months today and becoming a brat teasing my female dog and other dogs. I have started to take Dex to the dog park only once a week, when I have my daughter with me because for the past couple of weeks he has been attracted to the dogs that don't want to play with him. He keeps licking them in the face though they clearly don't like it. He's also been doing this to my 14 yr old shih tzu who is in heat. She will bite him in his mouth and he still tries to lick her face.
Yesterday I took him to the dog park along with my neutered maltipoo. A lady brought in her neutered dog about 45 pounds and about 6 or 7 dogs immediately went after the submissive dog. My maltipoo tried to hump the dog, I immediately grabbed him and removed him. But then Dex also joined the other dogs pinning the 5 month old to the ground. I removed him too and took him to the other side of the dog park to play with the other dogs. Dex has never done this before.
About 10 mins later the lady and her dog was in our playing area. ( I'm not blaming her because its my dogs being aggressive) but my maltipoo started growling and chased the pup and Dex did the same thing he pinned the puppy again. So I leashed them both and brought them home.
why are they bullying this dog. Will neutering Dex stop him from doing this? Considering my neutered male is doing the same thing. Anyone with experience know why the dogs at the park are doing this to this pup and what can I do about my two, to make sure they don't do this again.
