Hi!
I've had this issue with Odin since he entered puberty; he's sort of aggressive towards young puppies - but ONLY husky & malamute puppies. He gets along fine with small dogs when off leash in the dog park, but once a husky or mal puppy comes in I have to chase him around to make sure he doesn't hurt it.
The first 'greeting' he does towards the puppy would be to run straight to it, wrestle a bit then bite the neck. The puppy was terrified and crying and he still won't leave it alone. It's scary to look at and scary for the puppy owner too. He'll growl and try to pin the puppy down, and bare his teeth when I pull him away. He'll go back to chasing and biting the puppy's neck if I let him go.
It seems like he's turned into a playground bully and I'm really concerned about it. How do I correct this behavior? We don't always meet husky or mal puppy during our visit to the park so I have only few chances to correct him so I need to do it right.
