Fear Aggression In Puppies Towards Other Dogs
I just bought two Aussie pack mate brothers who are now 15 weeks old. They are very mellow and gentle with humans/children. My concern is they are very aggressive towards other dogs. They lunge at dogs showing their teeth growling and barking. If I introduce one dog (who is bigger and I believe is protecting his brother) then things go better but not much. My 7 year old Aussie mix still gets barked at but not snarled/attacked at anymore.
When I introduce them to a dog, I do it one-on-one. I hold my pup and pet the other dog saying,"nice" in calm voice. This works after about 5 minutes but I can hear my pup whine every once in a while as if he's scared. Eventually I give him room and he will get up to explore the other dog in a very timid way. It's as if they don't know how to play with another dog other than themselves and are afraid of all other dogs.
The vet told me they are establishing pack order. This is different. I think they would bite if I let them go.
They went crazy in Petsmart. It was like a heart attack in a shopping cart.
Any advice would be appreciated.
