slightly aggressive red heeler/ greyhound mutt

My dog is about 14 months old. He has always been slightly fearful of other dogs. The dog park used to be a total nightmare for him. He would tuck his tail and cry and hide behind me. He has gotten better in that sense, he even plays with other dogs. For some reason though he always takes it too far now, especially with puppies. He will even play at first, but then he will snap. Something happens mid play and he gets mad and will start barking and growling and showing his teeth. He has never drawn blood from another dog, but I am afraid he will if I don't stop it. He changes from friendly to aggressive so quick its hard for me to see it coming and stop it before it happens. Once it has started, he remains focused. No time out or distraction will make him forget. He will go back to that dog immediately and start pinning it on the ground and growling and chasing it and will not stop. He will not submit ever! Don't know what to do. He hates dogs on leashes also. Seems like he would like to attack them.

Stay away from dog parks
by: Adam G. Katz


Stay away from dog parks. It's an unnatural environment, from a canine behavior perspective. They were created to make HUMANS feel better about their dog ownership experience, but it is not normal for a dog to be thrown into an environment with so many other dogs from varying packs. Plus-- the people who go to dog parks rarely have very good control of their own dogs, so ... you're just asking for a dog fight, even if your dog is not the instigator.

Still-- You'll need to address the aggression issue, when you're out in public with the dog. This starts by employing a "Nothing in Life Is Free" approach so that your dog starts to respect you, when you tell him, "No!" and is reinforced by using the proper training collar for your dog's temperament (and learning how to use it, of course).

Employ the "Nothing In Life Is Free" approach, so that your dog starts to view you as the "pack leader." If your dog doesn't see you as the leader, then your corrections will be meaningless. So, if you're doing subtle things (inadvertently) to undermine your leadership role around the house-- it will be counter-productive.
