i'm sure it's usually true. but it isn't always true.

i believe the reason my puppy did not turn into a dog-aggressive dog is because by the time he came to me at 12 weeks, he had been part of a pack his whole life and had developed unusually good canine social skills. he continues to expect the best from other dogs.

I would tend to agree with Ed up to about 98%. I have seen dogs be okay around other dogs after being attacked or jumped by another dog. I use the word okay, because I have seen the same dog turn and become fearful and/or aggressive when another dog is too pushy.

You just never know when the behavior will surface.
My Bloodhound is great for dog aggressive or fearful dogs. He pays absolutely no attention to any dogs (other than members of his pack, and even then he could really care less) so we use him to walk side by side with other dogs.
We walk quickly and stay calm and usually the other dog will relax once they figure out that Max is not going to do anything.
This is when the other dog starts to want to check him out and smell him. When that happens, Max just keeps plodding along smelling all the good stuff. He has never turned and tried to smell, growl at or go after another dog.

PLEASE know that we keep leads loose but are far enough apart to where if Max starts to turn towards the dog, each of us can go wide without accidentally correcting either dog.

I am not saying that any dogs are cured, but it seems to help them relax a bit more at training and when on walks with other dogs.

I NEVER walk a dog that is "nosy" with a fearful dog. My Mal is actually turning into a good dog to walk with. She is too snooty to pay attention to a short time member of the pack.

Richard, I actually do not own the "Your Puppy..." DVD, so I'll get back to you on that challenge. If it seems petty, well its only because I am also an intact male, Ha-Ha! My puppy is now 9-months old. When he was 3-4 months old he was attacted by a stray while we were on a walk. Soon after that I made the mistake of trying to introduce him to a friendly old female as to show him not all dogs are mean. Well, they went nose to nose, He licked her on the muzzle, lowered His head a little and she bit Him on the side of his face. He was dog aggressive after that. But, I have spent months taking him places where there are other dogs and making him ignore them. I am happy to say he pays little attention if any to them. Now on the other hand, When he see's that bitch, he goes nuts trying to get back at her.It seems fair to me so I only restrain him, but I do not correct him. I am a Christian and was taught to turn the other cheek, He's not been babtised yet, so I let it go. If I had found Ed sooner this would not have happened. His advise on not associating your dog outside his pack is good advise. I do not let other humans pet my dog-also good advise.I beleave that if your dog trusts you as the leader, then he knows you will protect him.

Dealing with Dominant & Aggressive Dogs DVD: Printed on the screen: There Are Exceptions To Every Single Rule In Dog Training.-Richard, I would not trust anyone who did not believe in exceptions. I trust Ed.
