My 9-month old Shep Maddux is somewhat dog-aggressive. You ask what I mean by "somewhat"...let me explain. There are some dogs he will try to go after, and others he has absolutely *no* problems with. There is no rhyme or reason to what kind of dogs he doesn't like, but so far he's tried going after a Belgian Teruvren in our SchH group, a St. Bernard mix, and a Pointer-mix somethingorother that lives in our apartment building...among others. I give him a hard correction with the prong collar, but he doesn't seem to get it. I haven't tried an ecollar yet, but he's collar-wise already. (He's been shocked before.) He's Shiloh/East German and Czech in his breeding, and I'm doing SchH with him. (Mom's the Shiloh half). Any ideas? He hasn't gotten hold of any dogs yet, but I want to nip this in the bud before it gets any worse...

You need to nip this in the bud quickly, I'm surprise he can do SchH training and be so dog aggressive this can get you disquailifed. Imagine him doing Ob on the field and he takes off after another dog on the side line. Big "DQ".

And cussing and fussing, A lot of these guys have $$1000s in their dog.

I'd stage a practice of other dogs walking by with their on owner on leash and out of range. As you stand with your dog on leash in a sit, you want to watch for signs of aggression before he up barking and pulling on the leash. Watch for staring at the other dog, hair on its back raising, ears and body becoming erect, lip raising. When you can stop him before he is enraged you have a better chance of controlling this.

I'd call his name (draw his attention away from the dog on to you) tell him sit, bring out treats (chopped wienrs or his toy) give him a treat if he sits and is quite, pat him for sitting.

If you use the toy get his attention and toss the toy behind you (away from the other dog) a short distance let him retreive it and pat him for retreiving the toy and sit him. The things is to distract the dog from the unacceptable behavior and praise it for acceptable.

If you have a problem with this, Lets say the dog is so intense on trying to get to other dog, that he ignores you. Then you have to use complusion.

I'd let your 6'6 better half or a Pro trainer do this and then have him teach you the timing. Or get some help form the SchH club you train with. Timing is very important here you don't want to give the wrong signal that you are fearful of the approaching dog (by tighten the leash) or that you are praising (by prasing him while he still barking and standing before he in full sit) his poor actions.

Get some help withthis quickly. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

I'm with Don on this, you have to stop it like yesterday. It wouldn't matter that he behaves around some dogs and is 'prejudiced' about others. He needs to learn it's not up to him anyways. If you are ok with the other dogs, that's what matters. While he doesn't have to romp joyously in the woods with every dog he meets, he needs to have manners and be 'polite' around all of them.

I've heard that e-collars can add to the aggression on an issue like this, so I would NOT go that route. I'd also use your class instructor to set up situations so you can learn to teach your dog what he has to learn, rather than the confusion that's currently existing with him.
