In my opinion, if you are in doubt that the correction was not hard enough.. it probably wasn't!

That brings up another question. With a dog that is acting agressive towards another dog should it be countered with a correction? Is that going to manifest itself into more of the same? Should there be some distraction training starting on a lower level?

This dog is still young. How much obedience are you expecting of her? 11 month old dogs don't do everything perfect. Slapping her and getting frustrated with her is obviously not helping. You are putting the dog in a fight or flight situation, and the dog is choosing to fight. Sounds like the dog only gets corrected all the time, when does she get rewarded? Why are you not using a crate when you have all these problems? When the dog gets mouthy put her up. You mention she steals stuff and runs around laughing at you. Sounds like she has free access to the whole house. How much exercise does the dog get? A high drive GSD needs a lot of exercise. I find it helps if they get a proper amount of play outside, throwing the ball etc. I like to tire my dogs out, then they relax when they are inside. You mention the dog is fine with children, other dogs, and people. It sounds to me like this dog is probably inside much of the day, getting bored so she steals things and eats the couch etc. looking for ways to get your attention. Get a crate and start using it, and buy some of Ed's tapes on raising a puppy. It sounds like all your issues are handling issues, not rank drive issues.

Estee wrote:"Don't feel badly for her, she didn't blink an eye. I came to the realization, that this dog is superdog and feels no pain. Fears nothing, not a loud noise, not a person, not even a much larger dog that has been aggressive with her."

I seriously doubt that what you wrote here is correct. Simply because 'you' can't see a reaction from this dog does not mean it is not having a profound impact on her.

I don't want to hurt Ed's video sales but in my opinion, you need to find a trainer who understands training GSDs and can show you how to handle this dog.
When I conduct obedience classes, most in attendance have no idea how to give an effective correction or how to praise their dogs for the right behaviors. They all think they know, until they see me do it. Perhaps you do not need to be in top physical condition as Peter suggests, but he is right on about being capable of giving an effective correction and the timing good dog training requires.
Perhaps you are asking for way too much as far as behaviors from such a young dog. Seems many people think their puppies should act like adults almost immediately. It sounds like you are simply fighting with your dog and never making what you want clear to her.
It's clear to me, from what you wrote, that this dog does not understand and your constant conflicts with her are making it worse. You also seem convinced this is a "rank" dog. I am doubting that and would say this is more than likely simply a CONFUSED dog. I am not surprised that she has chosen to growl at you considering what you are doing to her. If you keep it up, it won't be long until she really bites you. IMO, she would be justified.

Find a trainer capable of helping you. Where are you? Maybe someone here can recommend a trainer.
Also, if you cant even correct and make clear what you want using a pinch collar, you have no business escalating to an e-collar. JMO.

Sounds like Bernard's kind of dog. If you are in the southeastern US, you can catch him at the seminar Will Rambeau is sponsoring next week. If anyone can help you with this dog, he can.

Bernard will also be at Leerburg's in western Wisconsin the first week in July.

i have never had a dog like this, but have heard about them. i would compare them to a spring. the more you compress a spring the greater the force it returns. the more you fight her, the harder she fights back. i believe it will take a completely different approach to train a dog like this. ordinary training and correction methods will only serve to make her a dangerous dog. just out of curiosity......what kind of breeding is she out of?

this is a nice high drive pup it sounds like who really does not know the "rules" and whose instincts are strong.

I have also been accused of not being able to give a good enough correction strength wise by a former trainer. In my case, the training was wrong for the dog. Changing the training is more effective. Also, sounds like the dog needs more work or exercise if she can be quiet and loving in the family...perhaps you bit off more than you bargined for in this particular pup and she would be better off with someone who wants this type of drive.

I have a puppy here who also is very high drive, very mouthy and uses his feet in play. I would never correct him by hitting or slapping or lightly punching him! I always have a toy for him when I have him out and try to get him plenty of outside pen/play time. This puppy loves to bite - last week struggled not to go in his crate, broke loose from me, grabbed a puppy sleeve which I had a heck of a time getting off of him in the first place, and had tossed behind the crate, out of sight. He took off back to the field...running loose for 8 or 10 minutes carrying that sleeve in a full grip before we just sat down and ignored him because we could not catch him! When we quit playing his game, he came to us. You have to take every situation individually, and work with it. Sounds like you are frustrated with this girl and she is not the right match for you.

lee, i'm glad you hopped in here. while i was outside doing chores i was thinking about this little dog. i see the difference in training her as the difference between training a pleasure horse and a race horse. the pleasure horse being trained to stay behind the bit and the race horse being trained to go into the bit. i know you know what i mean. this is what i was trying to say when i drew the comparison to the dog and the spring. maybe you can say it better than i did. but i agree, it is probably an example of a mismatch. charlie said it right when he said it sounded like bernhard's kind of dog. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

I would like to clarify what I may not have made clear in my last post. An "effective correction" does not, IMO, have to equal a hard correction. It is a correction that works for that dog and makes clear what you are trying to communicate. Also, correction alone is not the answer.
Great analogy Patricia.

This dog sounds to me like she would benefit from calm handling.. quick rewards.. and some rules to play by. Along with a ton of exercise! Where are you located.. so someone can point you in the direction of a decent trainer..
