Hi, I ´m sure I´m on the right place, well I´m a trainner and I have to train a female pitbull terrier, the owner told me and show me the problem
Those bitch inside the home, owner´s home, has a good behaviour, she accept other dogs, she lives with other 6 dogs, and other people, could be extrange, but she changes complete her behaviour when the owner take her with the leash and go outer, when someone is approaching she try to bit, start to bark, but barking like as she is going to kill you. The other day whe four boys were approached those bitch put on down and wait them, like a hunter, and when those guys accross the street, the pit, jump, and try to bit, and bark, on this moment I told to the owner give a correction with a choke collar, but when he did it the bitch turn a round and try to bit him, I guess, when we increase the correction the bitch turns more aggresive. For 4 classes I have been working on the street, ussing to leashes, one tie to the three, and the other catch the owner, and when somebody is approaching I start to give her a piece of cheese, to pay attention to me. She doesn´t leave me approach them, when they are outer. I´m right on the system? please let me know if somebody knows other way to do that or to change this kind of behaviour I will relly appreciate it.

Marco, how old is this bitch, and how much obedience training has she had? I don't think I would start this way that you have described. I think, instead, she needs to be worked in obedience on a regular basis without any strangers or other dogs around, probably for at least 4 months, then introduce those things gradually and at long distances. The bitch should be redirected through obedience and heavy reward for ignoring the distraction. Slowly decrease distances as the bitch shows a willingness to follow commands rather than aggress.
In the meantime, the owners need to have complete physical control over her, and muzzle her when away from home to prevent any unfortunate accidents. They should keep her at a comfortable distance from other people and dogs when walking her, even if they have to cross the street or go the other way. By "comfortable distance" I mean that she should be kept far enough away from other people and dogs that her aggression is not triggered.
There is no quick and easy way to change this behavior. It will take a great deal of effort and time. Hopefully the owners are committed to doing so.

This dog has some serious problems. It must be addressed with a trainer who has experience with correcting this behavior. Giving the dog cheese will not solve this. This dog should not be around people until this behavior is corrected.

I aggree with Vince. This dog is not for everyone, and tricks will not fix her either. There are not many people that can handle a dog like this and train it to be a good citzen.
I would like to know how old this dog is? I find it hard to believe, if I am understanding right that this dog is no problem in the home, but turns into Cujo outside. THere must be other issues. There is for sure a big nerve issue with this dog. The envoirment that this dog lives in, coupled with the dog gentics and the owner, are not a good combination.

True, Vince. In person help from a more experienced trainer NEVER hurts.

Key observation

Probably true. She lives with 6 other dogs; who knows what kind of a situation this is. In a situation with a single set of dog owners, I'd say they have too many dogs. In a household made up of multiple dogs and dog owners, I'd say it's probably fairly chaotic, with a great deal of inconsistency, and too many dogs AND people. At least they are seeking help, though. I'd still like to know how old the bitch is.

So would I (the age). Given the information that has been given though, it is fairly safe to say that with that amount of dogs, and I am to understand that they are not confined really from each other, any training program, that is not extended to include adjustments in the home is going to fail. This situation is an accident waiting to happen, and it is a great to at least see the owner seeking out help as mentioned. I do feel that specific advise cannot be given over the Net, but only general ideas as this situation should only be addressed in person. This is not an easy problem to fix, and requires skill and experience, as this is a problem that could result in injury. Being that there is a lack of control and the dog is a handler fighter, oone thing would be safe, is MUZZLE this dog in public.

Thank´s a lot for everybody, the bitch has 8 month old, and she lives with 6 dogs more and she is not a alfa dog in those group.Inside the home the owner it´s a great leader a superalfa, and the owner today told me the mother is good family dog, but the father was or is a fighterdog, those poor dog has a stupid owner and he made a fightring with his dog, and now everybody have a problem with his daugther.Other thing is when she was a puppy, in carnival some kids,terrify her with a masks.
Well today we have been progress, because I ride the bitch on a football yard, and she didn´t kill me, and other people came us and I won her attention with a cheese, but I saw she could be start to change her behaviour when she is with the owner, and I start the obedience work with her and when I finished I gave the bitch to the owner to gone very fast at their house. It´s a good idea to work inside the home without nothing, but I guess when we have finish the obedience work, and we start to work outside maybe she turn a round her behaviour and forget the obedience commands. When we gave the correction, pulling the leash and a choke collar, she tried to kill us, but when we control over her, using food and try to pay attention to us we won.Today I worked in the afternoon 5:30 pm, and when the night are comming over us, she started to pay more attention to the people, the owner stayed 10 mt. away, but when she is with her owner, could be protecting him, and change again.
Marco

Sounds like the owner taught this behavior, whether intentionally or not. It's very easy to send signals that aggression is what you want, if you don't know what you are doing. That's one reason that aggression problems should be handled by trainers experienced in that area.
