It's a slow process, be patient and consistent with her. We adopted Bolt 6 years ago, he's 12 y/o and 3/4 Africain. We don't know his history, but at some point he got into a dog fight. He has the scars to prove it. When we walk, there are certain dogs that will trigger a violent reaction from him. Over the years I've gotten very good at reading other people, and how they walk their dogs, plus reading their dog's body language. A high straight up tail tightly wagging will send him off the rails. I've worked extensively with him to the point that he is manageable when he sees other dogs. I usually make him sit, or give as wide a distance as I can allow. BUT, he is a biter, so I'm extremely cautious when I'm around other people. All bets are off if that other dog is not leashed!! It does get better, and yes you can teach an older dog new behaviors, I certainly did.
The Canine Behavior Series…excellent articles/website!
This is a wonderful site to go to for all behavior questions that you may have. A definite bookmark site! Here is the intro for the articles
Unwanted barking, jumping up on people, pulling on the leash, mouthing and nipping, not coming when called… how many dog owners haven't had to deal with at least a few of these common canine behavior problems? It's never too late to train a dog, or to work on his or her behavior problems. Bad habits can be broken, good habits can be taught, and most importantly, with a little effort and love, you can make sure your dog stays a happy member of your family forever!
Should the training articles available here or elsewhere not be effective, contact your veterinarian. Veterinarians not specializing in behavior can eliminate medical causes of behavior problems. If no medical cause is found, your veterinarian can refer you to a colleague who specializes in behavior or a local behaviorist.
Great articles, a lot of good info.
