My name is Jane. I have been working professionally with animals especially dogs in both health and behavioral issues for over 18 years. I have over 14,000 satisfied customers. It will be my pleasure to work with you today.
Thanks for all that information. It is helpful. Right now your new dog would be uneasy. She has probably been taken out of the only home she remembers. That probably makes her very uncomfortable as she has no other family to help protect her. Things that normally might not cause her to react would now. You are on the right track with obedience training.
Obedience training will help. It will help the dog understand what you expect of her and help her bond with you quicker. It usually takes a dog a couple of weeks to realize that they have a new home. Once she does, she should start seeing you as part of the pack and if she sees you as the boss, it will be your job to protect her from other dogs and people and her reaction shouldn't be as pronounced. Of course, you have to take over that role. You should not let dogs run up on her or let people pet her at this point until she is comfortable around them. Just tell people she is in training. You can have them talk to her and toss her a tiny piece of vienna sausage or liver so he sees them in a positive way. I'd suggest carrying a hooked umbrella on your walks. It can be opened and used as a barrier between dogs and the hooked end can be used to pull a dog off of another one if it should come to that.
There are ways to help dogs that are reactive to other dogs. One method that is relatively new is called BAT. You can read about this method below.
It will be helpful if you can find someone with a dog to help you once you have your dog listening to commands consistently. What you will do is have your dog on the leash. You will have your helper off in the distance. Your helper will gradually move their dog a bit closer to you preferably walking past your position in the distance. As long as your dog ignores them, you can give your dog praise and a treat. The second you see her fixate on the other dog or show any other sign of aggression (hair standing up, etc.) give your dog a correction by giving a short tug and a firm low toned "NO". It shouldn't take your dog long to realize you will not tolerate the aggression and that if she ignores the other dog, she gets treats. Once this happens you can repeat the training moving the other dog closer until she is no longer trying to lunge at other dogs. You will need to practice this when you and your dog are walking as well.
This technique can be used for tall men as well though once she is more comfortable around them, you should have them also toss her some tasty treats. The training can also help with visitors coming into the house. You can have her sit and wait for visitors to be seated before giving her a release command. Have visitors give treats as well. When first teaching her to sit, you can keep her leash on and slip it under your foot to keep her in place until she learns. Once she is obeying and staying, reward her with the tasty treats. The treats provide positive reinforcement and is a great positive training method.
You can also teach her not to bark. Your method may help, but it is using a physical reprimand (holding the mouth shut). Physical reprimands can lead to the dog feeling you approve of physical reprimands. This might cause a dog to use a physical reprimand if they feel one is needed and their only physical reprimand is a bite. I recommend teaching the speak and quiet command. Dogs seem to learn quiet quicker if they first learn the speak command. The following site explains teaching speak and quiet commands.
If this doesn't work, you may have to try a citronella bark collar or an ultrasonic bark collar. These techniques should help with the issues you are having.
