3 month old rottweiler

Question
hi valentina,
i have a 3 month old rottweiler.unfortunately she recently was infected by parvo virus(even though i vaccined her).she has recovered and it has been one week.she was a calm dog before getting diseased but now she is very aggressive.most of the time you touch her she growls and bites really hard.she shakes her whole body too much which i heard was a symptom of nervousness.because of her serious biting i have lost my control many times and i have tapped her on top of the nose to stop this biting.this made her hand shy too i guess.she ducks when she sees my hand go up and sometimes snaps.please help me out.what can i do to stop these aggressive behavior??

Answer
Dear Karthik,

I am so sorry you are having to deal with this situation even though you have done everything you could to prevent it. This sounds like a serious trauma issue. Tremors and shaking of the body are definite signs of dire stress and sometimes include flat ears and shyness. Are you sure she didnt have an overly stressful treatment or time at the vet? You didnt mention in the question whether your dog knows basic obedience and is well socialized as well as exercised/walked daily? Here are a few things I can suggest:

1. Never, ever hit your dog. It does not communicate leadership to the dog. In fact it further confuses and frustrates a dog. You dont want a stressed, frustrated, grown Rottweiler on your hands.
2. Walking your dog every morning and evening for at least 30-60 minutes each as well as a 20-30 minute walk in the afternoon are a must. Expelling energy will make for a happy and a more easy to handle dog on your hands.
3. If you arm yourself with reading materials like those of Caesar Milan and Victoria Stillwell you'll be enlightened and feel a part of your dogs world like never before. They also offer ways to battle bad behavior with positive reinforcement techniques which work wonders. I am a huge believer and supporter of the positive reinforcement training and over all way of life.
4. If you feel at all uncomfortable conquering this issue on your own do not hesitate to seek out professional trainers help. But remember to do your research and always be involved. Remember if your dog listens to the trainer and not you, its not really training is it? Make sure the trainer has good referrals and recommendations and uses only positive reinforcement and not harsh techniques such as dominating  dog into behaving with choke collars and such. Be as involved as you can.
