I have recently adopted a three month old German Shepherd puppy. He has recently recovered from have the parvo virus and is normal again. I have noticed one problem though. Ill be wacthing the dog (thunder) and he will be laying down perfectly relaxed. Then suddenly he will get up and run around growling and tearing stuff. It is like a sudden rush of energy. When I try to calm him down he bites me! Any idea what this is?

Whoops...

I believe that is a strong sign of your baby's recovery! While training is very important, that sudden rush of energy can be very common in puppies. I would address the biting FIRST. My 1yo pup still gets the "crazies" but is not destructive and I do not become a victim any longer.
The biting is actually was very easy for me to deal with. However, I must say my dog has some sound sensitivity with worked in my favor.
My Rotti mix was a biting maniac for a while as a pup. My trainer suggested I yelp or yell "OW!" every time her teeth touched my skin. I would yell really loud all the sudden and it really startled her. Within a week she had stopped. She will only gently mouth my hand when playing now, she is very cautious. While leadership is key, as far as biting - this DOES works! Puppies play very rough with each other and with other dogs, when the pup hurts another they yelp loudly. Play will usually come to a complete stop for a few seconds and then resume at a lesser degree. They are learning limits and about appropriate behavior. Of course, you need to get all your friends and visitors to go along and yelp as well! ;)
