I have a ten week old puppy that never stops biting and is now jumping up a lot and pulling on my clothes. I have tried everything. I have spent 2 weeks now using the ouch and ignore method. It hasn't helped and when i say ouch or yelp she just does it more. I was told to alpha roll her but that made it worse. She has become difficult to be around because the biting truly hurts. I have trained one GSD puppy before and it was so much easier than this. People told me to muzzle her for now but I find that way too extreme for a little puppy who needs to be able to chew her toys etc. We start puppy class at Petsmart next week but I am wondering if that will be enough or if we need some one who will work with us individually rather than in a group. I thought that because it was easy last time i could handle this job. I may have been wrong.
