I spent one of those mornings with our 11-week old puppy that made me sit down and google his issue --- nipping, biting pant legs, jumping from behind, etc. Your site came up and I read your entries with interest and hope because it appears you have experienced the same and overcame the issues. I have been receiving different advice from different sources (vet, trainer, breeder, etc.), but I am anxious to know what you did to handle the situation. Any advice or guidance would be appreciated. Thank you.
