5 month old puppy jumping and biting....HELP!!!!!!
We got our first GSD at 8 weeks of age. Her name is Minka and she'll be 5 months old on the 26th of this month. She's an angel inside the house and the best puppy ever, BUT, when we go outside with our two older Labs, she lunges at all of us and shows her teeth and bites us.
She hurt my 8 year old son yesterday biting him. I've tried everything and nothing is working. We love her and want her to be as gentle outside and she is inside...advice PLEASE!!!
