I totally agree that the beginning is very tough for pawrents, biting, scratching, eating poop, eating anything but gradually after five, six months, it's a relief.Great advice. I just want to add. I’ve heard it’s best to leave the puppy with the mommy and litter as long as possible. They learn a lot there, like not to scratch at you. I got mine from a backyard breeder and they pushed for me to take home the pup at five weeks! boy do I regret that. Her razor sharp teeth and paws cut up my arms pretty bad repeatedly and her jumping… it was rough. She’s five now and well behaved but it took about 2 1/2 to three years for her to calm down. I will never take a puppy that young again. Even six weeks is too young. Good luck!
