Hi Lynn/Loving Brownie,
I bet he's a real cutie.
You are correct that Brownie left his mama far too young. If he had stayed with his mama longer, she probably would have let him know she had no patience for his biting. She's not there, so it's really up to you to redirect that unwanted behavior
right away. Brownie needs to know he chews on puppy toys and not peeps.
I've been participating in a YorkieTalk thread, "
Teething chew recommendations please."
