The younger bulldog will get better after awhile, your just going to have to give him/her more attention. I know it took a couple of weeks when my Yorkie puppies died. She has now decided that guarding me is her job, no one gets near me! She bites now too.
I'm giving her time to adjust before getting after her about the biting!
You know I have a forum a place for women to go and talk and say whatever they need to and no one judges you. It's a safe place to let down your guard and feel accepted.
