Has he had a basic obedience course? I ask this because they teach a command called "leave it" that tells the dog to cease with the current thinking.
Also you might contact a behaviorist trainer to help with what is going on with your pup. Wondering if maybe your pup just does not want to share you.
I think others will come on board with their ideas.
