Hi, I'm new here and I'm in desparate need of some help. I have a 4 or 5 year old beagle who's been getting aggressive for the past year or so. I know that he has a problem with barking at strangers, but my biggest problem with him is if I give him a bone, he will growl and try to bite me if I get it. If he doesn't get a bone, he's pretty much a normal dog who obeys me most of the time. He still needs some work on "come" but otherwise he's fine. I don't know if I should get a trainer like Bark Busters to come and help since I only have this problem when he eats bones. If he eats his kibble, my dog has no problem sharing.
