I agree that they probably thought that they were giving your dog a treat. Tell them that bones are dangerous for dogs. If you tell them that your dogs are on a diet they might just think that you are being a tight rear and feel sorry for your dogs then do it more.
Leanne have you ever inspected those apples? :-k I realize that I am paranoid but being that your(our) dogs are bullies and not the most popular dogs on the planet I would be afraid that she might be trying to get rid of your dogs. SInce you have asked her to stop, and she still does it I would be concerned. (I could be crazy but I would rather be safe than sorry)
