Dogs that do not relinquish toys or objects to owners. If the owner tries to take the object the dog growls. Often the dog will present the object for play, and then strike when the owner reaches for the object. They may solicit attention and then respond to the attention with a challenge.
This aggression type may be part of a control complex that can include other kinds of aggression such as owner directed aggression, territorial aggression, etc.
