We've been taking Midas out to the dog park for awhile now, and lately he's been getting VERY protective over toys that we bring for him to play with. It doesn't even have to be his toys, if he finds any toy on the ground and another dog comes close to it, he will go after the other dog with intent to bite. Right now, we warn other owners about his behavior, and when it does happen, we try and catch him in the act as much as possible. We grab him, give him a firm NO!, and take the toy away and then when he gets his mind off of it, we let him go. So far this is a quick fix but we are definitely looking for a long term solution.
So, we are needing any kind of method that will help stop this behavior. Any ideas?
