Hm, it sounds like more than one problem. He sounds insecure, hence the barking, and he is also resource guarding. Even very sweet, secure dogs can have resource guarding issues. One of the easiest ways to prevent resource guarding is not to give him things he wants to guard, like bones. You can also Google this behavior - there are other techniques, like teaching him to "trade". I've also seen the book "Mine" recommended (you can get it off amazon).
The barking is probably a separate issue, and could be caused by a number of things. If it's to the point where you might give him away, I would strongly recommend a trainer or a class - just make sure that they come well recommended, since anyone can call themselves a trainer. |
