It's very much a mistake simply to label a dog with a resource guarding problem as 'dominant', which is a very outdated term in canine behaviour therapy. This is largely because it is just too simplistic to think that everything a dog might do which his owners disapprove of is some kind of a bid for power, especially if it involves threat behaviour. This label can also encourage owners to look for opportunities to score points back on their dog when their time would be much better spent looking for opportunities to teach him not to guard his possessions and to reward him for doing other things.
