So, in other words, in regard my 2nd to last post, I do not believe that dogs living in our homes have it in mind to raise their position in a hierarchy-like status, to become as an alpha wolf in a wolf pack when they live with a different species. I do not equate misbehavior, including aggression with dominance. Dogs do what works and if it works to achieve what they want, whether it's to pull on a leash, to be pushy about food, to bite someone to make them back off.....it's not status seeking behavior because they don't need it. Its about reinforcement. Naturally dogs want to hurry and go for a walk. We walk too slowly. They're hungry and want their food in a hurry. They have a fear or defensiveness, so they bite. If all the responses they've gotten for these behaviors have worked...they've been reinforced for them, they will be repeated. If doing those things does not work for them, if there is no reinforcement or payoff, those behaviors will cease.
