Your dog is not trying to dominate you
From SaanichNews.com:
The concept of an alpha wolf/dog has been debunked the dominance training model needs to be eliminated. I often get calls from dog guardians who believe their dog is attempting to dominate them or establish themselves as the “alpha” in the household. They describe behaviours such as not letting people on the bed, sofa or into vehicles. They assume these actions stem from a desire for control.
The concept of the alpha dog is a misinterpretation rooted in outdated wolf research.
