i think dogs know who the “Pack Leader” is without being a little “mean”.dogs are very smart,and without the “Pack Leader” there is no food,water or shelter. not only that,dogs want to please their owner. dogs do communicate its the owners that dont listen and if a dog is being bad its because hes trying to get your attention and tell you something. i have a chow thats 15 years old and a pit that is 6yrs. old they dont need to be put “in their place” because they know without me they dont survive! i even allow my pit to sleep with me. sometimes i think he’s the boss!
