This kind of things probably happens all the time in families with mixed pets. Some animals from different species respect each other, love each other, and live every day sharing the same house, attention, and love of their human owners.
But we probably could find competitiveness in this mixed families. It would be naïve to think everything is sunshine and flowers; and when they both try to be the favorite of the human, a lot of funny things could happen.
In this video, we have one of those families with a disobedient cat and a very diligent dog. The owner wants the cat inside the house, but he has other plans. So she appeals to a helpful dog to leave things clear.
It’s obvious this is a very serene cat if he lets the dog treat him like that.
