Both of our Dobies sometimes do that as they walk away from it.We have noticed all of our dogs do it sometimes. We call it revving up their motors.
Yesterday we had new neighbors moving in. Zena our Anatolian Shepard had a meet and greet with their dog Joe, an Australian shepherd.
Our farm surrounds their place and it is important for Zena to know their dog.
Joe kept coming up to Zena and then he would go off and mark his territory and then rev up his motor and come back to Zena and they would play some more. At one point she mounted him and did the doggie thing.
I don't know if that is a friendship thing or a dominate thing but the dogs are buddies now and we aren't as concerned if he should wander over into her territory.
