Well moxy what do you get out of it? Is it an unconscious urge to move the flexible ears around because of the way they feel or a primal alpha, “you’re my bitch” thing? If it’s more along the lines of the first one then maybe get some clay, sillypuddy, or other sculpting material and play with it. If it’s the second, maybe try some sort of physical activity like martial arts or wrestling or boxing to have that outlet.
But @Moxy, please qualify this a little more. In what manner do you pull, are you hurting the dog or just playing with it’s ears? Or is it the compulsion that you are talking about? You want to yank your dogs ears, what would you get out of it?
