Not sure if this should go here. I am boarding a 11 month old great dane bitch until this weekend. Ivan will not leave her alone, he is obessesed with humping her. And if he cant get to her he whines and whines. As if she was in heat. Which she is not. She has growled at him to say knock it off, I've told him. But he just won't stop. Its gotten to the point where I'm seperating them. But my problem/question is. Is he going to behave like that when & if I get a liver female? And how do I get him to stop?
