Thank You So much! I thought I just had a perverted dog on my hands, but I didn't want to punish him for it because I have learned that often the reason we humans think dogs do things, are usually incorrect.
That makes a lot of sense. I knew that his sense of smell was still okay because he's an excellent tracking dog.
And I will definately have him neutered. Not just for that reason, but because he's bothering my other two dogs. Hypersexual definately describes him!
Again, Thank you for helping clear this up!
