Ok thanks! Now let me ask this. I have a male now who is neutered. He does hump sometimes but nothing major and I haven't "seen" him mark anything. Is it different if they do get bred? My yorkie was fixed right after I got him (at whatever the appropriate age is).
I did just ask the owner of the pup and she does not know his blood lines. She says he is AKC registered and Full blooded.
