What's the difference between playing and an aggressive dogfight? Yesterday (which is a few hours ago) the two dogs were "playing" until they almost fainted from exhaustion. Now, I wouldn't let them "play" or try to hump each other, despite the fact that none of them cried even once.
It's definitely to show who's boss.
I have some pictures of the "new guy" for you to judge if he's a pure bred Yorkie, but please excuse the unprettiness of the pictures, they were taken in a hurry. |
