I know that feeling, Dana my Rottweiler done me that way, nothing like boucining across the yard with you hand caught in the collar while trying to hold the big giant back!
LOL Never happened to me yet...Jasper's still small

I'd love to here more about Dana, I love rotties, (I love boxers too..of course, but loved rotties first) I would have got one, but my parents are scared of them lol, bad experience....but thats only one, anyway I'll get one when I move out
