Glad to hear Gonzo's getting better! Poor baby- I hope he doesn't dislike Rotties, either. My best friend's dog is a Rott/ShepX and he is just THE most submissive and friendly dog. You can roll him over on his back

Btw, it really sounded like the man was using an Alpha roll on his Rottie. If it was...Alpha Roll
I also asked a lady in law enforcement about your situation. She hasn't replied yet, but I'll PM you if she does. Good Luck! I really hope Gonzo gets better!
