Boy Robin... I think we should get Tori and Buddy together and they can do that to each other all day long so that they can get a taste of their own medicine!! Bud will grab on to Sierra just like Tori is doing to Katie in the picture and has PULLED her across the ground like that!! But Sierra keeps coming back for it... so it must not be all that bad.
Dogs sure have a high tolerance for pain!!
Glad Katie put her in her place!
