Am I the only one thinking that this is the work of a cruel A-hole?
It looks like the dogs leg is being move by a string or something....
OMG! Really? Now that you mention it, that lef is not moving in a natural manner. How effed up. 
I think so, it just doesn't look right, plus I have 2 dogs at home who are possessive like that over treats so I've seen how they normally react...
The cgi'd the string out, mayhap.
