Further explanation about that scene. It's still on my list to see.
Given that I've had to put a dog down and my current 11 month old pup is named Bailey, there is no way in hell I plan to have any part of watching that movie. However, from reading Dennis Quaid's report on the situation as well as other folks involved, and given the timing of the video release, I suspect footage edited for shock value / blackmail attempt unpaid is the likeliest thing.
