Our dog was pretty dumb as well. We have a line that we would hook her up to, it's run to the shed, which is about 100 yards away from the house. We live near a field, so rabbits are pretty common. Whenever there was a rabbit, we would hook her up, she would chase them. Now mind you, these rabbits were more intelligent than your average, and they learned EXACTLY where the end of the run was. Our dog would reach this point of no return, at full speed, and she would get about 5-7 feet of air... it was pitiful. Wish i'd gotten it on tape before we had to put her down. oh well
Anywho - video reminded me of that - funny stuff.
