A bunch of Disney-esque forest animals were preparing themselves for battle against humans. I was watching try-outs for their army, they looked sort of like the Reindeer Games. They were using a series of dog training manuals to train these creatures. Most of them were squirrels and other rodents, only 3 of them were dogs. One dog was the son of two famed soldiers, so he felt the need to impress everyone and prove that he was just as good. Unfortunately, he'd failed all of the animal intelligence tests in these books. The leaders gave him a chance anyway, and his incompetence resulted in horrific failure and the death of 2 other animals.
