The poor dog was bred to run 200 yard retrieves in Derby and then move on to All-Age Stakes. He needed space, and extensive exercise, and strict training to show him how to apply his carefully-bred drive and desire.
Instead he was confined, unpredictably spoiled and then punished for doing what he was bred to do, and spent his entire life in a state of hurt bewilderment, unable to comprehend why everybody was so mad at him or why he was unable to please his humans.
I'd feel the same way if a bunch of idiots got hold of a Thoroughbred racehorse and had it hobbled and chained in a rotating pony ride at a fair.
Allllll righty, then.
