My grandad had a dog that loved to hunt rabbits (and racoons too). His name was 'Ol Blu, no reason why. He used to ride in the back of a stakebed truck. One time a stake popped out on a bump and landed square on his tail. Broke it like a twig and once it healed his tail made a 90 degree turn about half way down. Hillarious dog, not brilliant but brave. He ended up slowly being able to see less and less. He locked on to a rabbit one day in the yard and chased it like he was 1 year old. Chased it right into a wood pile. The rabbit ran into a hole between logs in the pile. Blu ran head first into the wood pile going full bore. That was it for 'Ol Blu. Killed by a rabbit, irony.
