We all know that dogs are some of the most loyal animals alive. They are always by your side and will always be there to protect you no matter what. While this is all true...another thing we know to be true is that one of the hardest things to deal with in this life is to lose your best friend... This is a sad story about a police officer who recently lost his best friend. His friend's name was Bronson and he was a faithful, loyal K9. Toby Caisey is an officer and the head K9 trainer at the Boston Police Department and he had to deal with one of the most tragic losses he will likely ever deal with. The loss of his favorite pup.
