A cop just wanted to play one last time with his dying dog and reminisce about their old days together before veterinarians at a facility in Mexico laid the dog to rest.

Flora was a retired K9 who had been diagnosed with a form of terminal heart cancer after years on a local police force.

As the German Shepherd stood on top of table on her four paws, the young man took a padded arm sleeve protector and slid it over his left arm.
