The pooch has not sprained his leg during his boisterous shenanigans as I thought he had. Rather, it is bone cancer. In my 5 year old pup! My heart is shattered! It’s terminal and fast paced and there’s nothing we can do to stop its progression to his lungs. I’m so sad it’s hard to put into words. I thought he would be with us for a good many years yet, with his mischief, enormous size (and personality) and extremely quick brain. Bone cancer is apparently agony, and so we now have to decide how long is too long to keep him on a steady stream of morphine and anti-inflammatories. The hardest decision I’ve ever had to make.
