Here is a picture I took of my son's dog, Apollo, just after Thanksgiving when we were cruising around in his van.
He had to put Apollo down last weekend because he had a genetic problem with his heart and was going into congestive heart failure and his lungs were filling with fluid. The pup was around 8 months old. I always have a hard time putting my dogs down, but trying to help my son deal with his loss was probably harder.
