He sure does look the picture of a happy dog. Beautiful!
I'm so sorry to hear about Rayden's cancer. Did the doctor say what kind he has? We lost our older dog to suspected hemangiosarcoma (all we can say for sure was that she had a tumor in her spleen and hemangio is the most common splenic cancer in GSDs) just over a year ago. It was a blow for us, but no one told her she was supposed to be sick. She was happy and comfortable right up to her last few hours when her spleen ruptured and took the decision out of our hands. I know I don't have to tell you this, but cherish every precious moment with Rayden before it his time. Our vet estimated 1-3 months by the time we found our girl's cancer but we only had a week after her diagnosis. To this day I am so thankful that I decided to take the dogs to one of their favorite parks that morning and got top watch her chase squirrels one last time.
