He was a big dog, 160 lbs, with a heart to match. I never was afraid if he was around because I knew he would stand between me and any danger. He was over ten years old and had turned totally gray on his muzzle. He was the best dog we ever had, was not destructive and we would just let him go out and do "his business" and he would want to come right back in to be with us. He was having problems with his back legs, they didn't always support him. I decided I should do this before we were in a predicament where he couldn't get up and I couldn't move him. If he had been smaller I might have tried to keep him alive longer, but he would sometimes lay down and whine because he couldn't get up. Sorry to babble on, just miss him already....... Thanks for letting me tell you about him.
