Welcome to Pet Talk! I am so sorry to hear of your loss of your sweet boy, Chipper--I'm sure he was wonderful. He will be running around safely at the Rainbow Bridge (they don't allow trucks there).
Pet Talk is a wonderful place to come and talk about him, I know it will take a while to get over your loss, but you have certainly come to the right place--this is such a caring and loving place. We take every loss hard here, as if they are all our pets.
Be strong, and take your time to grieve.
