I agree that you should let Betty see that Howard has passed. While we can never be certain what they are thinking, from experience I believe it helps. My Jack Russell will be 12 this Christmas and while he is in good health, I know that we keep inching closer and closer to the time I may have to make the same decision. He too is a champion snake killer! Hugs to you and your family in this difficult time. May Howard run free like a puppy on the other side of the bridge.
