Hi John. I read in the Journal today how Huck is slowing down a bit. There is a product out there it's called Ruff Greens. You just sprinkle it on top of their food and it is full of all the good nutrients and other things dogs need to thrive. It has rave reviews and it might be something you want to look into for your 4 legged family members. Many reviews claim their dogs really respond well to it. I myself am a dog lover and would try anything to keep my best friend around as long as possible. It's not real pricey and if it helps Huck it might be worth a try. Thanks for this great website John and best of luck to you and yours. Dawn
