Get some Advanced Colloidal Silver from CureZone sponsor Utopia Silver and put a couple of tablespoons or so in your dogs drinking water and then prepare to be amazed at the difference it may make. Many, many, many people have used colloidal silver for older dogs and dogs with arthritis and reported amazing results - and I have witnessed it myself.
It not only normally helps with arthritis but also often restores lost energy and youthfulness. It is not uncommon for dogs (and cats too) to become playful to an extent not witnessed in years.
