Please............anyone who can offer advice for arthritis on dogs would be GREATLY appreciated!! My sweet Blitz (you can see his picture on my avatar) has arthritis in his back legs and it is killing me to see him in so much pain!! Any advice would be so greatly appreciated!! He is 8 years old, somewhat overweight and very stiff in his hind quarters. I am afraid to walk him anymore for fear that I might make his condition worse. Please, if you know of any remedies or advice, I would love to know what I can do to help him. I've already experienced putting down my other Rottie due to cancer and arthritis and don't want to lose Blitz in 2008 the same way. Please help if you can!!
