On a happier doggy story note, I believe that I mentioned about 11 months ago that I got my Aussie/Rottie girl, who was 7.5 at the time, stem cell therapy surgery. She has arthritis and frankly the hips of a dog like five years older. The vet pulls fat from the shoulders, removes the stem cell, makes a milk shake, and then injects the back knees and hips. Well, 11 months later, her arthritis and hip dysplasia have gotten no worse, and she's needed Rimadyl for one day to deal with the pain/inflammation of running around like she used to 3-4 years ago.
If anyone has a dog or knows someone with a dog who's suffering from arthritis and/or dysplasia, then I definitely recommend looking into the procedure. It's not cheap. Probably about $2000-$3000. For that price, they'll 'bank' another dosage for injection once the initial injection wears off (anywhere from 1-3 years, but typically 18 months) and charge $200 a year for storage; you'll have to pay for the next injection, but I think it will be about $500. Anyway, obviously not cheap, but it definitely is a lot cheaper that other surgical options.
