We found Deramaxx (a NSAID) to be a near miracle drug for our near retired police dogs. These were dogs with problems that Rimadyl did not touch.
You have to recall that these were some very valuable and proficient dogs in their glory years. Our senior dogs have finally figured out all the tasks, have street smarts, and have slowed down enough to run a very methodical and accurate track. It's an absolute shame when these great years are cut short by physical issues.
We generally have to retire dogs due to age related arthritis and skeletal issues. We can generally see the end coming and can predict within 6-12 months of when a dog will be finished.
Using Deramaxx has consistently tacked on 1-2 years of very good service years. While we reduce the amount of tracking, jumping, and apprehension work for our senior group -- the dog's still perform in very challenging conditions.
The only downside for us is cost. (Perhaps $100 a month).
I'd venture that we've had 6-8 dogs on it over the year and it has been by far the most successful therapy we've used. Prior to Deramaxx we tried several other drug therapies, canine chriopractic, and acupuncture. Again, the dogs are very valuable.
Depending on your budget you may find this worth a try. For me, the results have been nothing short of a miracle!
Best Wishes,
