6. What is Osteoarthritis?
• Progressive, permanent degeneration of articular cartilage
• aka Degenerative Joint Disease (DJD)
“OA is a by-product of the wear and tear and daily
trauma that horses experience during heavy training.”
- Dr. Rick Mitchell, Fairfield Equine Associates

7. Osteoarthritis: Some Statistics
• 60% of equine lameness problems are related to osteoarthritis,
making it the most common cause of lameness in the horse.
• Inflammation of the hock joints affects more than 50% of jumpers
and grand prix dressage horses, and requires treatment for
maintenance of peak performance.

8. Osteoarthritis: Effects
• OA is a cascading cycle of inflammation that leads to:
1. (Ligaments)
2. Joint capsule fibrosis
3. Synovial membrane thickening
4. Loss of synovial fluid

17. “Mother Nature’s Big Three”
Glucosamine is the building block of chondroitin sulfate, a specific type of
glycosaminoglycan (GAG).
Chondroitin Sulfate is not only the building block of the much larger molecules hyaluronic
acid (HA) and proteoglycan (PG) it also inhibits the effects of various enzymes that
degrade cartilage.
Hyaluronic Acid (HA) is an integral component of joint cartilage and joint fluid, providing
both lubrication and shock absorption.

28. Questions
1. Aside from jumping at shows is there a "safe" height we can jump frequently
at home for schooling that won't wear down the horse's joints too much?
2. I'd like to hear about joint care in warm weather vs. in cold weather. What
supplements should you feed at different times of year, how should you warm
your horse up, etc.?
3. Assuming the horse has been on an oral supplement for several weeks, how
long before it becomes effective after administering? What is the optimum
time to allow before working a horse after feeding a daily supplement?
4. How do you accurately evaluate the impact of joint supplements and IV/IM
medications given how subtle differences can be? What would you
recommend the owner looks for and what are good metrics/benchmarks to
watch for?
5. Are joint supplements meant to be an ongoing, lifelong basis or are they
meant to be fed on an as-needed basis?
SmartPak.com 28
29. Questions
6. Please tell us how to use MSM effectively for our horses.
7. Can you feed a Cushings-positive horse a supplement that contains
glucosamine?
8. I have a 16 year-old thoroughbred not on any supplements. He currently has
shoes all the way around and is used as a long stirrup 2'3"" hunter. He has, on
occasion, started out stiff during warm-up. Would you recommend starting a
supplement? Which one?
9. My horse is 7. Isn't he too young for me to be worried about his joints?
10. My older mare is exhibiting stiffness when ridden. However, she has had
gastric ulcers in the past and I am concerned that ingredients in joint supplements
could affect her digestive system. Is there a specific joint supplement that is
recommended?
SmartPak.com 29
30. Questions
11. If you had to choose 2-3 supplements for a 12 year-old H/J that is worked 4-5
times per week, what would they be?
12. I currently give my 24-year-old mare Cosequin. I've been giving it to her since
she was 15 not because she needed it, but so she wouldn't 'need' it later. Is it good
for her or not? She moves as though she's still 15. She is a Shire/Thoroughbred
mix.
13. Are there any scientific studies in equines to support the use of supplements
with improvements in radiographs or decreased pain ( how do you measure this in
a horse)?
14. From my warmblood H/J show horse to my tamed wild mustang who is a trail
riding horse, why hock problems and how to prevent them? I understood why my
hunter might have problems but why does a 13 year-old mustang from the wild
also have problems?
SmartPak.com 30
31. Questions
15. I'd like to hear about joint care for senior horses that are retired and being
worked vs. joint care for senior horses that are still actively being shown and
worked on a regular basis.
16. I have one mare that looks smooth when I ride her and has checked out sound
in a vet examination, but every so often I hear a click/pop sound in her hocks. She
is a 7 year-old mare and she does not act lame when I hear this.
17. I have a foal who went through OCD surgery at 11 months. He had two in his
left fetlock and one on his left stifle. All are removed and his recovery was
textbook. Is there anything I should be doing now to continue to help those joints
heal and become strong?
18. "Lexi" is a 10 year-old mare that has arthritis in her back legs and left front leg.
She is on Adequan and Legend every month, gets supplements in SmartPaks and
gets exercise every day with rest one day a week. Now she's getting stiff more
often. Please help.

32. Questions
19. How much does proper farrier work help with joints? My vet says my horse is
alot more prone to joint and suspensory damage when the farrier has not done a
good job on her feet. Please comment.
20. Should you give Adequan once a month or give the full loading dose twice a
year?
21. I'm interested in hearing about injections vs. supplements and how to work
them together.
