I've posed this question on a couple of debate/question and answer threads and haven't gotten a response, so I thought I pose it here as well...
The reason Frosty blew up with me when he tried to power out of the 1st barrel is because his hocks are sore. I noticed it not long after while watching him gallop around the yard and I have been hesitant to run him since then. It's not fair to him.
As an insulin resistant horse, Frosty is sensitive to feed through glucosamine. A little doesn't bother him, but enough to actually do his joints any good affects him.
I was initially thinking that I would just take him back to my vet and have his hocks injected, but I have about $300 worth of chondroprotec (Adequan substitute) here that I 'could' start giving him in lu of injections, to see if it would help. In fact, intramuscular glucosamine is supposed to be more affective for the spine and hips than feed through glucosamine and that would also benefit Frosty.
My vet was a bit non-commital about whether the im shots would/could affect Frosty the same way the feed through glucosamine does and simply said that 'studies show' that im glucosamine is not as apt to affect IR horses as feed throughs are.
I was just wondering if anyone has had any experience with giving an IR horse intramuscular glucosamine?
