I think it's fine if you link to craiglist, the pic is already around on the internet and not private.

Shire, so huge draft, means she's putting a lot of weight on those pasterns... if you decide you love her, have your vet check her and tell you an honest opinion. Of course it is you who'll pay the vet, even if you decide to not buy.

I am sorry to see people linking the dsld page but I knew it would happen. My personal opinion is that a good many "dsld diagnosed" horses are actually horses that have suffered injuries and were left untreated. I think my stallion was one of those.

For what it's worth: Dr. Kellon's "study" isn't a study at all. It has no parameters, no study criteria and no control subjects. It's simply a bunch of people feeding their horses an herbal supplement that they buy from the women who run the dsld/equine yahoo group.

Posting that link was for informational purposes only, I believe the OP saw it that way. If you have better, proven sources, by all means, educate us. After all, we're all can only suggest based on our own experiences.

Peruvian- my TB mare has DSLD. There is no way this disease is related to an injury. Dr. Kellen is a fraud- using her yahoo website to sell some herbs with little to no scientific backing and no controlled studies.

The University of Florida and the University of Georgia are both studying this disorder. I spoke to the pathologist at you of G and they believe the disease is systematic based on tissue samples. Injuries usually occur on one leg- not both or all 4 as is with this disease. Another researcher is working on determining the genetic basis so they can test for it. So far they have narrowed it down, but they still have a long way to go.

These horses do not respond to stem cell treatment, shock wave therapy etc. Best guess is that it is similar to Ehlers danlos syndrome in people.

Sadly people are continuing to breed these horses. I saw a WB stallion the other day with an obvious case. It is even found in some very popular TB bloodlines as well (Mr. Prospector).

I highly suspect Mr. Prospector had the disease as his racing career was ended due to ankle problems, his pictures show dropped ankles on both hinds, and at least one of his offspring developed the disease as well.

I want to reply to your post but I am going to have to do it a paragraph at a time. Some of the information I have is on my old computer and I will have pull it out of the closet to access the information.

If you are at all familiar with the dsldequine group on Yahoo you know that the main target of that group is the Peruvian Horse. These people claim that dsld is prevalent in our breed, that it is genetic, and that "no Peruvian bloodline is safe" from it. I have had Peruvian horses since 1995 so I am no stranger to this group or to the stories, rumors, and theories that have been posted there.

Contrary to some of the claims being made, nobody really knows what dsld is, what causes it, or if it is even the result of a disease. There are a lot of self-proclaimed "experts" out there - like the women who run the dsldequine yahoo group - who claim it's a genetic disease. Research has been underway for over 20 years. To this date the research has not identified any gene(s) that cause dsld; so there is no genetic test for dsld.

The research that has been done has led to contradictory results. Research done in 2006 concluded that dsld is an "abnormal accumulation of proteoglycans" in connective tissues. Further research done in 2009 by a group of medical doctors and veterinarians "found no evidence that DSLD is a systemic proteoglycan deposition disease." (I have links to both studies if anyone is interested.) Some of the "control" horses in the 2006 study had as many proteoglycans in their cells as some of the "affected" horses but the research completely ignores this fact.

There is a test that has been touted as a way of identifying horses that are in the early stages of dsld. The "nuchal ligament biopsy" is supposed to identify horses with excess proteoglycans in their cells. But if the 2009 research is correct and dsld is not a proteoglycan accumulation disorder, then testing for excess proteoglycans is useless. Further, nuchal ligament biopsies have resulted in false positives as well as false negatives, so the test itself is unreliable.

A nuchal ligament biopsy involves slicing into the ligament that runs along the crest of the neck to take tissue samples. The nuchal ligament is a big ligament that supports the head and neck and is constantly in motion. After being subjected to this test many horses have had problems healing. One woman on the Yahoo list who had this test done on her Paso Fino said her horse's neck had become infected and the horse was still having trouble healing 6 weeks after the samples had been taken.

I realize that it is a controversial diagnosis. I believe that there is a definitive disease process going on, even if it is not totally understood yet.

Why else would a horse who is not in work, within weeks have both hind legs swell up and drop? First one leg, than while the horse is rested for the first leg, have the second leg swell and drop?

Obviously it isn't injury related, so that means you have to have some sort of disease process going on. My horse was ultrasounded after the first leg swelled up- there were no tears or holes evident on ultrasound. Doesn't that exclude injury? Usually with injuries you have obvious tears on ultrasound examination. Now the ultrasound did show thickening of the ligament.

I don't see the point in doing extensive diagnositic tests. To me any horse who has dropped pasterns in more than one leg, probably has DSLD. Dropped pasterns, enlarged ankles, and a change in hind end comformation, all suggest DSLD to me.

Although a genetic marker hasn't been identified yet doesn't mean it won't be with further research.

"The genome scan identified five chromosomal regions where statistically significant differences were seen between affected and unaffected sample populations that could be indications of linkage to DSLD. Those chromosomes were: ECA 6, 7, 11, 14, and 26.

Further research needs to be conducted especially on ECA 6 and 11 since possible candidate genes are located in those regions based on the human comparative map.
