I'm sorry to say that's not true.

Wish it were!

^^ agreed...not true! I've seen it on any color feet.

humm....well I researched the heck out of it when my guy had it and everything said "only white feet will get this " maybe you had something else... not scratches ???

No, I have most definitely had (start to finish) scratches on dark legs. As many as light, easily. It's a bacterial infection... and while less pigmented skin may be slightly more susceptible, it happens quite often on dark legs.

Nope. Had a vet look at my mare when she had scratches... she only had it on her dark legs. And yes it WAS scratches. Old wives tale that it only occurs on white legs.

Or maybe it was that white legs/feet are more "prone" to it ??? Now that I think about it I believe that is what I read. It usually starts with dry skin or a cut/abrasion of some sort... and then it gets infected with the mud... funny how my guy's hind feet are white and only got the scratches...the dark front feet were standing in the same mud... almost like photosynthesis... sensitive skin back there....

Not necessarily true. Yes, they are more prone to it, but my chestnut with NO socks got it last year.

This tends to show up on the white areas of the lower legs and face.

Secondary photosensitization in a horse on pasture: presumptive
alsike clover poisoning

Sarah Hann
November 4th, 2009
Preclinical Advisor - Dr. Marnie Fitzmaurice
Clinical Advisor - Dr. Mary Smith
A 2-year old, gelded, Chincoteague Pony was presented to the Ambulatory Service on Friday,
5/29/09 for lethargy, anorexia, and mild colic of one-day duration. The colic was characterized
by repeated episodes of recumbency without rolling. On presentation, the gelding was recumbent
and lethargic with a flaccid lower lip, a deviated muzzle, and decreased tongue tone. The pony
had a decreased menace response with a normal pupillary light reflex but showed no evidence of
ataxia or decreased proprioception. The gelding was afebrile and eupneic, with normal gut
sounds in all four quadrants. Primary differentials at the time included trauma or colic with
subsequent facial nerve paralysis; however, causes of brainstem and cranial nerve signs could not
be ruled out due to the presence of decreased tongue tone. The gelding was given a dose of
flunixin meglumine and the owners were instructed to monitor clinical signs. The following day,
Saturday 5/30/09, the Ambulatory Service was called to evaluate continued signs of mild colic.
On presentation the second day, ptosis was present OS. The muzzle deviation had resolved but
the white snip was swollen, edematous, and blistering. In addition, the gelding had icteric
mucous membranes. The pasture was examined and found to contain alsike clover, Trifolium
hybridum. Blood was drawn that day and evaluated on Monday, 6/1/09. Significant biochemical
abnormalities included increased aspartate aminotransferase, sorbitol dehydrogenase, glutamate
dehydrogenase, alkaline phosphatase, and gamma-glutamyl transferase as well as increased
direct and indirect bilirubin.
Treatment was instituted to support liver function and palliate secondary photosensitization. The
gelding was removed from the pasture containing alsike clover and housed indoors during the
day to avoid ultraviolet light exposure. The pony received anti-endotoxic doses of flunixin
meglumine and a course of trimethoprim sulphamethoxazole; blisters were treated with zinc
ointment and triple antibiotic. Hay was provided ad libitum and supplemented with a high fat,
low carbohydrate grain with the addition of 2000 IU of vitamin E daily.

Secondary photosensitization
Hepatic encephalopathy
Hepatic dysfunction

Oops, meant to post an update..
No pictures!

But I followed some of the directions and it's cleared up like crazy!
We will see how it does as its been raining off and on today and I threw him outside...

But I really do think it's related to the moisutre though..
I didn't clip his legs, no way to but oh well they're not that curly yet anyways.
