We've been having a little problem for the past 2 years with our horses that goes by the name of white line disease. We have 2 horses, one of them is 23 years old and she has never had white line until 2 years ago. We've spent over $200 trying to get rid of the white line but nothing has worked. We have used vet recommended formulas and home remedies. We live in Boise, Idaho and last winter was pretty cold and we got quite a bit of snow, so we thought white line would disappear. It didn't. Our farriers are also stumped and have suggested other formulas that don't work at all. So here is my question: have your horses had white line? And if so, what did you use to treat it? In your response, please include the following information. Is your horse 1. pastured or on dry lot 2. What type of bedding do you use? 3. Feed- hay, grain, supplements, etc 4. Shoes or barefoot? 5. Do you board or do you keep them at your house? 6. What climate do you live in? Typical weather, etc 7. Has your horse been cured of white line, and then had it come back? 8. Do you compete with your horse? This has been quite a problem in Idaho for the past couple of years so any help given here will be appreciated and spread to others via our farriers and vet. Thanks in advance for any and all responses!
