Rethinking how to treat laminitis

Kurt comparison 2 21 2015

 

My white horse, Kurt, had a bout of laminitis in January 2015, and it made me rethink the treatment process.

Traditionally, Kurt has been my horse with the fewest problems. Despite his feet being white, they’ve been tough enough to trot on a gravel driveway. Kurt has always been barefoot, even when showing. He suffered a suspensory ligament injury in 2003 that ended his career.

Once he stopped exercising, his feet started having problems. Mostly abscesses. Not big hoof meltdowns.

His feet have been getting more stretched out over the last decade, and my longtime farrier did not seem interested in embracing the principles of farrier Pete Ramey. Ramey advocates a shorter foot from front to back. Ramey’s ideas have been my focus for the past two years. Based on my experiences, I would suggest that the horse owner and farrier have to be on the same page, or there will be tension. I took over trimming Kurt’s feet completely after his last farrier trim on April 4, 2014. You can see the foot I started with in the photo at left above.

By January 2015, I had made a lot of progress in getting rid of the flare on Kurt’s feet, but not enough.

On the morning of Jan. 5, 2015, a morning when the temperature was near zero, I noticed that Kurt was shifting his weight a little. When I got home from work that evening, he was totally lame in three feet, carrying most of his weight on his right hind. His left hind had the most pain, and it was burning up. His front feet were also really sore.

I assessed my options:

Option 1: Icing. Laminitis researchers tend to favor icing the feet and have plenty of research to show icing stops the laminitis process. I believe icing works well on a horse’s first case of laminitis, but it has been useless or painful for my chronically laminitic horses. And icing wasn’t even a choice, given the weather.

Option 2: Bute. Kurt had a very bad case of colic after he was given a gram of bute with his dinner in October 2014, likely the result of an ulcer, and I thought I would lose him that night. We decided that night that we’d go without bute, no matter what the pain. So no bute.

Option 3: Supplements. Veterinarian Eleanor Kellon has written a very interesting article on winter laminitis, and I considered if we wanted to add some supplements to Kurt’s diet, but buying those supplements would have been at least a week-long process, and I needed to do something immediately.

Option 4: Trimming. If there’s one thing I have learned in dealing with laminitis since 1998, it is this: The time to trim a laminitic horse is immediately. I don’t wait a day to see how the horse is doing. He’s in trouble because the way he’s loading his feet is painful. I will always take the risk of making a mistake in my trimming rather than doing nothing because doing nothing gets us nowhere.

In 4 degree weather that evening, I headed out to the shed with my belt sander, not fully believing the sander was going to work in that weather.

I was able to trim all four feet, even with Kurt in pain. I did a little trimming each night over the next three nights, though if I had to do it again, I would try to do it all the first night to provide more relief immediately.

Lowering Kurt's walls has allowed the frog to carry more weight.

On each foot, I trimmed the walls and heel to get Kurt’s frog more contact with the ground. This unloaded Kurt’s walls (he has a big frog that does make ground contact), and I shortened the foot from front to back by sanding the hoof wall around the front in the same manner that a farrier would just nip that off. Then, I beveled the toe from the solar ridge forward so the tip of the toe was not making contact with the ground.

The solar ridge concept is one offered by farrier Maureen Tierney, who says this ridge shows us where to trim. The horse develops this ridge on its own, even in a stretched out foot.

If you look at Kurt’s left front foot in the image from April 27, 2014, at the top of this post, the solar ridge is clearly evident as the outline where Kurt is loading the foot. The flared wall to the outside likely was uncomfortable. If I had trimmed his foot to the solar ridge originally, Kurt probably would have done better over the past year. Instead, I chipped away at that flare a little every weekend.

The end result of the Jan. 5, 2015, bout of laminitis was that Kurt got better each of the next three days (Jan. 6, 7 and 8), and he was sound by Jan. 9 and able to walk soundly over frozen ground. The low temperature overnight on Jan. 8 was 3 degrees.

We’ve had several more overnight lows of zero in recent weeks, and he’s remained sound. I trim him every weekend to keep the walls from growing out.

So what did I learn?

The core thing I accomplished was unloading his wall. I did nothing else. He was happy in three days with no bute.

When I look back at my late mare Angel’s bout of winter laminitis in 2004, her treatment involved putting her in a stall, shoeing her with reverse heart bars shoes, spending thousands of dollars in vet and farrier bills, changing her diet and testing her hay, etc., and she got worse, ultimately developing horrendous abscesses.

When I thumb through photos of Angel’s feet over the last few years of her life, her toes were way too long. Not ski jump long. Just way too long, which applied pressure to the tip of the toe every time she took a step.

I think we make trimming the laminitic horse too complicated. And correct trimming should start before the horse becomes laminitic.

The frog should cover most of the bottom of the foot and be in contact with the ground, reducing the pressure on the walls. And the toe needs to be trimmed back as far as possible and beveled.

I have never met farriers Pete Ramey or Gene Ovnicek (another proponent of the shorter foot), but I want to thank both of them for getting their ideas out to horse owners. Also, thank you to farrier June, who wrote me an email encouraging me to start reading Ramey’s and Ovnicek’s websites.

I’m sure Kurt and Robin, my last surviving laminitic horses, would be dead if I hadn’t embraced these farriers’ ideas.
