Frogs should NOT have cracks. That deep central sulcus? That's a harbor for bacteria and fungus and other junk that leads to infection. I've seen so many horses with deep-seated central sulcus thrush and owners who have no idea that their horses' caudal heel pain or stumbling might be caused by an infection in that central sulcus.
Many horses don't have strong, healthy hooves. Many have soles that are crusty and broken up. The frogs have deep cracks and flaps that harbor nasty microbes -- as well as being contracted with flattened heel bulbs. The horses land toe first to avoid pain, and that worsens the cycle because landing solidly on a robust digital cushion and well developed frog increases blood flow which contributes to hoof health.
One of the most interesting aspects of working with my rehab horse Eason is the partnership between Jamie Lyn Robbins, who trims her, and me. Jamie is rehabbing Eason's feet as I'm rehabbing her body. It's been fascinating looking at the changes in Eason's hooves over time. She was lame when she came to me in August last year, with a hock rotation so severe her left pastern would almost go to the ground. With careful trimming and bodywork and slow groundwork, she began to move better, but it took putting composite shoes on her front feet for her to be able to feel more normal. By January I was seeing positive changes, but then the ice melted and everything turned to mud and during the four days when I was gone to a dissection she went from walking and trotting and beginning to be able to canter to the left on the line to totally lame again. It turned out that not only had her heels collapsed from the wet, but she had abscesses in both her right hind and her right fore. That girl is TOUGH -- incredible at masking pain.
I pulled her shoes and did my best to treat the abscesses in horrific conditions. Jamie couldn't make it up for a month, and I tried every kind of hoofboot the local shop had available, but her hooves were so distorted nothing worked.
By March she was starting to feel better in her body but her mind was out of control. Her pen was too small for her speed-loving Thoroughbred body and she was miserable without the space to move all day. It took me a couple of months to convince the farm owner to allow me to create a track system for her, but once I got the go ahead I bought posts, tape and a solar electric fence charger and set up my primitive track with slow feed hay nets at two different locations. Her mood brightened the moment she had space to move. I'd been about two days away from hauling her back to Jamie's because I couldn't bear how unhappy she was -- so the farm owner's final "yes" was a relief to both Eason and me!
Since getting access to the track in June, Eason has been doing better overall. Three trims ago, we replaced the front shoes despite a temper tantrum on Eason's part when Jamie went to slip on the left fore. Jamie let me know to pull the shoes if Eason looked like she wasn't doing well with them -- given her extreme reaction to having it put on. So I pulled them two days later and she was surprisingly sound without them. I ordered custom ScootBoots right away and have been using them for our work sessions and lane walks.
I've been treating her central sulcus thrush forever, and it's finally starting to go away. Having her barefoot helps a lot. Her retained sole was finally separating and yesterday I watched Jamie pull away the folded over bar on her right fore and bring back the toe on her left fore. The difference in the look of her feet is incredible. I wish I had taken a picture! (I will get one.)
Even so, her hooves are a long way from looking like the hoof of a client horse I saw a week ago. I asked if I could take a picture because it illustrated a healthy hoof -- smooth, strong, with (almost) a dimple in the frog. My client, who mostly does her own trimming, has been rehabbing her horse's hooves for a full year after a terrible case of thrush, and anticipates another three years for the hoof capsule to grow out and the hoof to be properly aligned with the bony column of her pastern. She still needs to work on bringing the heels back, she says, and that line in her frog will be gone with the next trim.
Which hoof looks healthier to you?
Oh, and Eason has been doing so well on her trips out and her walks down the lane and along the busy road by herself that I am signing her up for a clinic (just groundwork at this point) in a couple of weeks! 🎉
