Global Healthy Fall Frogs

I have been grinning over super nice frogs for the past few weeks and started taking pictures of them to share. Most of these frogs shed out in late August or September and are coming back in great now. Some are well developed, others are still immature. They all look super to me.

These case studies are horses with healthy frogs along with a brief bio for each horse. I will try and update this page if interesting frogs come up.




Gabby's rear feet, trail ridden 15 to 30 miles a week usually barefoot behind. I wish I had left a little more heel height. His frog shed 4 weeks earlier so this frog is immature.

I sometimes spend as much time on the frogs's as I spend on the rest of the hoof when I trim. I nipper the core out of the central sulcus, nip any flaps, open cracks up and treat thrush with Usnea tincture if I see any.

If I find bad thrush, I nipper off as many flaps as I can with Bonsai tools.

How aggressive I get opening up cracks depends on the season, conditions, environment and how close the frog is to shedding again.


Why I Wrote This Article

I moderate the Whole Horse Health Yahoo list . We had a thread going on in September or October on Thrush, and I sent in a post that included this comment:

"Everyone wants to ignore or downplay the impact of thrush. The expensive A Circuit Jumper, case study below, was seen by many top vets and vet clinics, was shod by “the best” and was finally given away, free. Great story on the consequences of ignoring our horses pain…

I got the following post from a moderated member whose posts had gotten tiring for many members. She had made prior comments stating that thrush, essentially, isn't really a problem. I decided to hold this particular post back. Still, I was dismayed that an experienced trimmer could be so willfully blind to something that I ***know*** is a serious problem!

...... I don’t see thrush in these feet and to be honest the shoeing and trimming underneath it doesn’t look poor either.

.... So not to discredit anything you are doing, the trim looks great btw, I just don’t think the claim of thrush RX cured this horse is accurate and it could be.

This horse, picture below right. had thrush that was so painful he threatened to kick when the foot was cleaned, his frog and digital cushion were extremely sensitive, and the hoof pick sank 1/2 inch into the deep crack that penetrated his digital cushion. You can see the deep crack on the Freedom case study that she referred to.

When I look at this case study, I see nothing but thrush and a horribly unhealthy frog!!!! The fact that someone who claims to trim 200 horses in wet east coast weather could see this and not recognize thrush? I was blown away. Appalled. A good trimmer needs to know the many components of soundness.

This was one very unhealthy foot on a very uncomfortable horse. The horse didn't want us handling the thrushy foot at all; he pulled his leg, threatened to kick and refused to stand still.

We did clear up the thrush after a few months of treatment, and the horse regained total soundness, but he later coliced, twisted a gut and had to be put down.

So my message is "Just because someone has a well known name, credentials, a web site, trimming DVD's ... it doesn't mean that they know everything."

Myself included! I still have a lot to learn. We each need to think for ourselves, professionals and owners. Question whatever person you call an authority. Question your own assumptions. For the horse.

We each need to learn the difference between painful unhealthy frogs and healthy frogs, and how unhealthy frogs affect movement and comfort.

Don't settle for unhealthy frogs!! If your trimmer can't figure it out, you may have to. Unfortunately Certification or being on some online list doesn't mean a trimmer is a guru about everything.

Frogs are important, no matter what climate you are in.

Do YOU have healthy frogs you want to share from your area?

I really want folks to get this deal about the importance of healthy frogs, so if you have healthy frogs to share, email two to three pictures, your area and a brief bio to me at healthyhoof@comcast. net. See Asa's example, below, to get an idea of what to send!

When I get enough pictures from different areas, I'll put it on a separate web page.

To see Healthy Frogs in perspective, you may need to look at unhealthy frogs first.

Four or five years ago, I was trimming at a clinic in Lake County, Ca, and someone asked me if their horse had thrush... the frog was "okay" but had this black greasy sulcus crack, and it was really tender.... I wasn't really sure!

After that, I started looking at thrush seriously. I talked to Pete Ramey, and he suggested Pete's Goo (triple antibiotic ointment and athletes foot cream, see Thrush Treatments page )

When I realized that perhaps a third of my client horses had thrush to some extent, I was determined to turn that around, and it's taken time and perseverance, but I have.

The following symptoms often tie directly to thrush:

  • Chronic high bar, heels & retained sole growth to relieve pressure on frog
  • Medial /Lateral imbalance ( Wry feet)
  • Base-narrow stance &/or sore shoulders
  • Ulcer horses often have thrush, and vice versa
  • Horses that won't walk-out going down-hill


Freedom - This horses real name was Liberty, and he was a valuable A Circuit Jumper who was almost euthanized because he had thrush. A friend rescued him, we cleared up all of his problems, and he unfortunately coliced and died in early 2009. Great story.

Thrush - Pictures of thrushy feet, more information on thrush.

Samson and Medial Lateral Imbalance - had severe thrush for long enough that his coffin bone was modified

Thrush Treatments a few of the many ways to treat thrush with comments on things I DON"T use, including bleach, thrush busters and coppertox. Other stuff, like Dry Cow Teat medicine, Albadrys and colloidal silver work too, I've just never used them. I try to steer clear of anything with penicillin (Dry Cow Teat medicine & Albadrys ) unless I absolutely need them because I worry about ending up with resistant strains of bacteria in my horses feet!

How My Clients & I Keep Frogs Healthy Today (November 1 2009)

Getting a good heel-first landing impacts how healthy the frog is because it results in optimum blood circulation. A horse can't land heel first if the frog is a source of pain. It can be a vicious cycle!

I strongly recommend that clients feed low carb forage and pellets, and to keep horses off stressed or rich pasture.

Great frogs don't happen overnight! When clients resist cleaning and treating frogs or resist dietary changes, I take pictures of feet, repeatedly point out diet-related frog separation and thrush (along with the associated wall and white line separation) and other signs of mild laminitis that may be part of the problem.

I also recommend that clients provide a dry or drained place for horses to stand in wet weather, and all of them have done this. I trim all flaps and grooves regularly, keep the frog neat and look for thrush during each trim. Clients scrub feet with Dawn Dishwashing detergent and a brush at any sign of thrush or when feet start stinking, and many cut off frog flaps that appear between trims. That isn't necessary because I do a thorough job when I trim, but once clients recognize how important a healthy frog is, they like to participate.

We use Usnea, Pete's Goo, Oxine and Dawn to control most thrush. See Thrush Treatments for more treatments!

DIET AND FROGS - Go for low-carb forage & pellets, & watch the pasture!

Diet has a ***huge*** impact on frogs, soles and walls... diet is probably one of the most important factors along with good frog trimming.

Most of my clients follow my advice and feed low carb forage and pellets, many balance their minerals, and most are very careful with stressed or rich pasture. I see diet impacting EVERYTHING now, from ulcers to skin problems to wall attachment.... most of my clients follow my recommendations so I get awesome frogs.

Thrush Elimination ...Whose Job Is It?

My opinion is that it's the Trimmers job to inform a client when their horse has thrush as well as to clean up the frog so that treatments will be more effective. If a horse has a super painful frog infection, the owner may need to soak or otherwise treat the thrush so that the trimmer is safe working on the frogs. I use Usnea Tincture to help relieve pain in frogs I'm trimming, but if the infection is serious, it may not be adequate.

Owners need to be responsible for diet changes, if necessary, and for treating the thrush aggressively enough to clear it up.

Trimmers only see a typical client horse for 20 to 60 minutes a month, not enough time to be solely responsible for frog condition... owners need to actively participate! Learning what remedies are available and using them, talking to your trimmer about alternatives...

I have dealt with many horribly thrushy frogs over the years, and they CAN be cleaned up,

A Comment About Fall & Winter Bars

When you look at these pictures, you'll notice a slight bar ridge on most of the feet. I make sure bars aren't loose and shedding, ensure that they are passive to the wall, but leave a bit of bar ridge, especially when its wet and muddy.

Why? Those bars provide **great** traction in mud, and at this time of the year, when the frogs and sole calluses have just shed, they provide a bit of support for the interior of the hoof as well.

On Gabby's pictures, his soles are thinner than optimum and the bar is coming up to provide a bit more protection. The hoof is an amazing thing to really watch.

Gabby aka Gavilan

Gabby is my teen-age Arab gelding (born spring 1994) and he's been with me since he was weaned... he's my "magic horse", my soul brother. He has 900 AERC miles (we need to correct a few mis spelled name records!) but most of my riding is trails, for the sheer pleasure of it.

He was shod at 4 years when I started really riding him, and was shod on the fronts until 2003, when I pulled all of his shoes for the first time. He had occasionally gone bare behind. Gabby's the reason I went barefoot, and the story is funny.... Gabby & the Farrier


Gabby loves life and is always "smiling".... I adore him and he knows it!

Gab lives on a 20 acre pasture 1 hour north of San Francisco. The mixed pasture was a dairy field at one time, and is covered in large patches of water during the rainy season (approx. late November to May), and while much of the rolling but mostly flat pasture is not in standing water, much of it is covered through the whole rainy season. When the boys come running in to see me in the winter, their feet throw up water most of way! The do a lot of wading, and it doesn't bother their feet or frogs at all.

The pasture forage does create problems. Gabby and my other two retired arabs lived off pasture forage alone June 2008 until October 2008. From October 2008 to June 2009, I usually let them on the pasture muzzled. If it got below 40 degrees at night, I pulled them in and fed them grass hay in paddocks. By the end of spring, Gabby's feet were okay but the wall integrity was soft. It wasn't the water in the field, it was the stressed grass.

This year Gabby is coming off pasture any time the grass gets the least bit rich because I want his feet to stay durable. My remaining aged gelding, Shatirr, will go out on pasture more because he needs more calories, but will be muzzled. I had to put my other sweet old guy, Kadence, down on July 7 2009... Sad day.

I trail ride Gabby, mostly on very rocky trails, and we ride from 10 to 30 miles a week most weeks. Lots of hills and single track, but always some fire roads as well. In past years, when I used Epics and Easy Boots, they were harder to get on so I had him barefoot most of the year, and he did super. This year **I** got addicted to the EasyCare Gloves because they are so easy to use - and he moves awesome in them - however his feet didn't condition as nicely as they did in past years. I'm trying to wean us both off the Gloves a bit, to use them only when he needs them.

So I've started riding him barefoot more, and he hasn't had boots on for the 50 miles ridden before these pictures were taken. We ride on a lot of cobble stone at one park, lava rock at another, and soft trails with lots of rocky stretches at another. Rock is everywhere up here!

The frogs in these pictures shed last month so are immature but have great shape. His sole is thinner than I like because he shed his thick summer sole callous last month and is on a damp pasture so his sole is wearing more temporarily, but as I watch his feet, the stimulation is encouraging more sole to grow. He does fine barefoot on all but the super rocky roads in this area.

These healthy frogs will hold up great over the winter, no matter how much wading and mud Gabby gets into!!


I'm not saying these are the worlds best feet by any means... they aren't. And this better not be the worlds best trim because its a fast, but carefully done. trim... not a "special for the camera" trim. Its what I do now on feet like these. I love the fact that Gabby is very comfortable in his bare feet on most trails.

These feet really work for Gabby. Because the fronts were booted (I love the easy Gloves!) most of the season, and he's shed his sole callous, so his sole is thinner, but these feet are super comfortable for him to live in, and, booted or bare, he IS super sound.

The healthy, if immature, frog is part of the reason. On a scale of 1 to 10 with 10 being great, this frog and sole is about a 7 or 8. Walls are an 8.




Clifford is a young QH who came out of shoes June 2009. He had a lot of imbalance from poor shoeing, but no real problems. His heels were a bit contracted from the shoes, but have opened up nicely.

His owner John rides him quite a bit, and he is 30 says into a 90 day Reining training program, full-time training.

John was VERY skeptical about taking his main riding horse barefoot; none of the western folks he knows have barefoot horses, and he was open about his concerns about sending Clifford into training barefoot.

Clifford has done awesome, though, the trainer is very happy with his movement, and he never needs boots for his arena work or for walking on the graveled roads at the ranch. John does boot him for trail riding, and probably will until next summer.

Clifford and Magnum (below) live together on a 1 acre pasture that holds 4 horses. The soil is slightly sandy and slightly sloped, and they are fed a grass hay forage.



Magnum belongs to Clifford's owner, and is a retired gelding who had been barefoot for a year but had super long toes, wall distortion and a very rough trim when I first worked on him.

I added his pictures because they were an interesting contrast to Clifford's. When Johns 3 horses went into this pasture in the early spring, it had been empty and had lush, tall grass. Magnum (and Cassidy, the 3rd horse), shows some wall separation in these pictures as the last of this wall grows out. The fact that he shows wall separation may be related to the long walls and toe, but Clifford was getting a lot of riding and that may be why he didn't have wall separation.

Magnum had ring bone for a few years, and since starting this trim in May of this year, he has gotten sounder but is still an older retired horse. Not uncomfortable, he has some arthritis but probably could be ridden lightly. He is comfortably pasture sound.

Magnum's whole body has changed since I started trimming him... just being barefoot isn't enough! A bad trim has the same deleterious affects on a horses health and movement as a poor shoeing job. His toes were at least an inch too long, his heels were high and contracted, so his stance was base-narrow and his shoulders were sore.

Not all barefoot trims are the same, not all trimmers have the same skills and knowledge. Our differences are great as long as the horses are sound or moving comfortably, but that isn't always the case.

Its always okay to ask questions and want to learn more about your horses feet.


Martha (15 years) & Dixie (5 years)

These pictures are interesting for several reasons.

I started trimming these mares in the early spring of 2009, when they both had very long toes and mild laminitis from the pasture they lived on, and I believe they were fed alfalfa, oat hay and higher carb supplements. Their owners, a very conscientious young couple, got serious about diet as soon as we talked, and changed them over to a low carb forage & pellet, but weren't in a position to do anything about the stressed pasture they lived on immediately, hence the wall separation and stretched white line that is still growing out.

This season they have paddocks set up to keep the horses off the grass when its rich.

They ride a fair amount, at local parks, often at the beach and recently at Yosemite. Dixie is in Renegade boots because her feet too round for the Gloves, Martha is in Gloves. The owners "use boots as needed" on the front feet, like most of my trail riding clients. (endurance rider who like to trot and canter a lot typically carry or use rear boots).

What's most interesting about these feet is they are about 90% of the way through growing out the bad wall, and still have a tiny bit of separation in the frogs too... not bad enough to treat, but enough "frog separation" that I needed to trim some flaps each time I'm there. This stuff is generally diet related..




Timothy is a 30 year old TB who owns and is owned by Diana Thompson, a great client who is an acupressure specialist and teaches body working.

Diana also has a comprehensive book on Acupressure for Equines, which I own and use regularly. Check it out!

Many of my clients used Diana for their horses body work, saddle fitting or had been to her acupressure clinics. Because their horses are moving so well barefoot, they mentioned me to her, but Diana was VERY skeptical about barefoot before we talked because she would see so many barefoot horses who had been invasively or incorrectly trimmed as a body worker... she had seen a lot of barefoot fanaticism but many of those fanatics had sore footed horses.

What she had gotten used to was horses whose feet would all be so sore that it was hard to diagnose a specific lameness, but as a body worker, Diana could see it in their stiff, sore bodies. Not all barefoot is the same. Invasive or inappropriate trimming can make a horse sore. Forms of this are over thinning the walls, leaving heels or toes too long, thinning the sole or removing supportive bar. Or NOT treating thrush and frog infections! Bad hoofcare often results in sore bodies.

Timothy has been shod his whole life, and Diana had tried taking his shoes off once before, but Timothy had horrible problems with the transition and Diana almost lost him.


At the end of April, 2009, after seeing work I had done on many common clients, she invited me out for a Timothy Consultation. Diana and Timothy are VERY close, and after the consultation, when she asked me to pull his front shoes, I felt... honored. And thus began the 5 month transition period!

Timothy is still a super athletic horse even though at this point he is 30, but he is also fragile in his own way, and the footing at Diana's barn, a very abrasive sharp gravel, meant a lot of booting early on. But it worked! Timothy is barefoot almost all the time now, and is very comfortable.




Gulala is an older TB rescue, very retired, who has a well balanced low carb diet and lives in a large paddock with several other mares. This paddock is in an area that doesn't drain well, its essentially a flood plain near a creek, and the pen gets extremely muddy in the winter. It is picked out on a regular basis, and most of these horses feet are picked out and checked daily.

The boarding stable manager is working towards improving the footing in all the paddocks, but in the winter, these paddocks get very swampy . They lay deep wood chips to keep the horses feet from being down in the mud all the time, and it works well.

This environment is one of the hardest to fight thrush in, and when these horses do get thrush - particularly if there is something else going on line an immune system problem or Cushing's - cleaning it up is tough.

This frog is proof it can be done. This owner has done a super job at getting this frog healthy!


Viggo is a mature OTTB who lives in the same environment Gulala lives in.... I'm adding these pictures because his bars were lose and I just scraped them off It also shows how I trim frogs...


King, Morgan Mule

King is a young Morgan cross mule who gets **lots** of riding. He also lives in a wonderful "Paddock Paradise" with his donkey buddy, and moves nonstop.

He's also one of my favorite clients (I say that about many of "my" horses and mean it!)... he's a super animal in every way. VERY well trained, lots of character. I adore him.

Most of his riding is on trails. His owner packs with him, trail rides 4 to 6 days a week, many long distance rides, barefoot on all terrain (lava rock to shale to cobble stone) and he does awesome. I gave her a pair of EasyCare Edges for her birthday in case she needed them for a recent camping trip to a place that has particularly treacherous rock, and she didn't need them.

He also gets shown and does very well. He was at Bishop Mule Days and the Sonoma Equine Extravaganza this year. He has a bit of driving training and goes english or western.

King has a slight twist to his right rear leg and has a "curl" on his frog. He gets regular chiropractic and bodywork, has saddles that fit, etc. He's extremely sound.

He has a tight sulcus and if we didn't keep it trimmed it would get thrushy.


Honey, Belgian PMU Rescue

Honey belongs to my friend Michelle at Harvest Moon Ranch , and a neat lady named Lisa Bishop does her trimming.

Lisa is a very talented trimmer but is also a VERY talented natural style trainer, and she started trimming Honey because Honey was cleaning up the paddock with my Chaps! She's HUGE!

Lisa, OTOH, weighs a third of what I weigh... you would think I'd be a better match? No. Definitely not. Honey is a sweet docile oversized pony for Lisa. She was a tyrant with me!

I did trim her up until this spring, and these frogs have changed remarkably since I was doing them. We used to fight deep sulcus infections on here constantly, and now? These frogs are perfect.

What triggered the change? Michelle started her on mineral balancing.

This mare spends the winter in a very wet "dry lot" that is partially covered in wood chips.

These feet look awesome Lisa.... I'm glad you're trimming them & not me!


UB, Dressage Pony

UB is a pony who supposedly did 2nd or 3rd level dressage at sometime in her past, and ended up at Harvest Moon Ranch following a dramatic colic surgery that resulted in the loss of a huge piece of bowel. She struggled for months to stay alive, and Michelle deserves a great deal of credit for her making it. Like the other horses here, she lives in a paddock with chipped wood footing. Her feet are fantastic!
