The Horse's Advocate Podcast

My mailbox and inbox get a never-ending stream of advertisements, all promising that my horse will become free of disease or super-athletic. Some boast scientific research backing their claims, while others have endorsements from winning contestants. All use the time-tested formula of identifying a condition your horse might have, then claiming their product will resolve it. But is any of it true?...

Foals are especially vulnerable in their first months of life. Think about the first time you met a newborn foal—did you know it takes both knowledge and experience to protect them well? In this podcast, we'll dive into three of the top challenges horse owners face with foals just after birth to a few months old. This isn't a complete list, so remember, teaming up with a seasoned professional will...

Filing off sharp edges inside a horse's mouth may seem a bit odd at first glance. If nature is perfect, you might wonder, why would horse teeth need this help? How did horses get by without floating, the process that smooths those sharp edges? These are thoughtful questions, and I explore them—and more—in this podcast. Some of the ideas I present are: - It is the threshold of pain, not how sharp t...

Glucose is an essential sugar for horses, but too much of it can be harmful. While diet is your main tool for reducing glucose intake, what can you do when your horse still struggles with glucose and insulin control? And are there medications that can help lower blood glucose? Let's explore one option together. If dietary changes are not enough, other strategies can help manage high glucose and in...

Glucose is one of many sugars. It is an essential nutrient for both horses and people. When talking about sugar in food, you might hear words like carbs, starch, fructose, lactose, saccharide, or others. But for now, let's just focus on glucose. Without it, our horses—and we—cannot survive. Yet glucose damages everything it touches inside the body! It is so harmful that the phrase "glucose disposa...

New horse owners join the community every day, from children to adults with little or no experience. Many expect horse ownership to be as simple as using everyday conveniences like microwaves or making phone calls. Yet, horses are fundamentally different. Unlike technology, which responds reliably to our commands, horses have evolved to interpret and respond to their environment using all their se...

Horses graze on grass and plants, not trees, because their digestive tracts—shared by equids, tapirs, and rhinoceroses—cannot digest wood. Unlike ruminants (cattle, deer, goats), they avoid lignin. When starving, however, horses may eat almost anything, which is why some plants and trees become toxic. The goal of this podcast is not to make you plant and tree experts, but to help you appreciate tw...

Science relies on asking questions, testing them, obtaining answers, and questioning those answers again. Scientists never settle; their curiosity drives them to consider all possibilities, regardless of prior beliefs. There is never a final answer—only answers that are close. This approach depends on continuous inquiry and skepticism. Horse owners are not scientists, and they are not trained to p...

NOTE: There is a section about 1 minute long where it sounds different because I inserted a video of me driving my hands-free car. To see it, please watch this on YouTube.   We all know that horses are not robots. Robots are mechanisms that do not think; they simply execute programmed instructions. They are designed to perform tasks that humans are unable or unwilling to do themselves. Examples in...

The first time I heard the words "Sugar Fungus" used with horses, I thought it might be a new, and possibly harmful, reportable disease. I braced myself for the thought that another new disease was invading the world of horses, and that there may not be a cure. However, to my surprise, I learned that sugar fungus is the translation of a common yeast called Saccharomyces: Sacro meaning sugar, and m...

The April 2026 edition of the Journal of the American Veterinary Medical Association (JAVMA Vol. 264, #4) caught my attention with 4 articles and an author's response to an article. In this podcast, I use the information gathered from them to suggest that many new veterinary graduates are a combination of the following: They may be focusing more on acceptance from their peers over competent patien...

Equine Metabolic Syndrome (EMS) and Insulin Resistance (IR) are just words to most horse owners. We hear them, and we hope our horse doesn't "get them" attached to their health report. Even the veterinarians get a bit confused about how horses get started on the path of poor metabolic health. Expressions are created that lack meaning, such as "sugar is evil." If it were, why does it exist? So, I d...

Cancer is defined as normal cells of the body behaving badly, at least that's the simple explanation given by AI. It's more complex than that. Luckily, in horses, cancer is rare; three of the top five occur in the skin, where we can see them. Of the other two, one is in the ovaries and remains locally there, and the other is in the blood, which isn't good. This podcast covers two related topics: t...

My wife placed a supplement ad for horses in front of me and said it was "interesting." She knows me, so she was testing me to see if this one was really special or just another waste of money. Rather than give the same old response about marketing ploys to take money without substantiating the product, I decided to go deeper. The expression "correlation does not mean causation" is familiar. But w...

Cornell Veterinary School is well established as one of the best veterinary schools in the world, renowned for specialties like wildlife, infectious diseases, and equine practice. A quick search of data shows that Cornell's vet school was ranked #1 from 2000 (no data before this) until 2015. Currently, it is ranked #2 in America (behind the University of California, Davis) and #3 in the world (beh...

Most advice from horse professionals focuses on solving problems using standard approaches, rather than looking for the root cause. For example, if you look at a chart of all causes of death in horses, dental issues barely register compared to colic, laminitis, or metabolic diseases. Many horse owners truly love their horses, even if they struggle to explain why. They want the best for their anima...

Horses have tiny engines within almost every cell of their bodies, and each of these runs on fuel that comes from the food they eat. These engines are called mitochondria. This podcast describes these engines and what happens to our horses when they stop working efficiently. One thing is for certain: adding more fuel doesn't help them run better. The only way to improve the health of horses is to...

Having fear can cripple most people from enjoying life. Horse people suffer more than most from fear of horses because what they enjoy most in life are horses. This becomes a paradox that worsens their entire life. However, there are tangents to the fear horse owners have, such as the fear that they are not caring enough for their horses, and, therefore, the horse will suffer from the owner missin...

The temporomandibular (TM) joints in horses are evolutionary masterpieces that have evolved over 55 million years. But suddenly, the experts are saying that the joints are failing because the mouth has become "unbalanced." I disagree.  The experts say that unridable horses have pain in the TM joints that connect the jaw to the skull. Their conclusion is that the teeth are "unbalanced," with an une...

First Principles Thinking involves examining complex problems in terms of their most fundamental and undeniable truths. Applying First Principles Thinking to everything we do with our horses to help them, and us, in every task, is what I have been doing for a while at The Horse's Advocate. Over 2,000 years ago, the Greek philosopher Aristotle said that "the first basis from which things are known"...

The Ketogenic diet is popular for weight loss in humans, but does it work, and can it work with my grass-eating horses? The simple answer is yes, and you don't need to make them carnivores! A ketone, also known as beta-hydroxybutyrate, can be produced in two ways in horses. The first is the bacterial breakdown of cellulose in their hindgut. I have discussed this elsewhere, and it is the primary so...

Indoctrinate is a verb defined by Apple's Dictionary as "teach (a person or group) to accept a set of beliefs uncritically." Apple's thesaurus offers these similar words: "BRAINWASH, propagandize, proselytize, inculcate, re-educate, persuade, convince, condition, discipline, mold; instruct, teach, school, drill, ground." It implies that the students, or the horse owners, believe everything they ar...

Every day, all body proteins break down into the small building blocks of amino acids, sending these free molecules into a recycling program for use in building other proteins. Why this happens remains a mystery, as does the reason we don't lose our muscle shape or our memories during the process. Over time, our horses show loss of protein as weakened hoof walls, crushed heels, poor hair coat, los...

The debate over horse dentistry needs to be resolved before it escalates into an all-out war, leaving horses without the dental care they need. The two main issues fueling this conflict—hand floating versus power equipment, and the debate over whether only veterinarians or non-veterinarians should perform dental work—have been ongoing since the 1960s. I know this history well, as I began my own jo...
