The idea of losing a horse can feel daunting for any owner. But having a plan in place, especially for carcass disposal, can make an emotional situation slightly less overwhelming. “In my experience—I’m also a horse owner—horses tend to pass away at the least convenient times,” says Krishona Martinson, PhD, professor and equine extension specialist at the University of Minnesota, in Minneapolis. “That could be when people are on vacation, in the winter when the ground is frozen, or just during an already hectic time.”
Although the idea of losing your horse can be difficult to consider, thinking ahead about body disposal can help you feel more prepared.
Know What’s Legal for Horse Burial in Your Area
State and local regulations dictate the options available to you. Your plan should include verifying what’s allowed in your area, says Robert Coleman, PhD, PAS, associate professor and equine extension specialist at the University of Kentucky, in Lexington.
The four legal methods most commonly available are burial, composting, cremation, and rendering.
1. Burial is often the default choice for horse owners who have enough land and live in a municipality that allows it. When soil conditions and water tables allow, Martinson says she considers on-site burial a viable option.
Digging a hole large enough for a horse (more than 6 feet deep and 7 feet wide) requires heavy equipment. Renting machinery or hiring someone with that equipment can make the task manageable.
Proper burial must prevent scavengers from accessing the carcass. Pentobarbital, the euthanasia drug commonly used in horses, remains in the body after death and can be lethal to scavengers, says Coleman
2. Composting is a less conventional but increasingly accepted method, says Martinson. Researchers at the University of Minnesota Extension are actively researching cattle composting, with findings applicable to horses. “Composting is something I believe anyone can do with the resources we have freely available on our website,” she says.
3. Cremation is a popular choice for owners of small animals, but large animal composting can present more complications due to cost and logistics.
“It can be quite expensive—upwards of a couple thousand dollars,” Martinson says. “And you usually have to transport the horse, which isn’t always practical.”
4. Rendering was once widely used but now more difficult to access. The process involves converting an animal carcass into useful materials such as fats and proteins. Many rendering services have restrictions based on how the horse died. Some require proof of natural death or euthanasia by gunshot rather than chemical methods.
“(Renderers) might not accept the carcass depending on the use of the rendered products,” Coleman says.
Martinson and Coleman encourage horse owners to reach out to state extension services or university experts to learn about the options available locally and select the best fit for their situation. The United Horse Coalition recently released Saying Goodbye to Your Equine, which includes additional resources to help owners plan for end-of-life care. “Whether you’ve lived on your property for 40 years or just four months, you need to know your options,” Martinson says.
