Horses with Cushing’s either don’t have enough dopamine present in their body or the body is not able to properly recognize it. This can directly affect the adrenal glands and the kidneys, making the horse more susceptible to infections. Research has also shown that Cushing’s disease can also cause neurologic disease. In almost every case of equine Cushing’s disease laminitis becomes present which will cause pain and sensitivity in the hoofs, from the deterioration of the lamini.

Euthanasia, or having a horse put down, is something that almost every horse owner, grooms, caretakers, barn managers, and trainers must face making this tough decision at some point. Veterinarians choose to euthanize a horse through lethal injection to make sure that your horse is not aware of any discomfort or pain as life leaves its body. Making sure the process is simple and quick is one of the veterinarian’s top priorities. At no time does a vet wish this to be a long or drawn-out process or allow the horse to feel any anxiety or discomfort associated with this process. 

What happens to horses after they are euthanized?

Disposal of the deceased horse can be expensive as well as logistically challenging. Options for equine carcass disposal are cremation/incineration, burial, landfill burial, rendering, bio digestion, and composting. Not all of these options are available in every area, so it is very important to do some research and find out what your options are and what the cost will be.

If you want to bury your horse on your property you must first check the laws in your area to see if it is something they allow. There are usually specific requirements such as placement, depth, and size of the hole and how it should be handled.

The main concern with property burial is the possibility of the groundwater becoming contaminated and the odor. If you are able to bury your horse on your property there are many things that must be considered when choosing the site. For the site to meet the specific jurisdictions, the burial site must be 100 yards or further away from wells, streams, and other water sources.

In some states, it is illegal to bury a horse that was chemically euthanized because of the possibility of increased contaminants from the injection. The ideal trench or hole where your horse will be placed should be approximately 7 – 8 feet wide, 9 – 10ft deep, and at minimum 3 – 4 feet of dirt that will cover the animal’s remains. For this task, many find using a backhoe is ideal. Although it can be dug by hand, it will take some time to accomplish. Some states require a permit to legally bury a horse on any property so always check what your county’s laws are before you begin.
