It’s not uncommon to find horses and ponies living well into their 20s and 30s, thanks to continuous advances in nutrition and health care.

Horse owners have a big impact as well and can help their horses thrive in their golden years through proper management practices like those illustrated in the graphic. But remember, although there is much you can do on your own to keep your older horse happy and spry, some conditions associated with aging require medical intervention.

Scheduling regular visits and keeping a good line of communication with your veterinarian will allow you to respond quickly to any ailments or injuries that could cause your horse a serious or prolonged set back. That means less worry for you, and a better quality of life for your old friend!

DO YOU KNOW HOW TO SPOT COLIC IN HORSES?

Colic indicates a painful problem in the horse's abdomen (belly), which can be caused by a number of different conditions. Less than 10% of all colic cases are severe enough to require surgery or cause the death of the horse; nevertheless, every case of colic should be taken seriously because it can be difficult to tell the mild ones from the potentially serious ones in the early stages.

Horses show signs of abdominal pain in a wide variety of ways, and usually a horse shows only a few of the signs during an episode of colic. The rule of thumb is — the more obvious the signs of pain, the more serious the problem.

If you suspect the horse is suffering from colic, we suggest that you:

• Alert your veterinarian immediately

• Remove all hay and grain from the horse's surroundings

• Don't medicate without your veterinarian's approval, as pain medications can mask clinical signs

• Walk the horse around if it's continually rolling or in danger of hurting itself — but do not tire the horse with relentless walking and don't approach the animal if it's not safe

• Keep the horse under close observation until the signs of colic resolve or the veterinarian arrives

The key to increasing the chances of a good outcome is to identify the problem early and get your veterinarian involved from the start.

Please note that this is not an exhaustive list of colic signs. Horses are individuals and may display signs of pain in a variety of ways. Always consult your horse doctor for more information.

As blanket season is in full force upon us, here is a very important reminder courtesy of the horse doctors at Miamitown Equine Veterinary Services:

"When securing blankets, make sure that the snaps/clips are facing inward, toward the horse! If they are facing out, they can easily become stuck on something, like the hay net in the picture."

FUN FACT FRIDAY!

Are you familiar with the many adaptations that help your horse stay warm during the cold winter months?

🌾 Hindgut digestion of hay produces the most heat, acting as a small furnace inside of the horse. This is why free choice; good quality hay is so important in the winter.

💪 Horses have a huge muscle mass and muscle activity produces heat. This includes running and playing and even shivering if their body temperature starts to drop. It is important to remember that these activities also will result in a bigger caloric demand so free choice hay and in some cases, grain, is often needed.

🧥 To blanket or not to blanket is a constant debate but either way, as it starts to get cold your horse will grow a thicker coat. If you decide to leave your horse unblanketed you may notice that they look “fluffy”. This is due to a phenomenon called piloerection where the hair stands up to better trap air within. Two layers of the coat also help with warmth. The inner layer is softer and has air pockets to create an insulating layer. The outer layer is coarse and has oils that keep moisture from penetrating the insulating layer and keep the horse warm.

⚖️ Wild horses go into the winter heavier than ideal, and the fat serves as an extra layer of insulation. However, if a horse is going to be kept heavily blanketed and in a barn during the cold weather months this is unnecessary and can lead to obesity related issues.

🦵Their distal limbs (below the knees and hocks) are made of mostly bones and tendons, tissues that are resistant to the cold temperatures.

🦶The hooves have an alternative route of blood circulation through larger vessels that can be used in low temperatures. This is why horses can stand in snow without detrimental effects.

👃A horse’s nose has a robust blood supply and is rounded so that it is less susceptible to frostbite than a human’s nose.

Though most people usually think of donkeys as very hardy, sturdy animals, this doesn't mean that their feet don't require the same careful attention that we give to their other equine cousins.

Donkeys should have their feet picked out daily and see a farrier to be trimmed every 6-10 weeks. Failure to trim donkeys' feet on a regular schedule can result in serious pain and health issues in their hooves.

Signs of foot pain in donkeys can manifest as very stoic weight shifting, especially on hard surfaces, and increased periods of laying down.

Additionally, it is important for farriers to take into account some of the differences between donkeys and horses when trimming their feet.

• The foot should be more upright
• The shape should more cylindrical rather than conical shaped
• When looking at the bottom of the foot, it should be U-shaped rather than an oval
• The sole doesn’t flake off and will need to be trimmed to create a concave sole
• Thier feet appear to grow more from the heel than from the other parts of the foot
• The point of the front does not go as far forward

Thank you to the Horse Owner Education Committee for providing this information.

WHAT CAUSES HOOF ABSCESSES?

Sooner or later, nearly all horse owners will deal with a hoof abscess. But what does "hoof abscess" actually mean?

Although most commonly seen during the wet winter and spring months, hoof abscesses can plague horses year-round and usually occur when debris and bacteria enter the foot through hoof cracks and wounds, even horseshoeing holes. The bacteria then get trapped between the sensitive laminae (the tissue layer that bonds the hoof capsule to the coffin bone) and the hoof wall or sole and create pus; the pus builds up over time and puts pressure behind the hoof wall or sole, until it causes the sudden onset of acute lameness when the pain finally becomes too great. (The diagram shows a simplified view of the equine hoof to help visualize the structures involved in this process.)

Hoof abscesses can mimic other more serious diseases or injuries, so involving your veterinarian early on in the diagnosis and prompt treatment of this condition is always a good idea. Some abscesses will be uncomplicated and rupture on their own like a large pimple at the coronary band or heel bulbs; other abscesses, however, could require radiographs and will need to be surgically drained.

Strangles is one of the most commonly contagious diseases of the horse (worldwide) and in 2017 it became a nationally monitored disease. This condition is caused by bacterial infection of "Streptococcus equi subspecies equi" (referred to as "S. equi”), which typically infects the upper airway and lymph nodes of the head and neck and is highly contagious in horse populations—particularly affecting young horses.

Transmission from horse to horse usually involves direct face-to-face contact, or exposure to contaminated feed, water, hands, veterinary instruments or grooming tools. A stall or van recently used to house or transport a horse that is shedding the organism may also be a source of infection.

WATCH OUT FOR ASYMPTOMATIC CARRIERS!
It is not uncommon for strangles infections to recur on a farm with previous outbreaks of the disease. The primary source of recurrent infections are most likely asymptomatic carrier horses—animals who display no clinical signs but may continue to shed the bacteria for months to even years, serving as a continual source of new infections.

If you suspect a strangles outbreak, be sure to involve your veterinarian right away to determine the diagnosis and the best control practices for your particular farm. Without control and biosecurity measures, a strangles outbreak will ultimately affect all susceptible horses, last longer, and have a greater chance of leading to complications.

**Please note that strangles is a reportable disease in some states.**
