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

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.**

And as always, contact your veterinarian for more information as they remain the best source of advice!

"F" IS FOR FALL-CHECKLIST! 🍂🍁

As the cooler weather moves in, now is the time to crack down on housing, nutrition, and preventative health strategies suitable for the arrival of winter.

Check out this list of essential items on the horse owner's fall to-do list, but there is much more that needs to be done—like having your horse's blankets repaired and waterproofed, securing and storing hay properly, assessing your shelters for safety and soundness, etc.

Note that your equine veterinarian is one of your greatest allies this season, so be sure to consult them and discuss vaccination and deworming protocols appropriate for your horse’s situation. This is also a great opportunity to chat about recommended changes in nutrition and exercise programs as well!

The summer heat and sun won't be letting up any time soon, so make sure your equine friends are adequately protected from harmful UV rays. ☀️

Hot summer weather puts horses at risk not only for dehydration and heat stress but also the skin damage and discomfort that accompany a sunburn— just like humans.

A lot of equestrians love some chrome on a horse, but it's important to remember that those beautiful white markings and the non-pigmented pink skin underneath are more likely to suffer from sunburn, especially in areas where the skin is more sensitive — like around the eyes and the nostrils.

In addition to the pain and discomfort, horses that are prone to recurrent sunburn may also face other long-term consequences, like the increased likelihood of developing squamous cell carcinoma (a common cancer).

If your horse is susceptible to sunburn, contact your veterinarian for more information about sun damage and recommendations to keep your horse protected this summer.

"Cool" hot weather tips! ☀️

The notion that a hot, recently exercised horse needs to walk until they are completely cooled off is a myth. A 2020 study found that out of the five methods tested, the quickest way to return to normal body temperature was stationary with continuous tap water application. This doesn't mean that you should abruptly stop exercise—finish your ride or training session with a slow walk to allow your horse's heart rate and breathing to gradually return to normal, but after that your sweaty, hardworking horse should be offered a cool shower and drinking water (small but frequent amounts) without delay.

Overall, enjoy your summer rides but be aware of signs of heat stress in your horse. When heat and humidity soar, even moderate exercise can push your equine friend's body temperature beyond safe limits! Be sure to contact your veterinarian for more information about heat stroke and for recommendations tailored to your horse's individual situation.
