Hoof-care and Farriery
Owners play a vital role in the hoof health of working equids. They should work with a suitably skilled and knowledgeable farrier to ensure proper care of their animals’ hooves.
THE IMPORTANCE OF APPROPRIATE HOOF CARE AND FARRIERY
The saying ‘no hoof, no horse’ is well known, because it is true not only for horses but for donkeys and their hybrids too. Working equids bear their whole body weight, plus the weight of any load, across their four hooves. Hoof problems cause pain, lameness and suffering.
The hooves of horses, donkeys and mules are always growing. If there is an imbalance in the rate of growth and wearing away (e.g. becoming too long or short) this can cause pain and lameness.
Shoes can be applied to protect equids’ hooves from wearing away too fast. The placement of shoes is a unique skill and only properly trained and experienced farriers should perform this task.
Poor farriery, including imbalanced or overzealous trimming, the application of poor quality or unsuitable shoes, or the incorrect placement of shoes or nails, is a significant welfare concern for working equids. These can cause pain, lameness and suffering with every step that working equids take.
Access to quality farriery for working equids is limited as there are limited opportunities for people to receive appropriate farriery training in Low- and Middle-Income Countries.
WHAT AFFECTS HOOF HEALTH?
See appendix “Assessing hoof health and farriery” for more information on how to properly evaluate hoof health.
Provision of daily hoof care
- Twice daily picking out of the feet can help to prevent foot infections and sole bruising from stones, sticks and other materials.
- Regular hoof inspection also gives owners the opportunity to identify any changes which might require intervention from a suitably skilled farrier.
Nutrition:
- Poor nutrition can lead to poor hoof horn quality making cracks more likely.
- Over nutrition with rich, high sugar feeds can lead to a disease called laminitis where the laminae, the structures connecting the hoof wall and the pedal bone, become inflamed, weaken and stretch causing severe pain and suffering to the animal.
Climate and weather:
- Wet environments can make hoof infections more likely, and cause the hoof horn to become weaker and reduced in quality.
- Soft, wet ground can mean that hooves become overgrown as they are worn away more slowly. Suitable trimming may be required more frequently in these environments.
- Hot and dry environments can make hoof horn more brittle and prone to cracking.
Location/environment
- Working on man-made roads in urban areas leads to increased hoof wear and a greater need for shoes.
- In agricultural areas equids may work on softer surfaces, increasing the need for frequent hoof trimming.
- In areas that are very stony and/or uneven, cracking of the hoof can be more common; shoes may help prevent bruising of the sole.
Conformation of the equid
- Limb conformation is closely linked to hoof shape and balance, and should always be considered when examining the hoof.
- There is a high prevalence of limb conformational abnormalities in working equids [1,2] which can lead to distorted hooves that may contribute to pain and lameness.
- Skilled farriery is required to help manage the impact of conformational abnormalities on the hooves of working equids.
Availability of skilled, well-equipped farriery services
- Owners often lack the skills to provide farriery care to their animals
- Suitably trained and equipped farriers provide the most appropriate farriery service for the animals under their care.
- There are limited opportunities for farriers to receive quality training and this, especially when combined with poor resources (equipment), can lead to inappropriate and ineffective farriery care being provided.
- Animals should always be treated and handled in a quiet, compassionate, and safe manner during any trimming or shoeing.
HOW CAN WE ENSURE GOOD, SKILLED FARRIERY IS AVAILABLE TO WORKING EQUIDS?
- Identify who provides farriery services within your region
- Identify any gaps in their provision of skilled, safe farriery
- Identify any gaps within the wider farriery provision system including: opportunities for farriery training, availability of tools, quality shoes and horseshoe nails
- Identify potential opportunities for strengthening farriery provision by working with different stakeholders for example: veterinarians, veterinary training institutions, local professional or leisure horse service providers, makers/suppliers of farriery tools and equipment.

Appendix:
ASSESSING HOOF HEALTH AND FARRIERY
Observe the animal standing and walking to assess for pain and lameness. Then view each limb and hoof of the animal from the front, side and back to assess hoof shape, hoof pastern axis and horn quality. Lifting each foot will enable the evaluation of shoe quality and placement, observe for foreign bodies and assess the quality of the sole of the foot.
Hoof shape
- The hoof should be generally symmetrical and even in shape.
- The front wall of the hoof and the heel should run at roughly parallel angles and in straight lines, with no concavity (dip) in the wall.
- The toe should not be abruptly cut so that it is almost at right angles to the ground (dumping).
- Asking yourself the following questions might help you appraise hoof shape
- When viewed from the side, is the toe too long or too short? Is the heel too long or too short?
- When viewed from the front, are the hoof walls straight?
Hoof pastern axis:
Hoof pastern axis is the alignment of the hoof, pastern and fetlock when viewed from the side. This, from the fetlock joint down to the tip of the hoof, should be a straight line in horses. In donkeys, the hoof may be more upright leading to a slightly broken-forward appearance compared to the horse. (WEVM)
Hoof horn quality:
The hoof is made of a keratinised material called horn. The quality of the horn can indicate hoof health.
- A healthy hoof should be intact without cracks or only minor, short cracks at the ground surface.
- Poor horn quality is indicated by cracks that extend up more than half the height of the hoof wall and/or cracks that originate from the top of the hoof.
- Crumbling and flaky horn can indicate poor horn quality.
Shoes:
- If shoes are used they should be made of suitable material for example metal or rubber. Shoes made from repurposed car tyres are not suitable and are likely to result in nails being driven into the sensitive part of the sole
- Shoes should be smooth around the outer edge, well fitted to the outer perimeter of the hoof, cover the heels appropriately and follow the natural shape of the hoof.
- Metal shoes with rough edges, bulges or ridges are of poor quality and unfit-for-purpose.
- Horseshoe nails should not enter the sensitive parts of the hoof.
- Horseshoe nails should always exit the hoof with enough material to form a smooth clench.
- Carpentry nails are not fit-for-purpose and inappropriate for safety reasons.

In horses the front hoof should be rounded while the hind feet are more pointed

Donkeys’ hooves tend to be more upright and oval in shape than horses’ hooves.
Their hoof-pastern-axis may be slightly broken forward. Donkeys have a slightly different hoof structure to horses and often bear more weight on the sole of the hoof. Donkey hoof horn has a higher moisture content and is less prone to cracking; thus it is more prone to severe overgrowth curling forward off the ground. |

Mule hooves have similarities to those of both horses and donkeys
