Basic Life Skills for Horses

As a horse owner, have you taken responsibility for your horse’s ability to handle potentially stressful situations? Are you prepared for the inevitable emergency situation? Taking the time to evaluate you and your horse’s ability to handle these situations BEFORE they happen will help ensure better outcomes. Here is a list of basic life skills important for all horses, regardless of age or location!

  1. Basic handling, including catching, haltering , and leading your horse. You should be able to touch your horse’s body and legs and pick up all 4 feet. If you cannot catch your horse, how can your veterinarian examine him? If you never catch your horse, waiting until he is sick or wounded will not make the situation easier. If you cannot touch your horse’s legs or pick his feet, it is unfair to expect he will allow the farrier to do so safely. Remember that consistent handling is key to success and progress!
  2. Temperature- If you own a horse, you need to own a thermometer, know how to use it, and be able to safely take your horse’s temperature.
  3. Oral medications- There is no reason why your horse cannot learn to have his mouth touched and have oral medications administered (including dewormer!) It is highly likely that at some point, you will need to give your horse an oral medication. Your horse may not sip it eagerly from a syringe, but he needs to allow you (and your veterinarian) to administer an oral medication safely- without rearing, striking, running backwards, etc. If this is a weak skill for your horse, check out some of the resource links below for how to help your horse.
  4. Trailer loading- Even if your horse is retired at home, in the event of a fire or other life-threatening emergency, your horse will need to load on a trailer. This is a skill that comes with practice! Waiting until a stressful event forces this scenario is a good way to ensure that your horse does not load safely or in a reasonable amount of time. If you do not own a trailer, it is your responsibility to plan ahead- does a friend or neighbor have a trailer to help you? If your horse does not load reliably, consult with a reputable trainer to help him learn and practice.
  5. Safe behavior for veterinary exams- Your horse might be nervous about your veterinarian administering vaccinations or medications- that’s ok! Let your veterinarian know in advance and be aware of what works best for your horse in these situations- some treats, a twitch, etc- your veterinarian will appreciate the heads up and your respect for their safety. It is not acceptable for your horse to behave dangerously or violently, and such behavior will eventually mean less than ideal outcomes for your horse following illness or injury. Being a rescue is NOT an excuse for dangerous behavior. Consistent practice and de-sensitization training is a worthy investment for you and your horse!

Here are some great resource videos with training and desensitization tips:

  • The British Equine Veterinary Association has a helpful Youtube channel “Don’t Break Your Vet” with short videos of densensitization training techniques to help horses stay safe and relaxed for injections, clipping, deworming, exams, and other veterinary procedures.

Wet Weather Hoof Troubles: Thrush and Abscess

While we are always grateful for precipitation here in Colorado, wet and muddy conditions contribute to the development of two common horse hoof conditions: abscesses and thrush.

Abscesses

A hoof abscess commonly presents as an acute onset severe lameness without obvious signs of injury. Abscesses occur when bacteria is trapped within the foot. Wet conditions can soften the foot, allowing easier access of bacteria. A deep bruise, hot nail, or other foreign body can also lead to abscess formation. Horses with poor hoof quality or white line disease can be more susceptible to abscesses.

Exam findings that help your vet localize the lameness to the foot include an increased digital pulse, localized warmth of the foot, and sensitivity to hoof testers. Radiographs may be recommended to rule out other more serious problems or foreign bodies. In some cases, radiographs may show a tell-tale pocket of gas (infection).

Most abscess resolve in about 7-10 days. The key to improved comfort is drainage of the abscess, resulting in relief of pressure. Care during this time includes application of a poultice to allow drainage while also keeping the foot clean. The most common methods used are a medicated poultice pad (Animalintex) or packing the foot with magnapaste. Both methods help draw out infection and are much easier (and more quickly successful) than soaking your horse’s foot in a bucket of warm water and Epsom salt. A drainage tract is needed for healing, but this tract can potentially allow more bacteria back into the foot, so a proper foot wrap over a poultice pad or magnapaste is essential for cleanliness. Elastikon and duct tape are invaluable for a good foot bandage!

Thrush

Thrush is another common hoof condition linked to wet conditions. You may notice a strong odor when picking your horse’s feet, and wet dark material along the sides and center of the frog. The odor is due to infection with anaerobic bacteria (bacteria that thrive in areas with little to no oxygen). Severe infection can cause sensitivity when using the hoof pick or pressing on infected areas, and sometimes lameness.

Poor hoof conformation and infrequent farrier care can contribute to the development of thrush. Treatment options for thrush include topical drying/antibacterial products (Thrushbuster, dilute betadine, copper sulfate, etc) and farrier work to remove exfoliating frog that may trap additional moisture. A dry environment is also critical.

Observing an acute onset severe lameness in your horse warrants at least a conversation with your vet and most likely an exam. Good management, including a clean dry environment, regular farrier care, and checking/picking out your horse’s feet daily can help minimize his risk of developing a hoof abscess or thrush.

What is Cellulitis?

Last night when you fed your horse you didn’t notice any issues as you performed your quick “once over” before rushing back out the barn door. But this morning they have a severely swollen leg, and they are hobbling around.

What happened? 

The list of possibilities isn’t terribly long, but there are serious things on it: fractures, hoof abscesses, laminitis, joint infections, and cellulitis.  Of course, fracture is the one that no one wants to hear and has significant ramifications.  Laminitis and abscesses typically don’t have the significant swelling described in the “case” above.  Joint infections would likely have been associated with trauma or a recent joint injection, and the swelling would likely be associated with a particular joint, not the entire leg.  That leaves this horse with a likely case of cellulitis. 

If you haven’t ever seen a case, they can be impressively swollen, and this can happen relatively quickly (overnight)! See below for an example.

What is cellulitis

Cellulitis is an infection of the deeper layers of the skin and the subcutaneous spaces.  The pressure and inflammation make it extremely uncomfortable for the horse.  They are usually very painful to the touch (maybe not everywhere they are swollen, but some portion of the swelling), and there is a lot of heat. Severe cases can have serum oozing from the skin. The horse may have a mild to moderate fever as well.

What causes cellulitis?

The infection can initiate from an obvious recent wound, bed sore, “scratches”, or other minor scrapes. It could also be a result of a more significant laceration from days before that seemed to be healing in the right direction.  Another common route that these can begin is secondary to a hoof abscess.  The infection begins in the hoof and then in the right set of circumstances, manages to take hold and cause further infection higher up the leg.

How is cellulitis treated?

If you notice the swelling before it is as extreme as the picture above, getting medical attention could prevent it from becoming such an advanced case.  Medical attention usually consists of antibiotics and anti-inflammatories systemically.  On occasion, a “regional limb perfusion (RLP)” may be justified.  An RLP is a way for the veterinarian to get very high concentrations of antibiotics to the area of concern using a tourniquet and antibiotics directly infused into the affected limb.  Hydrotherapy (cold hosing) is also often indicated. 

Managing cases of cellulitis early is paramount to preventing long term ramifications such as lymph damage (lymphangitis), or laminitis.  Lymphangitis is an inflammatory process in the normal lymph drainage of the limb, and can leave the limb permanently swollen.  If there is enough swelling in the leg during the cellulitic process, it could cause enough vascular alterations to damage the laminae of the foot, causing laminitis. 

If you find your horse with a sudden non-weight bearing lameness (or barely weight bearing), we would always tell you that it is justification for a phone call to your veterinarian, and most likely a visit.

Street Nails – Call your vet immediately

No matter how safe their environment may be, horses will always manage to find trouble. Unfortunately, a not-so-uncommon equine emergency is a sharp object that has penetrated through the bottom of the hoof, also known as a street nail. Any penetrating injury to the bottom of your horse’s foot is an emergency, and timely assessment is essential for the best outcome.

The number one rule for the horse owner is NEVER REMOVE THE NAIL before talking with your veterinarian! The exact location of the nail is crucial for determining the best treatment for your horse. ALWAYS call your vet first! Sometimes a photo can help your vet offer the best advice before evaluation.

Nail prior to removal

In general, foreign objects to the back third of the foot present the highest risk because of the position of important structures and the consequences of infection.

Nail Prior to Removal

Your vet will take radiographs of your horse’s foot prior to removal of the nail to determine its exact location. If the nail has been removed or fallen out, special dye can be injected along its tract that will show up on the radiographs, but it is more informative to leave the nail in place if possible! If the nail falls out prior to evaluation, save it and mark the depth of its tract if possible.

Dye injected along nail tract

The next step is beginning treatment, depending on the location of the nail. If the nail is well embedded, temporary numbing of the horse’s foot enables non-painful removal. The nail tract will then be flushed to remove dirt and debris. A bandage, sometimes including a drawing poultice, is applied to ensure the tract remains clean during healing. Sometimes a hoof abscess can develop during healing. Depending on the nail location, a technique called a regional limb perfusion may also be used.

Performed on the sedated horse, a regional limb perfusion involves the placement of a tourniquet on the limb above the hoof, allowing for antibiotic injection into a vein below the tourniquet. The tourniquet is left in place for up to 30 minutes to allow a higher concentration of antibiotic in the limb below the tourniquet.

If the location of the nail is in a critical location, such as through the center of the frog or potentially involving the tendon sheath or navicular bursa, prompt surgical flushing at a referral hospital is the best treatment to minimize the risk of fatal or career-ending infection.

Timely treatment of any penetrating wound to the foot is imperative for the best outcome!
