Horse Vaccinations

Vaccinations are an important part of keeping your horse healthy. Just like humans and dogs, horses need vaccinations to help reduce the incidence of diseases too. The more horses your horse comes into contact with, the more you need to make sure your horse is protected against infectious diseases. The following guidelines are recommended by the American Association of Equine Practitioners, the AAEP. The AAEP is a group of veterinarians who specialize in horse medicine.

Below are the most important vaccines for a pleasure horse to receive as recommended by the AAEP. The first four recommendations are considered basic required vaccines and the last three vaccines are optional.

1. Equine Encephalomyelitis (Eastern and Western) vaccination is recommended once per year in the spring. Encephalomyelitis is a disease carried by mosquitoes and is found in all 48 continental states and most Canadian provinces. It is a virus that affects the nervous system. Clinical signs range from fever to weakness and possibly to sudden death. Certain areas have a higher incidence of this disease than others.

2. Another mandatory vaccine is Tetanus, this is recommended once a year in the spring. Tetanus is a disease caused by bacteria called Clostridium. Normally this disease is seen in penetrating injuries, like stepping on a nail. The clinical signs are muscular stiffness. The horse is unable to move, and death could result if not treated.

3. Equine Rhinopneumonitis is recommended one to two times per year and prior to horse shows. Rhinopneumonitis is caused by a herpes virus. Clinical signs are typically abortions and pneumonia. This virus spreads rapidly between horses so vaccination is a must.

4. Equine Influenza vaccine is recommended once to twice a year or prior to shows as well. This virus can cause severe pneumonia in horses. Like Rhinopneumonitis, this too spreads rapidly between horses. Often, if there is a known outbreak of this disease, horse shows will be cancelled.

These last three vaccines should be considered only if your vet recommends them. Typically the decision to vaccinate for the last two diseases is done if there is this disease present in the region.

5. Streptococcus Equi, also know as Strangles, is often given as an intranasal vaccine. Almost all horse owners are familiar with Strangles. This disease is caused by a bacterium that makes the horses lymph nodes swell up, making it difficult for the horse to breathe, hence the name Strangles.

6. Potomac Horse Fever vaccine is another optional vaccination. This disease primarily happens to horses who liver near water. The bacterium that causes this disease is linked to snails and the clinical signs include colic and laminitis.

7. Recently on the Canadian prairies, particularly in the Province of Saskatchewan, Anthrax has shown up because of the extremely wet conditions in some parts of these provinces. If you happen to have any livestock and you live in this area, consult your veterinarian about vaccinations for this deadly disease.

By following the basic vaccine protocol for pleasure horses from the AAEP, or one recommended by your local veterinarian, you can keep your horse healthy. Be sure to consult with your veterinarian before starting any vaccines. I also recommend that you get your vaccines from your vet and not by buying them over the Internet. Like human drugs and vaccines, horse vaccines purchased over the Internet may be cheaper, but you have no idea what they contain. Just to save a few dollars do you really want to put your horse at risk of premature death from some unknown concoction put together by an Internet hustler? Your veterinarian is a highly trained professional with the knowledge and training to prescribe the right medicine for the situation involved.

Lameness in Your Horse

Lameness in a horse is one of the most common health problems seen in horses. Two of the most common causes of horse lameness are called laminitis (inflammation of the laminae of the foot) and navicular syndrome (inflammation or degeneration of the navicular bone or its surrounding tissue). By learning about these conditions you can catch them earlier and therefore prevent further damage.

When dealing with lameness in a horse, you have to be observant. Often horse lameness is temporary and goes away with just rest. Other times the lameness can be quite severe and further veterinary care is needed.

Lameness is often seen when the horse is trotting. If your horse is lame, you will notice a different gait to the horse. There are several signs to watch out for when dealing with a suspected lame horse.

Signs of lameness include - trotting unevenly, a reluctance to bear weight on a leg, throwing the head when trotting, and a reluctance to move.

If you notice any of these signs you should contact your veterinarian immediately, and don't ride your horse. While you may be able to tell which leg is affecting the horse, the veterinarian can identify the exact location that is causing the problem.

The veterinarian will most likely start the examination with observing the horse trotting. After that he (or she) will usually start at the foot of the lame leg and work his way up the leg to pinpoint the location of the pain.

When looking at the feet, they look for many possible causes of lameness. It could be as simple as an incorrect shoe, or more complicated such as navicular syndrome or laminitis.

They will feel the hoof for any signs of heat, pain or swelling. Also, uneven wear on the hoof is another sign that there is a problem.

As they work their way up the leg, they feel for any areas of heat or swelling. They also palpate the tendon and joint areas for any signs of pain.

The two most common sources of lameness originate in the foot. Laminitis is an inflammation of the hoof wall, usually caused by an improper diet or an infection. A diet too high in grain can cause laminitis as can a diet of grass under stress (grass becomes stressed when it is over gazed or when it has insufficient moisture such as in times of drought). Also, an infection somewhere else on the horse's body could cause laminitis to develop in the foot.

Navicular syndrome, the other most common cause of lameness in horses, also affects the foot. The navicular bone is located at the back of the foot and is an area of tendon and ligament attachment. Being an area where a lot of motion happens, even the slightest inflammation can cause the horse to be lame.

By knowing what signs to look for in your horse you'll be able to detect lameness early. The best treatment is always prevention. By feeding your horse a nutritious diet and seeing a farrier and vet on a regular basis you can prevent most forms of horse lameness.
