Equine Lyme disease is a growing concern for horses in North America, especially during the summer months when tick bites are more common. Lyme disease is primarily caused by infection with Borrelia burgdorferi, a bacteria that is carried by ixodid, or hard-bodied, ticks. You may recognize this tick by its more popular name, the black-legged or deer tick (Ixodes scapularis).
Equine odontoclastic tooth resorption and hypercementosis (EOTRH) is a progressive and painful dental condition that occurs in some horses. Primarily affecting senior horses, it typically involves the gradual degeneration of the incisors and canine teeth. Over time, the roots of these teeth are resorbed or dissolved.
Diarrhea can affect horses of all ages, breeds and sizes, resulting in dehydration, weight loss, poor nutrient absorption or electrolyte imbalance. Diarrhea is described as the increased excretion of liquid or semi-solid feces. Cases of equine diarrhea can range in severity from mild episodes to serious and long-term episodes, which may require veterinary attention.
Internal parasites, also known colloquially as worms, are a common concern for many horse owners. Parasites are organisms that live on the horse’s skin or infiltrate the intestinal tract to gain nutrients. They can cause inflammation, immune problems, ulcers, and, in serious cases, impaction of the intestines.
Lameness in the horse's stifle joint can result in shortened stride length, reluctance to work or a rough canter. While lameness is more commonly attributed to problems with the hock joint, stifle lameness is seen frequently in performance horses. The stifle is considered the most complex joint in the horse's body with a similar function to the human knee. Stifle injuries can result from repetitive stress, trauma, excessive use, changes in direction and rapid deceleration. Horses engaged in jumping and barrel racing are most at risk of these injuries.
