Sarcoids in Horses: Types, Causes, Prevention & Treatment

By |2023-01-26T14:42:04-05:00January 26th, 2023|Conditions|

Of the many skin conditions horses can develop, sarcoids are the most common. The term "sarcoid" was first used in 1936 in South Africa as a way to distinguish this skin lesion from other tumors. Sarcoids are benign (nonmetastatic) skin cancer believed to be caused by papillomavirus infection. They affect up to 11.5% of all horses. Sarcoids usually appear as rough, raised, hairless patches or nodules on the skin that are not painful or itchy. Some sarcoids are protruding, moveable masses with overlying skin still intact. The tumors are cosmetically unappealing and, depending on their location, can interfere with the function of the horse. But in most cases, the prognosis for affected horses is very good and some sarcoids resolve without any intervention. Effective treatments are available, including surgical removal, immunotherapy, cryotherapy, and laser surgery. However, sarcoids have a high rate of recurrence in horses.

Myofibrillar Myopathy (MFM) in Horses: Signs, Diagnosis, Management & Prognosis

By |2023-01-26T11:28:45-05:00January 26th, 2023|Conditions|

Myofibrillar myopathy (MFM) is a newly identified muscle disorder that causes exercise intolerance in horses. MFM is a genetic condition that results from the abnormal build-up of desmin in muscle tissue. Desmin is a protein that is important for muscle contraction. In response to strenuous exercise, horses with MFM may experience pain, stiffness, lameness, poor stamina and intermittent gait abnormalities. This disorder has been identified mostly in Warmblood, Arabian horses and their crosses. Affected Warmbloods often refuse to collect under saddle while Arabians tend to have episodes of tying-up or extreme cramping.

Slobbers in Horses: Slaframine Poisoning Signs, Causes & Treatment

By |2023-01-25T09:47:47-05:00January 25th, 2023|Conditions|

Slobbers, otherwise known as slaframine poisoning or salivary syndrome, is a condition that causes excessive salivation or drooling in horses. It is relatively rare and usually occurs in outbreaks, with multiple horses affected at once. Slaframine intoxication is caused by horses consuming a fungus that grows on legume forages under wet and humid conditions. Horses who ingest infected pasture, hay or silage can develop clinical signs, including hypersalivation and difficulty swallowing. While many animals are affected by this fungus, horses are particularly sensitive. Outbreaks of slobbers have occurred in humid climates, including North America, Europe and South America. Slobbers is non-life threatening, but the drool hanging from an affected horse’s mouth is unsightly and can be a nuisance.

Glycogen Branching Enzyme Deficiency (GBED) in Horses

By |2023-01-24T10:43:45-05:00January 24th, 2023|Conditions|

Glycogen branching enzyme deficiency (GBED) is a fatal disorder caused by a gene mutation found in the Quarter Horse and Paint Horse bloodlines. GBED causes abortion in late-term pregnancies, stillbirth or severe muscle weakness and eventually death in newborn foals. GBED prevents foals from properly storing sugars in the body. As a result, there is not enough energy to fuel the important organs and muscles of the body. This causes severe weakness and other clinical signs. Genetic testing for diseases is required for most QH and APH horses in breeding programs to ensure healthy offspring and prevent financial loss associated with losing a foal.

Black Walnut Tree Poisoning in Horses: Symptoms & Treatment

By |2023-01-17T10:21:31-05:00January 17th, 2023|Horse Health|

Black walnut tree poisoning occurs when horses come into contact with toxic compounds in the black walnut (Juglans nigra) tree. The roots, bark, wood, nuts, pollen and leaves of the tree contain a chemical that is poisonous to horses upon ingestion or skin contact. Horses are particularly at risk of poisoning from exposure to black walnut shavings. The hardwood shavings of the tree are sold as animal bedding in North America. Horses that come into contact with black walnut shavings, sawdust or tree materials can develop mild to severe symptoms and acute laminitis in only a few hours.

16 Common Skin Diseases in Horses: Identification & Treatment

By |2023-01-13T15:04:31-05:00January 13th, 2023|Conditions|

Horses are prone to a number of different skin conditions and diseases. Some are minor and resolve on their own, while others can be much more serious. Skin conditions may affect localized areas on the horse, such as the legs or abdomen, or they can be widespread, affecting multiple areas. Symptoms may include itchiness, swelling, hair loss, skin flaking, and more. Learning to recognize various equine skin diseases is important to take the appropriate actions needed to resolve the problem or to manage the horse to keep them more comfortable.

Testing your Horse’s Water Quality: Safety & Management

By |2023-01-12T13:52:36-05:00January 12th, 2023|Care & Management, Horse Health|

Water is the most vital component of the equine diet, but it is often overlooked when considering your horse's nutritional needs. Hydration influences several aspects of horse health, including exercise tolerance, digestion, and temperature regulation. Not only do you need to ensure that your horse drinks enough water, but also that your horse has good quality water available. Testing water quality helps to determine whether your horse's water supply is safe for consumption and whether you need to consider a water treatment or filtration system. A water analysis will also tell you about the mineral levels present. This can help you address any potential dietary imbalances caused by water intake.

Equine Grass Sickness: Symptoms, Treatment & Prevention

By |2023-01-23T14:49:01-05:00January 9th, 2023|Conditions|

Equine grass sickness (EGS), or equine dysautonomia, is a rare and fatal disease in horses. It almost exclusively affects grazing horses kept on pasture. EGS is characterized by the development of severe lesions on the neurons of the peripheral and central nervous systems. Symptoms vary in severity depending on the neuronal degeneration in the horse. EGS results in loss of normal function of the gastrointestinal tract, affecting the horse’s ability to swallow and digest food.This disease results in a decrease in gut motility, increasing the risk of colic and causing severe weight loss. Although the exact cause of EGS is unknown, it is believed to result from a combination of environmental factors and bacterial infection.

Pain Management in Horses: Signs, Treatments & Therapies

By |2023-01-03T16:10:15-05:00January 3rd, 2023|Conditions|

Pain is something that all horses deal with at some point in their lives. Horses can experience pain for many different reasons, including injury, illness, or a result of surgery. For example, castration is the most common surgical procedure performed on horses and is associated with significant post-operative pain. Acute colic is another common painful experience for horses. Pain is also commonly associated with degenerative joint disease, laminitis, gastric ulcers, and hoof issues. Unlike humans, horses don't always show it when they are experiencing pain, or they may only display subtle signs of discomfort. This is because, as prey animals, they have evolved to hide signs of pain and weakness in the presence of predators.

Stringhalt in Horses: Causes, Symptoms & Treatment

By |2022-12-22T12:25:07-05:00December 22nd, 2022|Conditions|

Stringhalt, or equine reflex hypertonia, is a neuromuscular condition that causes abnormal hindlimb movement in the horse. Horses with stringhalt have excessive and prolonged flexion of the pelvic limbs while in forward movement, showing signs of the condition at most gaits. One (unilateral) or both (bilateral) legs may be affected. Some horses experience mild cases characterized by involuntary jerking of the hindlimb, while others experience lameness and difficulty standing up. Horses of all ages and breeds can be affected by stringhalt. In some cases, it is caused by ingesting toxic plants at pasture, but other cases develop quickly without apparent cause.

Bone Spavin in Horses: Symptoms, Treatment & Management

By |2022-12-19T13:42:05-05:00December 19th, 2022|Conditions|

Bone spavin, also known as Degenerative Joint Disease (DJD) of the hock (tarsus), is an extremely common cause of equine lameness. It is caused by repeated concussion and rotational forces on the hock joint, as well as excessive forces on the adjoining ligaments. As a wear and tear condition, bone spavin is characterized by narrowed joint spaces and bone spurs. It is frequently bilateral and accompanied by lameness, with a decreased range of motion.

Equine Soundness: How to Tell if Your Horse is Sound?

By |2022-12-20T11:25:50-05:00December 19th, 2022|Horse Health|

What does it mean to have a sound horse? The term 'soundness' is used by horse owners to describe how a horse moves. For example, a horse is not sound if they are limping or there is a deviation in their gait. However, soundness refers to much more than just movement. It also encompasses a horse's overall health and wellness and ability to perform the job they are meant to do. Horses are considered perfectly sound if they have no health issues and move perfectly without veterinary intervention (i.e. injections or pain control). As you can imagine, perfectly sound horses that never require intervention are very rare. A horse may be perfectly sound for only a short period of its life.

Common Antibiotics for Horses: Oral, Injectable & IV Drugs [List]

By |2022-12-20T11:07:19-05:00December 9th, 2022|Horse Health|

Antibiotics or antimicrobial drugs are effective medications for the treatment of bacterial infections in horses. Common equine infections requiring antibiotics include infected skin wounds and abscesses, pneumonia, infectious diarrhea, cellulitis, peritonitis and more. Many antibiotics have broad-spectrum action meaning they act against many different bacteria. Others more specifically target certain bacterial strains. Your veterinarian can determine which antibiotic is appropriate for your horse given their medical situation. These drugs are not without risks, and they can have adverse effects on horse health when given without veterinary oversight.

Equine Herpesvirus Infection: Symptoms, Treatment & Prevention

By |2022-12-20T11:11:51-05:00December 7th, 2022|Conditions|

Equine herpesvirus (EHV), or rhinopneumonitis, is a contagious infection that is endemic to horses worldwide. EHV may cause mild to severe symptoms that usually involve the upper respiratory tract. In rare cases, it may cause neurological symptoms, abortion or death. Horses can experience latent infections of EHV where the virus lives dormant without causing symptoms. There are nine known types of herpes viruses in horses, of which EHV-1 and EHV-4 are the most common. EHV-1 usually results in more severe symptoms but EHV-4 is more common.

Botflies in Horses: Symptoms, Prevention & Treatment

By |2022-12-01T16:43:02-05:00December 1st, 2022|Conditions|

Botflies (Gasterophilus spp) are parasitic flies that affect the horse's digestive tract and can cause negative health consequences. Botflies lay eggs on the horse's coat in the summer. Some of these eggs, known as horse bots, are ingested as the horse licks and grooms itself. The bot eggs hatch and the larvae develop in the horse's mouth before migrating to the stomach where they attach to the gastric mucosa. Once mature, they detach and are passed through the manure. They pupate into flies, and the cycle repeats with new botflies seeking out horses to host their eggs.

Coconut Oil for Horses: Nutrition, Benefits & How to Feed [Review]

By |2022-11-30T13:47:07-05:00November 30th, 2022|Horse Health|

Coconut oil is a popular fat supplement for horses used to promote weight gain, skin health and a shiny coat. It is also used as a cool energy source for exercising horses to add calories to the diet without relying on sugars and starches. Coconut oil is derived from the kernel of mature coconuts that are harvested from the coconut palm tree. The two main types of oil obtained from coconuts are copra oil and virgin coconut oil. High-fat equine feeds are typically made with vegetable fats derived from canola, rice bran, soybean, and flax, but a growing number of products are now using coconut oil as an ingredient.

Can Hair Analysis Determine your Horse’s Mineral Status?

By |2022-11-23T13:11:26-05:00November 21st, 2022|Horse Health, Nutrition|

Is hair analysis a reliable way to evaluate your horse's mineral status? Mineral testing is an important aspect of monitoring your horse's health, especially if forages in your area are known to be deficient or excessive in a given nutrient. Horses with certain medical conditions may also need frequent monitoring of mineral levels. In horses, mineral status is most commonly assessed through blood testing, hair samples or by evaluating intake with a forage analysis. These methods each have advantages and disadvantages that impact their usefulness. Hair sample analysis is convenient, but few reference ranges have been established for mineral levels in equine hair, making interpretation of results difficult.

Equine COPD: Signs, Causes, Diagnosis & Treatment

By |2022-11-21T09:17:05-05:00November 21st, 2022|Conditions|

Equine COPD - or chronic obstructive pulmonary disease - is a now-obsolete term for a common condition in horses that causes coughing and poor performance. This condition is now referred to as equine asthma and is one of the most common non-infectious lung diseases. Severe equine asthma affects 14–17% of horses in some populations, but up to 70% of pleasure horses have indicators of mild to moderate asthma. Horses affected by equine asthma typically have increased mucus production, difficulty breathing during exercise and sometimes at rest, cough, and nasal discharge. More severe cases may result in acute respiratory distress.

Lymphangitis in Horses: Symptoms, Causes, Treatment & Recovery

By |2022-11-15T15:23:18-05:00November 15th, 2022|Horse Health|

Lymphangitis, also known as big leg disease or stovepipe leg, is a condition in horses involving inflammation of the lymph vessels, most often in the lower limb. Lymphangitis presents as extreme swelling with rapid onset, resulting in pain in the lower leg, reluctance to bear weight, lethargy, lack of appetite, and sometimes fever. This condition is caused by bacterial or fungal infection, usually following a wound to the leg. The infection can also result in very painful sores or lumps on the leg and cracking of high-motion skin areas (such as the fetlock). Seek veterinary care immediately if you suspect your horse has lymphangitis. If left unaddressed, the infection can spread to other organs and cause internal abscesses or sepsis, a potentially life-threatening condition.

Equine Asthma: Symptoms, Diagnosis, Treatment & Management

By |2022-11-14T12:33:32-05:00November 14th, 2022|Conditions|

Equine asthma (EA) is a relatively new collective term for chronic respiratory signs in horses that range in severity from mild to severe. These conditions were previously known as inflammatory airway disease (IAD) or recurrent airway obstruction (RAO), respectively. Equine asthma is characterized by inflammation and mucous production in the lungs, which leads to lower airway obstruction. The horse may cough, and breathing may or may not be laboured. Asthma is most commonly observed in horses stabled over winter months that have become hypersensitive to dust, airborne allergens, mold spores, or mites in stable bedding or stored hay.
