Strangles, also known as equine distemper, is a highly contagious bacterial infection affecting horses of all ages and breeds. Early detection is crucial for effective treatment and preventing the spread of this debilitating disease. Recognizing the first signs of strangles is paramount for horse owners and equine professionals alike. This comprehensive guide will delve into the initial symptoms, helping you understand what to look for and when to seek veterinary attention.
What are the typical first signs of strangles?
The initial symptoms of strangles are often subtle and easily overlooked, making early diagnosis challenging. Common early signs include:
-
Mild Fever: A slightly elevated temperature (101-102°F) is often one of the first indicators. This may be accompanied by lethargy or a general feeling of malaise. The horse may seem less energetic than usual or less interested in its usual activities.
-
Nasal Discharge: A thin, watery discharge from one or both nostrils is another early warning sign. This discharge can progress to become thicker and more mucopurulent (containing pus) as the infection advances. Initially, it might be clear or slightly cloudy, a key difference from the later stages.
-
Swollen Lymph Nodes: Enlarged lymph nodes, particularly those under the jaw (submandibular lymph nodes), are a hallmark symptom of strangles. These swollen glands may feel warm and tender to the touch. The swelling can range from mild to severe, causing noticeable distension in the throat area.
-
Loss of Appetite: A decreased appetite is another common early sign. The horse may be less interested in food and may refuse to eat entirely in more advanced stages.
-
Cough: A mild, dry cough may be present in the early stages, often developing alongside other symptoms. This cough can become more severe as the disease progresses.
How quickly do strangles symptoms develop?
The incubation period for strangles, the time between infection and the onset of clinical signs, is typically 4-14 days. However, this can vary depending on the horse's individual immune response and the infectious dose. Symptoms may develop gradually or more suddenly. Some horses might exhibit only mild symptoms, while others experience a more severe form of the disease.
What are some less common early signs of strangles?
While the symptoms mentioned above are the most common early indicators, some horses might display less typical signs:
-
Depression: A noticeable change in the horse’s demeanor, exhibiting signs of depression or listlessness.
-
Abscess Formation: In some cases, small abscesses can form in the lymph nodes before the swelling becomes dramatically noticeable. These abscesses may rupture and drain pus.
When should I call the vet about suspected strangles?
If you suspect your horse has strangles, contact your veterinarian immediately. Do not delay treatment. Prompt veterinary intervention is essential for managing the infection, preventing its spread to other horses, and improving the prognosis. Your veterinarian will conduct a thorough examination and may perform diagnostic tests to confirm the diagnosis. Early treatment can significantly reduce the severity of the illness and the risk of complications.
What if my horse has already shown severe symptoms?
If your horse is showing more advanced symptoms like severe swelling, difficulty breathing, or significant lethargy, seek immediate veterinary attention. This is a veterinary emergency.
