Is my horse too hot?
tests that may be performed are ultrasonography of the chest and abdomen, abdominocentesis, to get a sample of fluid from the abdomen, or endoscopy to evaluate the respiratory system. The vet may also take samples to rule out infectious causes.
It is often difficult to ascertain the exact cause of pyrexia at the first visit, so you may need to wait for the results of laboratory tests. However, your vet will have narrowed down the list of possible causes and will be able to start some treatment. Initially, fluids and anti-pyretic medication are often given. Vets will not always prescribe antibiotics at the first visit, as they need to ensure that antibiotics are necessary and appropriate. Antibiotics will not help in viral infections and overuse may lead to antibiotic resistance.
Heat stroke:
Heat stroke is a very serious, potentially life-threatening illness. Clinical signs associated with heat stroke in addition to an increased body temperature, include, high heart rate, dullness, reluctance to drink or eat, reduced faecal and urinary output, and ataxia, or weakness and loss of coordination. Oher signs include an irregular heartbeat, flared nostrils, heavy breathing and very prominent veins in the skin.
Heat stroke most commonly occurs due to high intensity exercise in humid environmental conditions. However, it is important to remember that older horses are more vulnerable. And it is not unheard of for animals in a field without shade in the summer to succumb to heatstroke. So even if your horse is no longer an athlete, it does not mean that they are not still at risk. Animals with long hairy coats associated with Cushing’s disease can be more susceptible; as are the heavier breeds, overweight animals or those with dark hair colour. Some stables with poor ventilation can become extremely warm during the summer months. So sometimes being outside with shade and fresh water can be safer.
What should you do if you suspect heat stroke?
Call your vet immediately, your horse may need medical treatment such as intravenous or nasogastric fluids. Signs can progress very quickly. While waiting for the vet, it is important to do everything you can to cool the horse down. The most effective method is to use large volumes of cold water. Scraping the water off is unnecessary, the best thing is to keep pouring the water. Fans or a cool breeze will help, so get them out of a stable if possible. Ice packs and damp rugs are less effective than plain, cold water.
