Horses are part of an ever growing industry, with over 600,000 horses in the UK, 1.4 million riders and 5 million people with an active interest in the equine industry*. Most people acquire a horse out of choice, so if you make this decision you should think carefully before going ahead. A horse needs lots of love and care, including regular worming, vaccinations and dental care. Owning a horse is time consuming and can be costly; not only will you will need to consider where you will keep your horse, you must also consider the ongoing costs of owning a horse which include accommodation, bedding, feed and healthcare.
In the unlikely event that your horse goes missing it is going to be very difficult for anyone to know who it belongs to, unless your horse carries some form of permanent identification. It is wise to get your horse microchipped or freezemarked, this will avoid heartache in the long run, should your horse go missing or is stolen.
Horses are herd animals, and thrive on being together with other horses. Don’t forget that your horse will need somewhere to graze, a stable for warmth in the winter time, a constant supply of water, feeding daily and regular exercise. It can cost hundreds of pounds a month to care for a horse, including accommodation, food, veterinary care and insurance; there will be other costs, including buying tack and rugs and extra livery charges when you go on holiday.
Horses can live into their thirties, over this time your horse will need lots of care and attention. Being able to provide all of this will ensure you and your horse make the most of your time together.

West Nile Virus - what owners should know
West Nile Virus (WNV) is a viral disease previously only seen in Africa, western Asia, and southern Europe. Now it can also be found in the Middle East, Mediterranean region of Europe and the US. Prevention is the name of the game, so make sure you are one step ahead and protect your horse from this life-threatening disease.
What is West Nile Virus?
West Nile Virus (WNV) is a viral disease that can cause encephalitis, an infection of the brain and the spinal cord. WNV is spread by the bite of an infected mosquito that acquires the virus from infected birds. The principal transmitter of WNV is the Northern House Mosquito (Culex pipiens). The incubation period of the WNV infection is usually 5-15 days.
Many birds can be infected with WNV, but crows and blue jays are most likely to die from the infection. Horses, too, are prone to severe WNV infection. Although horses may be infected by the virus, there is no evidence that infected horses can spread the virus to uninfected horses or other animals. However, if at all possible, horses with suspected West Nile Virus should be isolated from mosquitoes and tested for the virus.
In recent years WNV has caused widespread disease in the United States with numbers of reported cases fluctuating over the last 10 years. However, cases have slowly declined since 2003 where over 5100 cases were reported. In 2016, a total of 377 equine WNV cases were reported in 32 states, with Texas and Washington being the most highly affected states.
What are the clinical signs of WNV?
In horses that become clinically ill, the virus infects the central nervous system and causes symptoms of encephalitis. Clinical signs of encephalitis in horses include:
- Ataxia (incoordination).
- Loss of appetite.
- Partial paralysis.
- Weakness of limbs.
Other diseases can cause a horse to have symptoms similar to WNV, including:
- Equine protozoal myeloencephalitis (EPM).
- Neurologic equine herpesvirus-1 infections.
- Other mosquito-borne viral encephalitic diseases caused by Eastern, Western, and Venezuelan encephalitis viruses.
If you are worried that your horse may be exhibiting signs of encephalitis, contact your veterinarian immediately. Only laboratory tests can confirm the diagnosis of WNV.
How can I prevent my horse from contracting WNV?
There is a new vaccine available against West Nile Virus. Your horse must be vaccinated twice initially, three to six weeks apart, with this vaccine. The use of this vaccine, however, is restricted, so you will need to contact your vet to find out if the vaccine is available for use in your area.
Remember: Horses vaccinated against Eastern, Western, and Venezuelan equine encephalitis are NOT protected against WNV.
Currently, there is no specific treatment for WNV in horses, so prevention is essential (supportive veterinary care is recommended).
You can decrease the chances of your horse being exposed to WNV by taking preventative steps, eg:
- Avoid turning on lights inside the stable during the evening and overnight as they will attract mosquitoes.
- Keep an eye out for dead birds, such as crows, they should be reported to the local health department. Use gloves to handle dead birds.
- Place bright lights outside the stable to attract mosquitoes away from your horse.
- Remove all birds, including chickens, that are in or close to the stable.
- Remove any sources of water where mosquitoes may breed, eg shallow standing water, used tires, manure storage pits, drainage areas with stagnant water. Note: Mosquitoes can breed in any water that stands for more than 4 days.
- Stable your horse during periods of mosquito activity, ie dusk and dawn.
- Use mosquito repellents available for use on horses. Make sure you read the product label before using and follow all instructions.
The Department for Environmental Protection, local Department of Health, local veterinarian or mosquito and pest control company will be able to help with assessing mosquito exposure risks on your property and suggest appropriate control methods.
