On the basis of the animal, amount of work performed by it and the prevailing weather conditions, horses and ponies require routine health check up by a professional veterinarian every 6 to 8 weeks.

All equines suffer from a parasitic burden once in their lifetime therefore it is necessary to offer them periodic treatment throughout life. Animal caretakers usually take care and precautions to keep their prized animals away from this problem. They frequently remove animal droppings from the shed, stall and field, by harrowing or disking droppings in fields, for several weeks in a row, leaving the field empty and by minimizing crowding in fields, they try to curb the menace of parasitic infection in these magnificent animals. Sometimes, animals can also be placed on the field for a period of time other than the equines, such as ruminants as they do not host the same parasitic species as equines.

In order to repel insects, frequent application of fly spray may help which will bring down the incidences of diseases related to botflies. In case any bot eggs are laid in the hair of the horses, using a pumice stone or a specialized bot egg knife can help in curbing this problem. However, if there are internal parasites, to eliminate them a proper check up and follow up treatment is needed. Therefore, to manage parasite problems, most modern horse owners usually give anthelmintic drugs (wormers) to their horses.

Usually two methods of worming are used in case of horses. Using a single strong dose, purge Wormers can be used that kill parasites in a single shot. This medication is administered periodically, in every 8-12 weeks. The dosage also depends on the local conditions and recommendations offered by expert veterinarians. Daily wormers that are also known as continuous wormers are given to the horse in its daily feed in minuscule dosages. These dosages are also very effective in killing parasites. Although, none of the method is completely effective, they offer temporary relief to the horses as the parasites vanish from the body of the horse at least for few days. Since continuous dose is a mild dose, it is repeated periodically and takes longer to show their effect. In case of heavily infected horse, experts usually recommend heavy single dose to control the menace. Normally, on a rotating basis horses require a purge worming with a different drug as neither type of wormers can kill the parasites completely. These wormers are repeated 2-3 times a year. In case a particular drug is unable to kill at least 95% of the parasites, the species is known to be resistant to that drug. Against worms, modern anthelmintics are generally effective but if a horse is heavily infested with parasites, careful administration of wormers must be carried out.
