Two Questions from My Client Equine Owners

I’m often asked similar questions by animal owners dealing with health of their animals. Taking care of large animals is what I love to do, so answering these questions is always a pleasure. The following are two common questions I sometimes get. [emember_protected custom_msg=”Click here and register now to read the rest of the article!”]

How often should you deworm your horse?

The best way to decide how often to deworm your horse is by performing a fecal test twice a year to determine your horse’s parasite burden. Depending on the results, your horse will be classified as a high, medium or low egg shedder. Climate, environment, and number of horses on the property also will contribute to your horse’s deworming strategy. With any deworming plan, rotation of deworming products is critical in minimizing parasite resistance. Deworming plans differ between farms, so consult with your veterinarian to make sure you have the right plan in place.

How are West Nile Virus and Eastern Equine Encephalitis (EEE) transmitted?

West Nile Virus and Eastern Equine Encephalitis are mosquito–borne viruses. Birds in the crow and jay family are thought to be the most common carriers of WNV and EEE, although some other species, including songbirds and waterfowl, may be carriers as well. Mosquitoes transmit the virus to horses, other birds and other mammals, including humans. WNV/EEE is not transferred from horse-to-horse or horse-to-human.
