As we plan for your horse's vaccinations, note that Rabies is considered a CORE vaccination:  that is, every horse should be vaccinated for Rabies, once a year. Rabies vaccination has top priority for several reasons:  

• Rabies is 100% fatal, for animals & for people;  there is no treatment.
• Rabies in horses is fully preventable by an annual vaccination. 
• If unvaccinated, a horse can contract Rabies from various animals including bats, which can be difficult to keep away from stables.
• A horse with Rabies can show a wide variety of symptoms;  it often takes days before the diagnosis is suspected.  Since 2009, in horses which have died of Rabies in Hennepin & Wright counties, symptoms included lameness, colic, & choke.
• The diagnosis of Rabies cannot be made until after the horse has died.  As the owners & helpers handle the sick horse, they are exposed, and may have to undergo the post-exposure Rabies shots.
