🐴 THE DISEASES EVERY HORSE OWNER NEEDS TO KNOW
We talk a lot about colic, injuries and lameness.
But there is another category of emergencies that every horse owner needs to understand:
INFECTIOUS DISEASE.
You don't have to own a show horse.
You don't have to board at a large facility.
You don't have to travel constantly.
Any horse can potentially be exposed to infectious disease—and when it happens, recognizing the signs early can make a tremendous difference.
This is why vaccination, quarantine, biosecurity and knowing your horse's normal behavior are so important.
Over the next several posts, we're going to take a deep dive into some of the diseases horse owners should know about.
🐴 STRANGLES
🦠 EHV-1 & EHV-4
🫁 EQUINE INFLUENZA
🦟 WEST NILE VIRUS
🦟 EEE & WEE
🧠 RABIES
🩸 EQUINE INFECTIOUS ANEMIA
🦠 EQUINE VIRAL ARTERITIS
🌡️ POTOMAC HORSE FEVER
🦠 BOTULISM
🫁 RHODOCOCCUS EQUI
🦠 TETANUS
And we'll also discuss important noninfectious emergencies including:
💥 COLIC
🔥 LAMINITIS
☀️ HEAT STRESS
🩸 SEVERE WOUNDS
👁️ EYE EMERGENCIES
🦴 FRACTURES & SEVERE LAMENESS
😮💨 CHOKE
Because knowing the name of a disease isn't enough.
You need to understand:
WHAT DOES IT DO TO THE BODY?
HOW DOES IT SPREAD?
WHAT DOES IT LOOK LIKE IN THE BEGINNING?
WHAT ARE THE RED FLAGS?
CAN IT BE PREVENTED?
WHEN SHOULD YOU ISOLATE THE HORSE?
WHEN SHOULD YOU CALL YOUR VETERINARIAN?
And perhaps most importantly:
HOW DO YOU KEEP IT FROM SPREADING TO THE REST OF YOUR HORSES?
Vaccination is an important part of prevention, but it isn't the entire picture. The AAEP currently identifies tetanus, EEE/WEE, West Nile virus and rabies as core equine vaccines, while other vaccines—including those for strangles, influenza and EHV—are selected according to the individual horse's risk and circumstances.
This isn't about creating fear.
It's about creating educated horse owners.
Because sometimes the difference between:
"Something doesn't look right."
and
"I know something is wrong, and I know what information my veterinarian needs."
is education.
🐴 KNOW YOUR HORSE.
🩺 KNOW YOUR VETERINARIAN.
💉 KEEP VACCINATIONS CURRENT.
🧼 PRACTICE BIOSECURITY.
🚨 HAVE AN EMERGENCY PLAN.
And when something doesn't look right—
CALL YOUR VETERINARIAN.
Educational information only. Disease diagnosis and treatment should always be directed by a veterinarian.
