I tell veterinary students that to recognize a sick or lame horse, they need to look at a lot of healthy, sound horses. Horses vary, but there are signs of general good health that apply to all.

Healthy horses are bright and alert, and interested in other horses, you and their surroundings. They will roll occasionally, especially after being turned out, but always shake the dust off after rolling. A horse that rolls over and over and often looks at its side might be experiencing signs of colic. Contact your veterinarian.


The No.1 sign of an infectious disease like influenza or West Nile virus is the horse has a decreased appetite or refuses to eat. In some cases, teeth problems may prevent eating, so to differentiate, take the horse's rectal temperature. An adult horse at rest should have a body temperature of 99 - 101.5 degrees Fahrenheit. Anything above that level can indicate an active infection. The normal temperature range for a foal is 99.5 - 102.1 degrees Fahrenheit.

Eyes and noses

Your horse's eyes should be clear, fully open and clean, not cloudy or discolored. Any indications of an unusual discharge or a dull glazed appearance should be looked into by your veterinarian. The nostrils should be clean and free of excessive mucus. However, it is normal for a horse to have a trickle of clear liquid from the nostrils.

Weight and body condition

You should ensure that your horses maintain optimum body condition and not let them get too fat or too thin, as each presents health risks. Use the Henneke Body Condition nine-level scoring system to evaluate your horse's body condition. A body condition score of 4-5 is ideal.

Hair coat

A shiny, glowing coat is a sign of good health that comes from meeting the horse's nutritional requirements and frequent grooming. A dull coat can be a sign of poor nutrition, parasites or general poor health.

Vital signs

It's important that you know your horse's vital signs, as they are early indications of a problem. If the horse is excited or it's a hot/humid day, heart and respiration rates can be slightly elevated:

  • Heart rate: 28-44 beats per minute depending on the horse's size.
  • Respiration: 10-24 breaths per minute.
  • Mucous membranes: The horse's gums should be moist and a healthy pink.
  • Capillary refill time: If you press your finger firmly against the horse's gums, the point of pressure should return to a pink color within one to two seconds.
  • Intestinal sounds: Gurgling, gas-like growls, tinkling sounds and occasional roars are normal. No intestinal sounds or decreased intestinal sounds can be a sign of colic.

Manure and urine

A healthy horse will pass manure eight to 12 times a day. Urine should be wheat-colored and either clear or slightly cloudy.


The average horse drinks between five and 10 gallons of water a day, depending on exercise level and weather conditions.

Legs and feet

The horse should stand squarely with its weight evenly distributed over all four feet. Slightly raising and taking the weight off a hind leg is normal, but not for a foreleg. Your horse's legs should be free of bumps, swelling, cuts or hair loss. There should be no heat in the horse's feet.

A quick evaluation of your horse can be done in less than 10 minutes. Check him daily so you will know what is normal and what is not.
