Whether or not to call the veterinarian is a dilemma all observant horse owners face on a regular basis. Fortunately a few guidelines can make the decision-making process a little easier. The University of Florida Large Animal Hospital College of Veterinary Medicine has provided an extensive list that addresses the signs and conditions that indicate "It's Time to Call the Vet."

If you have concerns about your horse’s condition, it is better to call your veterinarian because earlier diagnosis and treatment helps provide you and your horse with the best possible outcome.

Although certain illnesses and conditions will have obvious signs and indicators that a veterinarian should be called, others may not. It is critical to know the normal behavior, attitude, and gait of your horses, since changes that could require veterinary attention may be subtle at first.
No one knows your horse better than you. Learn how to take your horse’s heart rate (normal 28-48 beats per minute), respiratory rate (10-20 breaths per minute), and temperature (99-101.5 F), and know the normal values for your horse. Be familiar with normal gum color (light pink) and capillary refill time (less than 2 seconds). Understanding what is normal for your horse will help you identify subtle changes and will help improve communication with your veterinarian should an issue arise.
Equally important as knowing when to call your vet, is having a plan for emergencies. Keep important phone numbers readily available, have a plan for transportation if your horse requires a referral to a hospital, and keep a first aid kit on the farm and in your trailer.
Consider discussing a backup veterinarian with your vet in case they are unavailable. Keeping directions and maps available to local veterinary hospitals may help expedite travel should that be necessary. Most importantly, remember to stay calm and call your vet sooner rather than later if you suspect a problem.
Specific Symptoms and Conditions
Call the vet if your horse has:

- Temperatures over 103 o F indicate a serious problem and your horse should be placed in a cool area with fans and hosed off until the vet arrives
- Abnormal gum color (red, purple, white, or yellow)
- Squinting, swollen, cloudy or tearing eye
- Yellow or green nasal discharge
- Loss of appetite or difficulty eating
