How do you take care of horse wounds?

Wound care depends entirely on the wound.

If the wound is open and/or infected, you need to call your vet immediately to have it looked at and cleaned.

If the wound is smaller (like a bite wound or a scrap from something) then make sure to simply keep it clean. You can try spraying an antiseptic on it to keep it from getting infected, but the most important thing is to keep it clean and to keep flies away from it so that it can heal.

If you can't see the wound (for example, horse is limping with no apparent reason), and you can't figure out what is causing your horse's pain, it's best to call someone who would be able to check the horse out (either a barn manager, trainer or the vet). It is always better of being safe than sorry, especially with an animal as large as a horse.
