Drainage from Anywhere on Body

Summary

Drainage or discharge is different from true bleeding in that the fluid coming from the site is not blood. It might be pus, clear discharge, reddish or yellowish fluid. It may be thick or thin, smooth or lumpy. Normal drainage often results soon after a horse sustains an uncomplicated wound. Drainage also results from an embedded foreign body, a ruptured abscess, or an infected puncture wound. A less likely reason for drainage is a skin condition.

Pigeon Breast and Strangles are conditions typified by abscess formation and drainage. Strangles abscesses are usually found around the throat and under the jaw but abscesses can form anywhere on the body. Pigeon Breast usually causes swelling and drainage around the chest and under-belly but again can be anywhere. Multiple areas of drainage drying on the skin can be seen in certain skin conditions.

What To Do

Assess your horse's general health using the Whole Horse Exam (WHE) paying particular attention to their temperature, attitude and appetite. Describe the color, consistency and smell of drainage. Take a photograph Share your findings and concerns with your vet.

Treat mysterious drainage or discharge as potentially contagious to other horses until you know otherwise, and take action to isolate the horse and contain the discharge. Wear gloves!

What Not To Do

Do not assume that the injury causing the drainage is minor because the injury is small or otherwise not very dramatic.

Injuries near or involving vital structures can be very serious.

  • Do you see an injury, foreign body, or swelling?
  • Tell me more about the color, smell, and quantity of the drainage.
