Urine appears Clear Like Water


Horses that are well hydrated produce large volumes of relatively clear (dilute) urine. Many stabled horses drink more water than they need to (a habitual problem), and much of that water is lost as dilute urine. Very clear urine is also typical of well hydrated young foals.

However, dilute urine in the face of poor hydration is a sign of kidney failure. Horses with kidney failure typically act depressed or lethargic and also have a poor appetite.

What To Do

Assess the horse's general health using the Whole Horse Exam (WHE), paying particular attention to attitude and appetite. If the horse seems well otherwise, clear urine alone is probably not a cause for concern. However, if accompanied by other signs of illness or disease, contact your vet with your findings and concerns.

What Not To Do

Do not restrict access to water.

your vet's role

Your vet uses history and physical examination to determine general health. Blood work and urinalysis add vital information. Your vet may also ask you to determine how much water your horse is drinking. In this case, you will need to use buckets instead of an automatic waterer.
Questions Your Vet Might Ask:
  • How is your horse's attitude and appetite?
  • How is the horse stabled or managed?
  • How long has the horse been stabled this way?
  • How much water is your horse drinking per day?
  • Are you supplementing feed or water with electrolytes?
  • What are the results of the Whole Horse Exam (WHE)?
