PROCEDURE
Apply a halter and leadrope to the horse. Stand on the left side of the horse at the shoulder and facing toward their rear end.
Turn on the hose at low pressure, pointed away from the horse. Then gradually move the stream of water toward the horse. Start by slowly running a gentle stream of water on the left shoulder and elbow area. Gradually move the water stream toward the area of concern, keeping water contact with the horse the whole time.
If the horse moves away, apply pressure on the face with the halter and SIMULTANEOUSLY keep water flow right on the same area. If the horse does not resist, stop the water stream every 10 seconds or so, and reassure them with voice and a gentle pat, then gently restart the water.
Many horses not only tolerate, but learn to enjoy cold water hosing.
TIPS FOR SAFETY AND SUCCESS
It is best to practice this skill on your horse before you need to use it.
Apply a moderate amount of water pressure to an area. Horses usually tolerate pressure quite well, provided it is not excessive or directed on a newly injured or wounded area. Warm water hosing is helpful in treating chronically inflamed areas. For new wounds, use cold water.
Consult with your vet before you hose a wound that might be surgically repaired.
