Run cold water over the affected leg for 10 to 20 minutes, keeping the horse calm and the water steady. Repeat a few times a day as needed, and always have any serious swelling or lameness checked by your vet.
Why cold helps
Cold water reduces blood flow to an area, which eases heat, swelling and inflammation. It is useful after hard work, a knock, or the early stage of a strain, and it is one of the safest first responses to a hot or filled leg.
How to do it
Introduce the water gently at the foot and work up, keeping the horse relaxed. Aim for a steady flow over the affected area for about 10 to 20 minutes. Purpose-made cooling boots are an easy alternative when hosing is not practical.
How often
Cold hose a few times a day for a fresh injury or after hard work. Between sessions, check the leg by hand for heat and swelling to track whether it is improving. Consistency over the first day or two makes the biggest difference.
Know the limits
Cold hosing manages minor heat and swelling, but it is not a cure for a real injury. Persistent heat, swelling or lameness, or any leg that does not improve, needs a proper veterinary diagnosis, as tendon injuries need correct early management.
Stay safe
Keep yourself to the side, do not stand directly behind the leg, and never wrap the hose or lead around your hand. A calm, steady approach keeps both you and the horse relaxed through the treatment.
