Reasons are many for using vetwrap with horses. A huge one is for something we refer to on the track as "rundowns", or competition bandages. Generally also only during racing, or high workout days. The faster a horse goes,or more intense the job asked of a horse, the occurrence of injury or hitting himself with his own hooves becomes great. Another very common occurance with high speed excersice in the horse is called "running down". It occurs more often with hind fetlocks, the horse actually rubs the hair off of the back of his joint, and then a mild or serious burn of the skin can occur against the racetrack surface. Hence the name of the bandages on track being called rundowns. The burn can be serious or severe. Some horses are prone to running down, or hitting themselves due to conformational build, or if a horse that has never run down in the past does run down, it's a sign of emerging soundness issues. Just because a horse wears these, it does not mean it is running with problems, lots of trainers use them as precautionary measure. Here is a picture of the great racemare Zenyatta with a pair of rundown bandages behind. She has tall rundowns on ...
and this horse is wearing short rundowns on his hind fetlocks. If you look closely, you can see the grass rub mark where the horse rubbed his ankle during his race. Most likely the grass was deep and soft as this picture is from England where it rains a lot, and soft turf conditions are commonplace. If this horse wasn't wearing rundowns, he may have burned his skin where that grass stain is on his rundown bandage.
Other uses for vetwrap are to hold bandages in place, and medications on wounds as in this photo of a horse with a foot needing bandaging. Clever addition of duct tape as well..
Since vetwrap is pricey, it tends to be used as only for race day, or when needed medically. For morning exercise works, there are several different material bandages that are used that can be washed and used again, where obviously vetwrap tends to only be used once.
And there is your racehorse/vetwrap lesson for the day...
