If you suspect your horse has an abscess you must first consult your Farrier or veterinary surgeon to come and find the abscess. An abscess is a collection of pus that has accumulated in a cavity formed by the tissue in which the pus resides due to an infectious process or other foreign materials and in some cases may require antibiotics to treat the infection. Once the abscess has been found here is a step by step guide on how to poultice a horses foot. Step 1. Optional, Hot tubbing Hot tubing is used to draw pus from a foot by placing the foot in a bucket of warm water with Epsom salts mixed into the water for around 10-15 minutes Make the water around 38ºC. The heat from the water will soften the area around the pus hopefully allowing to burst open and drain. Even after an abscess has been opened hot tubbing can be a good way to draw and flush out the remaining pus.Step 2. Materials used to poultice a foot.All these materials used are all off the shelf items from any good equestrian shop and always handy to have around.. Epsom salts. Animalintex. Vet wrap. tape. (I find the silver or black fibre tape the best to use.) . scissors Step 3.After finding the area of the abscess and hot tubbing, cut a square of the Animalintex much larger than the area so it is covered well. Animalintex can be used dry or wet, if a wet poultice is required Use boiled water that has been allowed to cool to 38ºC and pour the water into a tray, around the edges of the Animalintex, ring off the excess water and place over infected area. Always have the plastic side of the Animalintex outward away from the foot whether using wet or dry.Step 4.After Animalintex is in position begin to wrap around the foot, try to stay just on the hoof wall avoiding covering past the hair line. keep wrap until the whole underside has a layer of vet wrap. To finish cut off the rest of the roll and smooth over with your hands.Step 5.After applying van wrap layer repeat with the tape again avoiding going over the hair line. Use more layers over the bottom of the foot to prevent the horse wearing through it when its walking. If any tape has got over the hair line remove and excess with the scissors.
