How do I stop blanket rubs on shoulders and mane?

Penn State Extension says horses can develop rub marks or sores where blanket straps fit badly, and Practical Horseman's groom calls poor fit one of the most common causes of shoulder rubs. Most fixes start with the blanket, not with a product to stick under it.

The honest part is that horse people disagree about the add-ons. Some swear by shoulder guards and bibs, some say a guard caused them trouble, and the sources we read do not agree on which lining is best. We lay out both sides below, so you can decide with your horse in front of you.

Hair loss and sores are the signal to look closer. If a rub has broken the skin, or he is losing hair where the blanket doesn't touch him, call your vet.

Horse & Rider says hair loss appears where the blanket rubs as the horse moves, mainly on the shoulders and withers. Practical Horseman adds the backs of the hind legs and names two other causes: heat and a skin condition. A blanket that is too heavy, or one put on too soon after exercise, can leave him sweating under it, which makes friction worse. Hair loss or sores in places the blanket does not touch point to a skin problem a vet should rule out.

Rutgers Equine Science Center says ill-fitting blankets can cause sores on the withers and rubs on the shoulders. For the mane, the cause is usually a neck cover or high neck that is too tight, dragging the hair, or too loose, sliding as he grazes. That is the point our neck covers and hoods guide makes.

That is the University of Maine bulletin's test, and it adds that fit varies by brand, so a size that works in one line can pinch in the next.

Practical Horseman's groom gives a fuller routine. Close the chest first, then work back to the belly and leg straps. Check that the front edge covers the withers and shoulders without gapping. Keep each belly strap snug enough to fit only one hand width between it and the horse. Keep leg straps off the hocks and loop them rather than crossing them. And watch him move, because a restrictive blanket can change his gait.

To measure, our horse blanket sizing guide walks through it, and our horse blanket guide lists the fit checks. Try the cut page if you suspect the shape, not the size, is wrong.

Practical Horseman describes gussets as extra panels of material that allow more freedom of movement, with higher placement giving more. It also says a wraparound chest closure seems to reduce the incidence of shoulder rubs. For high withers, our blanket cut page explains the high-neck and combo cuts and why a straight cut can pull across the withers.

Riders say the same thing in their own words. This one is a single rider's fix for withers that pull the blanket up against the shoulders. Horses vary, but it matches the cut advice above, and a second rider's account of bigger shoulder gussets follows in the next section.

Practical Horseman's groom says nylon linings create fewer rubs than textured materials, and suggests stitching nylon or felt inside the blanket where it meets the shoulders if it has none. She also suggests a slick nylon undergarment so the blanket slides, and says to choose one whose neck edge sits in front of the blanket's, so the edges do not overlap and chafe.

Horse & Rider takes a different line on material. It suggests sewing thick fleece inside the blanket over the rub areas, or using a tight lycra underlayer, and says either one prevents further follicle damage that could cause discoloration or permanent hair loss. It also says that hard-to-fit horses may rub even in a well-fitted blanket. So one source puts smooth nylon inside, another puts fleece inside, and both put a lycra-type layer on top of the horse.

Bibs and shoulder guards get recommended widely, but the extension and magazine sources we read do not test them, so most of the evidence is what riders report. One rider's account shows why caution is fair, and why she credits the gussets:

Our neck covers and hoods guide says a cover that is too tight drags the mane and one that is too loose slides and rubs as the horse grazes. It also says to look for a smooth lining and a fastening that cannot twist at the withers, and to size up or switch cuts if you see broken hair along the crest.

Horses with long manes and thick, high necks wear a cover hardest. Our neck cover page covers when he needs one at all. A neck that stays warm and dry in a standard blanket can usually skip the cover and its rub risk.

Rutgers recommends removing it at least weekly to groom and check, and University of Maine and Penn State say to inspect for rub spots, damage and twisting. Here is how that looks in practice.

Run your hand over the point of the shoulder, the withers, the crest and, if he wears leg straps, the backs of his hind legs. Look for broken or dull hair, and feel for heat, swelling or a sore spot. Check the straps and the blanket's front edge for how they sit. Then look at his weight, because University of Maine says to use the check to keep an eye on body condition too.

If the hair is just a bit rubbed, change the blanket's fit or cut and check again in a week. If you see broken skin, swelling or hair loss spreading, call your vet before putting a blanket back on.

The sources we read suggest keeping the blanket off the area until the hair and skin recover. Practical Horseman's groom recommends a heavy coat of diaper-rash ointment on the rubs, with more cleaning, but that is one groom's practice, not a veterinary protocol, so ask your vet what is right for his skin.

Rutgers says to remove blankets at least once a week to groom and check, because they can hide rubs, weight changes, skin fungus and bacterial infections. University of Maine says to remove a long-worn blanket now and then to check for rub spots and body condition. Penn State says to take it off regularly to inspect for damage and to reposition because of twisting.

One last cause worth ruling out: heat. Practical Horseman lists a blanket that is too heavy as a cause, so if he is damp under the blanket, go lighter. Our too hot or too cold page has the check.
