Overview
A sarcoid that’s bleeding or oozing can do this for several reasons, and it doesn’t always mean something dramatic is happening. It may be irritated, rubbed, bumped, partially scabbed over, or affected by moisture and flies. Because sarcoids can change over time, it’s worth keeping a close eye on it rather than assuming it’s just a minor scrape.
Things To Check
1. Check whether the bleeding or ooze started after turnout, grooming, rugging, tack, or a knock against fencing or stable fittings.
2. Look closely at the area for redness, swelling, heat, broken skin, scabbing, crusting or a foul smell.
3. See whether the sarcoid seems to be rubbing on anything, especially rugs, tack, boots, stable doors or dense winter coat.
4. Notice if flies, wet weather, mud or sweat seem to make it worse.
5. Check whether the horse is bothered by it, such as stamping, swishing, flinching, biting at the area or resisting touch.
6. Watch for any change in size, shape or texture compared with how it usually looks.
7. Make a note of how much discharge there is and whether it’s clear, blood-stained or thicker and cloudy.
Common Causes
The most common reason is irritation from rubbing, scratching or a minor knock, which can make the surface bleed or weep.
Sometimes a sarcoid that has become fragile or crusted can ooze a little when the scab lifts or when the skin is disturbed.
Moisture, sweat and flies can also make the area sore and keep it from settling, especially in warmer months or on hard-to-keep-clean sites.
Less commonly, discharge can happen if there’s secondary infection or if the sarcoid has changed and needs reassessment.
What To Do
Keep the area clean, dry and as undisturbed as you reasonably can. Avoid picking scabs or scrubbing the site, and be gentle when grooming nearby.
If the sarcoid is in a place that rubs, think about whether rugs, tack, boots or turnout arrangements could be making it worse.
Keep a simple note of any changes in size, colour, bleeding or discharge so you can tell if it’s settling or getting worse.
If flies are part of the problem, try to reduce exposure as part of your normal summer management.
When To Contact A Vet
Speak to your vet if the sarcoid is bleeding repeatedly, the discharge is increasing, the area looks infected, or it seems to be growing or changing quickly. You should also get advice if the horse seems painful, the lesion is in a tricky spot, or you’re unsure whether you’re dealing with a sarcoid or a different skin problem.
