Overview
If your horse’s wound smells bad and is healing slowly, check the wound closely rather than assuming it’s just part of normal healing. A smell can sometimes happen when there’s trapped moisture, discharge, dead tissue or contamination, and slow healing may suggest the area needs cleaner conditions or more careful monitoring. There may be several possible causes, so focus on what you can see, smell and compare from day to day.
Things To Check
1. Check whether the smell is coming from the wound itself or from dirty bedding, mud, sweat or discharge around it.
2. Look for redness, swelling, heat, pain, thick discharge, scabbing that keeps breaking down, or tissue that looks wet and unhealthy.
3. Note whether the wound is in a place that gets rubbed by tack, bandages, mud, flies or turnout gear.
4. Check if the wound is being kept too wet, or if it is being allowed to dry out and crack repeatedly.
5. Think about whether the horse is licking, rubbing, stamping, standing in mud, or getting the area dirty after grooming or turnout.
6. Check whether there is any increase in lameness, stiffness, swelling higher up the leg, or a change in how your horse is moving.
7. Compare the wound now with yesterday. If it is getting smellier, wetter, more swollen or more painful, that is useful information to note.
Common Causes
The most common reasons are dirt, moisture and contamination around the wound, especially if it is on a lower leg or in a muddy environment. Slow healing can also happen if the area keeps getting rubbed, picked at or reopened.
In some cases, there may be dead tissue, a pocket of infection, foreign material in the wound, or a wound that is simply healing more slowly because of its location or depth. Less commonly, poor circulation or an underlying health issue can make healing harder.
What To Do
Keep the wound as clean as you reasonably can and remove obvious dirt from the surrounding area without rough scrubbing. If the horse is in a muddy or dirty paddock, try to reduce exposure while you monitor it.
Check the wound at the same time each day so you can spot changes in smell, size, drainage and swelling. Keep notes or photos if that helps you compare progress.
Make sure any bandaging or covering is clean, dry and not rubbing. If the wound is on a lower limb, avoid letting it stay damp for long periods, as that can make healing more difficult.
If the area seems to worsen instead of improve, or if you are unsure whether the smell is coming from the wound or the surrounding tissue, it is sensible to get it checked.
When To Contact A Vet
Contact your vet if the wound smells bad and is not clearly improving, especially if there is increasing swelling, heat, pain, discharge or lameness. A foul smell can sometimes suggest tissue breakdown or infection, and wounds that are slow to heal may need a closer look.
It’s also worth getting advice sooner if the wound is deep, near a joint or tendon, or if you think there may be something left inside it.
