Why is my horse sore or reactive when I touch a tick bite area? | arlo.® Atlas

Read time: 3 minutes

Overview

If your horse is sore or reacts when you touch a tick bite area, it’s often because the skin is irritated, a small local reaction is building, or the bite site has become a bit inflamed. Sometimes the tick has already been removed, and the area is still tender for a short time.

There can be more than one reason, so it’s worth checking the site carefully rather than assuming it’s just a simple bite.

Things To Check

1. Check whether your horse reacts only when the area is touched, or whether the soreness seems to be there all the time.

2. Look closely for redness, swelling, heat, scabbing, a small puncture mark, or any discharge.

3. Feel around the area gently to see if the sensitivity is localised or if the surrounding skin is also tender.

4. Check whether the tick is still attached, or whether any mouthparts may have been left behind.

5. Note if your horse is rubbing the area, stamping, twitching the skin, or avoiding touch more than usual.

6. Think about where the tick was found, especially under the mane, in the chest, behind the elbows, around the ears, or between the hind legs.

7. Watch for changes in behaviour, such as dullness, heat, swelling elsewhere, or a reduced willingness to be groomed or tacked up.

Common Causes

The most common cause is simple skin irritation after the tick bite. Even after the tick is removed, the skin can stay sore for a day or two.

A small local inflammatory reaction is also common. Some horses seem more sensitive than others, and the area can stay reactive even when the bite looks minor.

If the skin has been scratched, rubbed or picked at, the bite can become more inflamed and tender.

Less commonly, the site may be starting to develop a minor skin infection or there may be retained mouthparts causing ongoing irritation.

In some cases, the issue is actually a nearby lump, scab or sore that was noticed when the tick area was touched, rather than the tick bite itself.

What To Do

Keep the area clean and monitor it closely over the next day or two. If the tick is still attached, remove it carefully if you know how to do that safely, then keep an eye on the site.

Avoid rubbing, scrubbing or picking at the skin, as that can make the soreness worse. Gentle handling and basic grooming around the area are usually kinder while it settles.

Check the surrounding coat and skin for other ticks, especially after turnout or if your horse has been in long grass or brushy areas.

Make a note of any swelling, heat or discharge, and see whether the tenderness is improving. If the area is getting worse instead of better, that’s a sign to get it looked at.
