Why is my dog’s cut warm to the touch?

Overview
If your dog’s cut feels warm, it can be a normal part of the early healing process, especially if the wound is small and your dog otherwise seems comfortable. That said, warmth can also happen if the area is getting irritated, inflamed or starting to become infected, so it’s worth checking the wound closely rather than ignoring it.
Most minor cuts and grazes should look calmer over a few days, not progressively redder, puffier or more painful.
Things To Check
1. Check whether the warmth is mild and localised, or whether the skin around the cut is getting hotter, swollen or more tender.
2. Look for redness that is spreading, discharge, bleeding, a bad smell, or a wet, sticky surface.
3. See whether your dog is licking, chewing or scratching at the area more than usual.
4. Check if the cut is near a joint, paw, face, eye, tail base or another area that’s likely to get rubbed or dirtied.
5. Notice whether your dog is still bright, eating normally and moving comfortably, or whether they seem dull or sore.
6. Think about what happened before you noticed it, such as a walk, rough play, grooming or time outdoors.
7. Watch for any change over the next 12 to 24 hours, because a wound that’s healing should usually look the same or gradually improve.
Common Causes
The most common reason is simple inflammation from the body healing the skin. A fresh cut can feel slightly warm for a short time, even when things are going normally.
Warmth can also come from rubbing, licking or dirt getting into the wound, which can make the area more irritated than it first looked.
If the cut is becoming more red, swollen, painful or damp, infection is another possibility. That doesn’t mean it definitely is infected, but it does mean the wound needs closer attention.
Less commonly, a small puncture, bite or hidden splinter can look minor on the surface while the skin underneath becomes more inflamed.
What To Do
Keep the area clean and dry, and prevent your dog from licking it. If they’re bothered by the wound, use a suitable collar or other vet-advised barrier so they can’t keep irritating it.
For a very small superficial cut, gently rinse away visible dirt with clean water or a saline-style wash if you already have one suitable for pets. Pat it dry carefully afterwards.
Keep an eye on it at least twice a day. You’re looking for improvement, or at least no worsening redness, heat, swelling or discharge.
Try to keep exercise calm if the cut is in a spot that could reopen with running, jumping or rough play.
If the wound starts looking more inflamed rather than less, or your dog seems uncomfortable, it’s sensible to get it checked.
