Overview
If your dog’s bite wound is red and hot, it’s usually a sign the area is inflamed and may need closer attention. Bite wounds can look small on the surface but have hidden damage underneath, so it’s sensible to keep a close eye on it and avoid assuming it’s just a minor scrape.
There can be several possible causes, including local irritation, trapped bacteria, swelling around the wound, or a deeper injury than first appears.
Things To Check
1. Check whether the redness or heat is spreading beyond the bite area.
2. Look for swelling, discharge, a bad smell, bleeding, or any skin that has opened up.
3. See if your dog is licking, chewing, guarding the area, or seems sore when touched.
4. Check whether your dog is eating, drinking and behaving normally.
5. Think about when the wound first appeared and whether it has become more red or hot over time.
6. Look for signs of a puncture, bite marks, or hair that may be hiding the true size of the wound.
7. Check for feverish behaviour such as tiredness, shivering, or not wanting to move around as usual.
Common Causes
The most common reason is inflammation after the skin has been broken. A bite can also leave a small puncture on the surface while causing deeper bruising or tissue damage underneath.
Redness and heat can also happen if bacteria have entered the wound, if there is trapped debris, or if your dog has been licking it and making it more irritated. Less commonly, the bite may have caused a deeper infection or an abscess that needs veterinary attention.
What To Do
Keep your dog from licking or scratching the wound if you can, and avoid using harsh products or home remedies on it. If the skin is only mildly affected, gently keep the area clean and dry, and monitor it closely for any change in size, heat, smell or discharge.
It’s also helpful to rest your dog and limit rough play until you know the area is settling. If the wound is on a busy area such as a leg or face, or if it seems more painful than you’d expect, it’s sensible to have it checked by a vet.
When To Contact A Vet
Contact your vet promptly if the wound is getting more red, hot or swollen, if there is discharge or a smell, if your dog seems painful, or if the bite was from another animal and you’re not sure how deep it is.
Get urgent advice if your dog seems unwell, the area is rapidly worsening, or the wound is near the eye, neck, chest, or another sensitive area.
