Overview
A swollen face after a bite wound is often due to local inflammation, bruising, or a reaction to the injury itself. It can also happen if the wound is becoming infected or if swelling is spreading into nearby tissues, so it’s worth checking the area carefully rather than assuming it will settle on its own.
Things To Check
1. Check how quickly the swelling appeared and whether it is getting bigger.
2. Look closely for punctures, cuts, redness, heat, discharge, scabs, or a bad smell.
3. See if your dog is still eating, drinking, and acting fairly normally.
4. Check whether your dog seems sore when the face, jaw, or neck is touched.
5. Look for any difficulty opening the mouth, chewing, or swallowing.
6. Check for swelling around the eyes, lips, or under the jaw.
7. Notice whether your dog is scratching, pawing at the face, or rubbing the area.
8. If you can do so safely, make sure there is no active bleeding and that the wound is not dirty with mud or debris.
Common Causes
The most common reason is simple tissue trauma. A bite can bruise the skin and deeper tissue, which often leads to swelling within hours.
Another common cause is inflammation around puncture wounds. Even small bites can be deeper than they first look, and the swelling may seem worse than the surface injury.
Infection is another possibility, especially if the skin has been punctured or torn. Swelling, warmth, pain, and discharge can all fit with this, although not every infected wound looks obvious straight away.
Less commonly, swelling can come from a trapped pocket of fluid, a small abscess starting to form, or a reaction to something in the wound such as dirt or saliva.
What To Do
Keep your dog calm and stop rough play, running, or rubbing at the face for now.
If the skin is broken, gently keep the area clean and dry. Don’t use harsh products or try to squeeze any swelling.
Watch the swelling closely over the next few hours. If it is improving, that’s reassuring, but if it is increasing or the area looks more painful, it should be checked.
Keep an eye on eating, drinking, breathing, and comfort. Changes in any of these can help you judge whether the problem is settling or becoming more of a concern.
If the wound was caused by another dog or animal, it’s sensible to inspect for hidden punctures, especially around the face and neck where bites can be harder to see.
When To Contact A Vet
Contact your vet promptly if the swelling is spreading, your dog seems painful, the wound is deep or punctured, or you notice discharge, heat, or worsening redness. Get urgent advice if there’s trouble breathing, swallowing, opening the mouth, or if the swelling is around the eyes.
Products That May Help
