Why bite wounds are more dangerous than they appear
The visible skin wound is just the entry point. What happens underneath is determined by the force, direction, and teeth of the attacking animal — none of which are reflected in the size of the surface wound.
Dog bites involve tremendous crushing force. A large dog's bite can exceed 300 pounds per square inch. What looks like two small punctures on the surface may involve torn muscle, fractured bones, and damage to internal organs — particularly from bites to the chest or abdomen. The shaking behavior many dogs display during an attack generates significant additional internal damage.
Cat bites are narrow and needle-deep. They penetrate well below the surface and seal over quickly, trapping bacteria deep in the tissue. Cat bites become infected faster than almost any other type of wound — abscesses can develop within 6 to 24 hours of a bite that was not treated.
- Any bite wound to the chest or abdomen — possible internal injury
- Active, uncontrolled bleeding
- Difficulty breathing after a bite wound
- Signs of shock — pale gums, weakness, collapse
- Wounds near the eyes, face, or throat
- A cat that was attacked by a dog — even if wounds appear minor, internal injuries are common
- Any bite wound showing signs of deep tissue involvement
What to do before you arrive
- Apply gentle pressure to actively bleeding wounds with a clean cloth or gauze
- Do not probe, flush, or attempt to deeply clean the wound at home
- Do not apply hydrogen peroxide or alcohol — these damage tissue
- Keep your pet calm and still
- Muzzle your dog only if they are at risk of biting and are not having difficulty breathing

Body cavity penetration
Bites to the chest can cause pneumothorax (collapsed lung) even without a visible chest wound. Bites to the abdomen can penetrate the abdominal cavity, injuring the intestines, bladder, or other organs. A dog or cat that was bitten in the body — even if the surface wound looks minor — should be evaluated with imaging (X-rays and ultrasound) to rule out internal injuries before being sent home.
If your pet was bitten by a wild animal — particularly a bat, raccoon, skunk, fox, or coyote — rabies exposure must be considered. Inform your vet immediately. Rabies quarantine and booster vaccination protocols depend on your pet's vaccination status and local regulations. Texas has active rabies in wildlife populations.
