My dog's face is swollen. Is it an emergency? What should I do?
A sudden swollen face is usuaally caused by some allergy, either an insect bite or an environmental allergy, or could also be a rattle snake bite.
Check for oozing little wounds, there would be a little blood oozing but not coagulating. If you find those on the head, your dog likely was bitten by a snake and needs to be seen by a vet right away.
If your dog has breathing problems, vomits or is lethargic, he should also be seen by a veterinarian right away.
If he is happy, eats and drinks, you can observe the swelling and it should go down within 24 hours. Of course you can also take him to the vet if he is not in distress. The vet will give him an exam and likely an antihistamine and/or steroid injection.
