A dog swollen face can appear suddenly and look alarming, with puffy eyes, a fat lip or a lopsided muzzle. Many cases are allergic reactions that respond quickly to treatment. Others, like dental abscesses, need a vet within a day. A few are emergencies. Here is how to tell.
Go to an emergency vet right away if facial swelling comes with:
Severe allergic reactions, called anaphylaxis, can become life-threatening quickly.
See a vet the same day if:
Do not give human antihistamines or other medications without speaking to a vet first. Some products contain ingredients that are unsafe for dogs, and the right dose depends on your dog.
Treatment depends on the cause. Allergic reactions may be treated with injections. Abscesses may need antibiotics, dental X-rays and tooth extraction. Snake bites may need antivenom and hospital care.
Photos of facial swelling can help a vet judge urgency and decide whether your dog needs the ER right now. See how to take photos and videos for a telehealth vet.
Mild allergic swelling often improves within hours with treatment. Swelling from abscesses or injuries lasts until the cause is treated.
Ask a vet first. Dosing depends on your dog, and some formulas contain unsafe ingredients.
