Dog allergic reaction in the face

Keep the airway conversation front and center. Swelling without breathing change still needs guidance today.

Scenario	Sudden facial swelling
Vet vs poison control vs ER	Facial swelling with normal breathing may be an urgent same-day vet visit; swelling with breathing change, collapse, or vomiting is ER now. Poison control helps if a toxin or drug overdose is the suspected trigger.

Note any new food, insect sting, vaccine, or medication in the last hours
Check for difficulty breathing, retching, or spreading hives
Keep the pet calm and avoid forcing the mouth open
Call your veterinarian or ER promptly for facial or muzzle swelling
Do not give human allergy medications unless a veterinarian directs a specific dose for this pet

Look for stingers, new treats, chewed plants, or medication timing.

Remove ongoing exposure when obvious and safe.

Do not use a human EpiPen unless a veterinarian has built that plan for this pet.

Get to care for severe reactions.

This is general information, not a diagnosis. Contact your vet for anything urgent or unclear.
