Dog Stung by a Wasp or Bee: First Aid and Vet Signs

Straight answerMost dogs stung once get a sore, swollen spot that settles. If it was a bee and the sting is visible, scrape it out sideways with a fingernail or card. Hold a cold pack wrapped in a tea towel on the area, and watch your dog closely for the next 12 to 24 hours. Never give human medicines without asking a vet first. This is general information, not veterinary advice.

Where dogs and cats get stung

Dogs investigate insects with their nose and snap at them, so most stings are on the face, muzzle, nose and inside the mouth. A sting on the nose is especially painful. Cats more often get stung on the paws and face. Cats hide pain, so watch for pawing at the face, limping or crying out.

First aid for a stung dog

Move your dog away from the area. If a nest was disturbed, more wasps will come.
Bee sting visible? Scrape it out sideways. Don't use tweezers. Wasps don't leave a sting behind.
Cool the area with an ice pack inside a tea towel, or a cloth soaked in cold water.
Watch closely for the next 12 to 24 hours. Call your vet if swelling hasn't gone down by then.
Don't give any human medicine unless a vet tells you to. Some are dangerous to dogs and especially cats.

Signs of a serious reaction

A severe allergic reaction usually starts within about 30 minutes of the sting, according to an Auckland vet dermatology practice. Signs include breathing trouble, collapse, vomiting or diarrhoea, drooling, pale gums and sudden weakness. Swelling that spreads across the head or down a leg can block the airway if it is around the face. Any of these means go to a vet straight away.

Stings in the mouth or throat

A sting on the tongue or in the throat is the most dangerous kind, because swelling can close the airway. It usually happens when a dog snaps at a wasp. Don't put your fingers into a distressed dog's mouth. Phone your vet or an emergency clinic and go.

Many stings at once

Dogs that disturb a ground nest can be stung many times, and a Hawke's Bay vet has reported dogs dying after disturbing wasp nests. Many stings can harm the body even without an allergy, and some effects show up hours later. A dog with lots of stings needs a vet straight away, even if it seems fine at first.

Keeping dogs away from wasp nests

German and common wasps usually nest underground, which is where dogs dig and sniff. Lots of wasps in one part of the garden means a nest nearby. Watch for a flight path into a hole on a warm afternoon or at dusk, and keep your dog out of that area until the nest is treated. Wasps also go for meaty pet food, so don't leave food out.

Questions people ask

How long does swelling last after a dog is stung?

Mild swelling usually settles quickly. New Zealand vet clinics suggest watching closely for 12 to 24 hours and calling the vet if the swelling hasn't settled by then, or straight away if it spreads, the face or throat swells, or your dog seems weak or has trouble breathing.

Can I give my dog an antihistamine for a wasp sting?

Only if your vet tells you to, and only what they tell you. New Zealand vets warn never to give pets human medicines without advice, because some are toxic to dogs and especially to cats. Phone your vet, describe the sting, and follow their instructions.
