At a glance
Dogs and cats often snap at wasps, which means stings frequently occur inside the mouth or on the muzzle. Cool the site gently and keep an eye on the animal. If there is swelling in the mouth or throat, breathing difficulty, heavy drooling, vomiting or signs of circulatory problems, contact a vet immediately.

It is not only people who get stung: dogs and cats frequently cross paths with wasps and bees as well, usually because they curiously snap at the insects. This article is not a substitute for veterinary advice.
Typical sting sites and signs
In dogs and cats the sting site is often on the face, the muzzle, inside the mouth or on the paws. Signs of a sting include sudden shaking of a paw, limping, licking or nibbling at one spot, visible swelling, as well as a brief yelp or restlessness. With stings on the face, the muzzle often swells noticeably.
What you can do straight away
Cool the affected area gently, for example with a cold pack wrapped in a cloth — animals do not always tolerate cold willingly, so proceed carefully. A visible bee sting can be carefully scraped out sideways with a card. Watch the animal closely over the following hours, paying particular attention to breathing, behaviour and how the swelling develops.
When to see a vet
Contact a vet immediately if:
- the sting is in the mouth or throat area
- your animal shows breathing difficulty, heavy drooling or retching
- the swelling spreads considerably or affects the eye
- vomiting, diarrhoea, severe restlessness or circulatory weakness occur
Small dogs and cats are more sensitive to the amount of venom than large dogs because of their lower body weight. If there are several stings at once, for instance after an attack on a nest, a veterinary check is especially important, even if no obvious symptoms are apparent at first.
Bee sting or wasp sting in an animal?
As in humans, only a bee sting leaves the sting and venom sac behind. You can read more about the difference between the two insects and how to remove the sting correctly in our guide “Bee sting or wasp sting?”. Basic information on what to do after a sting — which applies to animals in much the same way — can be found in the pillar guide “Wasp sting — what to do?”.
Frequently asked questions
How do I know whether my dog or cat has been stung?
Typical signs are sudden shaking of a paw, limping, licking, or swelling on the face, paw or muzzle. Some animals also seem restless or yelp briefly.
Is a sting inside the mouth particularly dangerous for animals?
Yes. As in humans, swelling in the mouth or throat can narrow the airways. If there are signs of breathing difficulty or heavy drooling, a vet should be seen without delay.
Can dogs and cats also react allergically to insect venom?
Yes, animals can develop allergic reactions too. Signs include severe swelling, breathing difficulty, vomiting or circulatory weakness. In such cases veterinary help is urgently required.
