Bee and Wasp Sting Season: What to Know

Warmer months bring significantly more bee and wasp activity, and curious dogs — who often investigate or even try to catch these insects — are more prone to getting stung during this period than the rest of the year, making late spring through summer the peak season for this specific, generally minor but occasionally serious concern.

Most stings cause a localized, mild reaction — swelling, redness, and mild pain at the sting site, generally on the face or paw given typical investigation behavior, resolving on its own within a day or so without needing veterinary intervention.

A minority of dogs experience a more significant allergic reaction, ranging from more widespread swelling and hives to, in rare but serious cases, a severe systemic allergic reaction (anaphylaxis) that can affect breathing and requires immediate emergency treatment.

Stings inside the mouth or throat carry elevated risk regardless of allergic tendency, since swelling in this location can affect the airway directly even without a full allergic reaction — a dog who snaps at a bee or wasp and gets stung inside the mouth warrants closer monitoring than a paw or facial sting.

Signs that indicate an emergency rather than a normal mild reaction include difficulty breathing, extensive swelling spreading beyond the immediate sting site, vomiting, weakness, or collapse — any of these warrant immediate veterinary attention rather than home monitoring.

For a normal, mild, localized reaction, removing a visible stinger if present (bees leave a stinger behind; wasps generally don't), applying a cold compress, and monitoring for the next hour or two is generally reasonable, though checking with a vet about an appropriate antihistamine dose for your specific dog is worth doing in advance, before you need it in the moment.

What to do: Monitor any sting for the first hour for signs of a more serious reaction, treat mouth/throat stings with extra caution regardless of how mild they initially seem, and seek immediate care for any breathing difficulty, significant spreading swelling, or systemic symptoms.
