Why the stinger matters for your 15 kg dog
Bee stings embed barbed stingers that keep pumping venom if squeezed during removal. A wasp’s smooth stinger lets it attack repeatedly, but each sting delivers less venom than a bee’s lodged stinger would. For a dog this size, one sting on the paw typically causes localized pain and swelling rather than systemic issues—unless they’re allergic.
Check the paw carefully: if you spot a black speck, it’s likely a bee stinger. Scrape it off sideways with a credit card edge—don’t use tweezers. Wasps won’t leave anything behind, but the area may look redder faster due to their different venom chemistry.
When swelling becomes an emergency
Monitor for swelling spreading up the leg or hives appearing on the belly within 30 minutes. A 15 kg dog can usually handle one sting’s venom load, but anaphylaxis causes sudden weakness, vomiting, or difficulty breathing—this needs immediate vet care.
Paw stings often make dogs limp and lick the area excessively. If swelling blocks blood flow (toes turn cold or purple) or lasts over 24 hours, see your vet. Otherwise, a cold compress and rest help more than antihistamines, which rarely work well for sting reactions in dogs.
Why repeated stings change the risk
While one wasp or bee sting is uncomfortable, multiple stings overwhelm even a 15 kg dog’s system. Venom from several insects can cause muscle tremors, fever, or organ damage—especially if stung on the face or mouth where swelling obstructs airways.
Dogs that snap at flying insects may get stung inside the mouth or throat. Listen for gagging or raspy breathing—these require an emergency vet even without visible swelling, as internal inflammation can escalate dangerously fast.
Long-term risks after a single sting
Most dogs recover fully within a day, but some develop heightened sensitivity to future stings. Note if your dog had excessive swelling this time—next exposure could trigger a worse reaction. No need for allergy testing unless they’ve had severe responses before.
Prevent licking the sting site, as saliva introduces bacteria to broken skin. A sock taped loosely over the paw helps. Watch for pus or heat at the site days later—secondary infections are more common than lingering venom effects.
