Insect Stings in Dogs — Emergency First Aid (Bees & Wasps)

What to do if your dog is stung: remove the stinger, apply cold, give appropriate Benadryl dose, and recognize anaphylaxis signs. When to seek immediate veterinary care.

IMMEDIATE ACTIONS

Emergency numbers (keep them handy):

• ASPCA Poison Control: (888) 426-4435
• Pet Poison Helpline: (855) 764-7661

Check for these life-threatening or rapidly progressive signs—if any are present, treat this as an emergency and seek veterinary care immediately:

• Difficulty breathing, coughing, gurgling or noisy breathing
• Collapse, weakness, collapse/unresponsiveness
• Swelling of face, throat, muzzle or neck that could block the airway
• Pale or blue-tinged gums (poor oxygenation) or very rapid heart rate
• Repeated vomiting or diarrhea, especially if it is bloody
• Severe or rapidly spreading swelling, widespread hives (urticaria)

Step-by-step first aid procedure (for owners)

Important: These steps are for immediate first aid only. You should still contact your veterinarian—some reactions progress later and bystanders cannot reliably predict severity.

What NOT to Do (common dangerous mistakes)

• Do NOT try to suck out venom. This is ineffective and increases infection risk.
• Do NOT squeeze or pinch the stinger/venom sac—this can push more venom into the tissues.
• Do NOT give human medications like acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) — these are toxic to dogs.
• Do NOT give oral steroid medications at home unless explicitly directed by your veterinarian.
• Do NOT apply heat to the sting—heat can worsen pain and swelling. Use cold compresses only.
• Do NOT rely on home remedies (essential oils, alcohol, hydrogen peroxide) as substitutes for veterinary assessment—some can irritate the skin.
• Do NOT delay getting help if you suspect anaphylaxis simply because the dog seems mostly okay at first—severe reactions can progress rapidly.

Go to the nearest emergency clinic now or call your vet immediately if your dog has any of the following:

• Difficulty breathing, wheezing, coughing or noisy breathing
• Sudden collapse, extreme weakness, fainting
• Significant swelling of the face, neck, or mouth (risk of airway obstruction)
• Blue, purple or very pale gums
• Repeated vomiting, severe diarrhea, or signs of shock (weak pulse, cold extremities)
• Multiple stings (especially >10–20 depending on size of dog) or stings near the mouth/throat
• Signs of severe pain, inability to move, or severe lameness after a sting near a limb
• Any progression of symptoms after initial first aid

At the clinic, veterinarians can provide: oxygen, IV fluids, injectable epinephrine for anaphylaxis, injectable antihistamines and steroids, pain relief, wound care, and monitoring for complications. Dogs with severe reactions may need hospitalization and supportive care. Owners should never assume emergency treatment is optional—many life-saving interventions require professional care.

Prevention (reduce the risk of stings)

• Supervise dogs outdoors in areas with flowers, fruit trees, or known hives.
• Avoid letting dogs investigate rotting wood, deck eaves, or holes in the ground where wasps and bees nest.
• Keep outdoor trash covered and remove fallen fruit promptly.
• Teach dogs to avoid insect-rich areas; consider training recall to move them away from swarms quickly.
• Check toys and outdoor furniture for nests during spring and summer.
• If your dog has had a previous severe reaction, talk to your veterinarian about an emergency action plan. Some dogs may benefit from keeping emergency antihistamine tablets on hand (vet-prescribed) and expedited access to injectable epinephrine at the clinic.

• Remove a visible stinger by scraping (credit card) and apply a cold compress.
• Diphenhydramine (Benadryl) is commonly used at ~1 mg/kg orally every 8–12 hours, but call your vet or poison control before giving medications.
• Watch closely for anaphylaxis: difficulty breathing, collapse, facial/throat swelling, repeated vomiting or diarrhea — these are emergencies.
• Never rely solely on home treatment—veterinary assessment is important, especially for multiple stings, oral/throat stings, or severe signs.
• Keep emergency numbers handy: ASPCA Poison Control (888) 426-4435 and Pet Poison Helpline (855) 764-7661.
