Use a credit card to remove all stingers, Treat each swelling locally (With ice or numbing agent) and immediately seek veterinary help if showing any signs of allergy
If the dog is not allergic, Benadryl or another anti-histamine will help with the swelling and itch. If the itching is severe, grind some oatmeal real fine and give the dog an oatmeal bath. This will help with the skin irritation. If the dog is allergic, he should see a vet. He may require a prednisone injection.
Make a paste out of water and baking soda and apply to wound. If you notice hives, vomiting, seizures, trouble breathing, lethargy, severe swelling, seek emergency care ASAP
