My dog woke up with a really swollen leg today, my parents think it might be a sting from a hornet.

Hi, thanks for using PetCoach! Poor Honey! Her leg is very swollen and I highly recommend taking her to the Vet today. It could be an allergic reaction from an insect but it could be something more serious: lymphatic obstruction from a mass/cancer, low blood protein, vasculitis, snake bite. It is likely very uncomfortable for her. Below is a link for Benadryl but I would take her to the Vet. https://www.petcoach.co/canigive/dog/benadryl/ I wish you all the best!
