I am sorry that we did not get to your question sooner! I hope that Mia is feeling and looking much better. It sure looks like she had an allergic reaction. We often don't know what has caused it, no matter how hard we try to figure it out! If that happens again, you can give Benadryl at home, here is an article with info including dosing information. https://www.petcoach.co/pet-medication/benadryl/ If she isn't improving within 1 hour of giving Benadryl, or if she continues to get worse, take her to a vet. Again so sorry we weren't able to help you right away this time. I hope Mia is doing better. Thank you for using PetCoach!
