Poor Brooklynn! I would worry that she is having an allergic reaction to something. Sometimes we are able to figure out what a dog has had an allergic reaction to and sometimes we can't. Either way, we need to resolve the allergic reaction. The only over the counter product that can be used at home is Benadryl (https://www.petcoach.co/canigive/dog/benadryl/). However, your vet can give a Benadryl injection that will work more quickly and may also give a steroid injection if needed, so I would recommend having your vet evaluate her and decide on the best treatment for her. If the bumps are getting worse, Brooklynn is not eating or she vomits, she needs medical attention. If she appears to have trouble swallowing or breathing, it is a medical emergency and she needs to be seen by a veterinarian right away. Good luck! I hope that was helpful and that Brooklynn feels better soon. Thanks for using PetCoach.
