We have a 1 year old yellow lab and she suddenly developed swollen ears this evening. This is occuring on the outside flaps of the ears with noticable redness inside. We noticed after she was shaking her head continuously. Is this an allergic reaction to something? We just brought her in two weeks ago for her annual checkup with no problems.
This could be an allergic reaction or an ear infection. Try giving your pet 25 mg of benadryl. If there is no improvment then I recommend a visit to the vet. vetcare
