I used Frontline on all of the dogs 2 weeks ago and noticed last night a huge scabby area on back of my Koda's neck where the Frontline was applied. I checked the rest of her body and found nothing. I called our Vet and he had never heard/seen anything like this from Frontline but assumed it probably was an allergic reaction. I have always used Frontline on all my dogs with no issues, she is now 2, is it possible that she suddenly gained an allergy?
