My mom sent me a message today about her baby, two-year-old Maltipoo, Ace. He contracted a terrible skin bacteria infection from his Frontline Flea and Tick medicine. He takes it monthly and has never had a negative reaction until this last time. Ace had a tiny, red patch where the flea medicine was applied the day after the application. The vet told my mom it should go away but within two days, it was considerably worse. She took him in and it turns out, the area was badly infected and required antibiotics. Here are some pictures, so you get an idea what it looks like and what to look out for if your dogs take topical flea/tick medicine.
Our dogs take Comfortis, a flea/tick medicine in pill form. I fished out one of their old packages of topical K9 Advantix that states, “Individual sensitivies, while rare, may occur after using ANY pesticide product for pets.” While obviously true, my mom thought nothing of these warnings since Ace received the same medicine for months without any problems. Have your dogs ever had an adverse reaction to topical flea medicine?
Bottom line, if your dog experiences a bad reaction to flea medicine, take him or her to the vet and get it treated immediately!
