Frontline Plus for dogs is generally safe to use and causes few side effects. Mild skin irritation may occur but should clear up quickly. Additional side effects may include vomiting, diarrhea, and seizure. However, these side effects are extremely rare and tend to affect smaller dogs. If you notice any adverse reactions after applying, consult your vet before applying the next dose. Some pets are allergic to fipronil, one of the active ingredients in Frontline Plus. Contact your veterinarian immediately if your dog licks the medicine, although serious side effects are rare, ingestion of any poison can cause adverse symptoms.
