Is Frontline toxic to dogs?

Substances that are toxic to fleas and ticks can also be harmful to pets when consumed or applied in large quantities. While they are all highly effective, they can cause toxicity if given incorrectly or if an overdose occurs. These preventions are generally safe to use if the appropriate dose is administered. Dogs can also become exposed at toxic quantities through the ingestion or absorption of household insect sprays, foggers, and granules. Dogs often become poisoned unintentionally either through the misuse of flea and tick prevention or through the accidental ingestion or absorption of insecticides. Not all products may result in toxic symptoms as products contain varying concentrations of drug but be sure to consult your veterinarian immediately if noted. Treatment includes quick removal of the product by bathing your dog with a liquid dish soap to get the greasy substance off and rinsing the mouth with copious amounts of water. To prevent accidental exposure, follow all directions on flea and tick preventives and insecticides very carefully. Ensure that your dog only receives his prescribed medication as flea and tick preventatives are dosed on body weight.

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.
