Frontline for dogs is an over-the-counter topical medication that contains the drug fipronil. When used monthly, Frontline treats flea infestations and prevents re-occurrences, however, the drug has the potential to cause side effects in some animals.
Types of Side Effects
The most common side effect of Frontline for dogs is oiliness of the coat around the site of application. If the dog licks itself at the site, it may drool due to the unpleasant taste of the medication.
Drug Interactions
Combining Frontline with other types of pesticides like flea or tick medications may cause harmful side effects, warn Doctors Foster and Smith.
Risks
Some pets develop allergic reactions to Frontline, causing skin irritation at the site of application, warns Merial, the makers of Frontline. This is most common when pet owners use more than the recommended dose.
Expert Insight
If your dog shows signs of irritation like redness of the skin or itching that does not improve within a few days or becomes worse within the days that follow the application of the medicine, contact your veterinarian as this may indicate an allergic reaction, explains Merial.
Considerations
Frontline for dogs is not safe for use in puppies under eight weeks of age, reports Merial. If your dog experiences an allergic reaction to Frontline, do not use the product again.
