Frontline Plus is a medicinal pesticide which in some animals can cause some side effects or irritations.

While such occurrances are rare, it can happen. Some pets experience irritation at the application spot resulting in small irritated bumps on the skin, which animals attempt to scratch. In extremely rare cases the animals may scratch enough to cause bleeding and hair loss if left untreated.

As with any product used on your pet, observe them following applying the Frontline Plus and if they start to show signs of an irritation or any other symptoms, take them into the veterinarians office to be examined.
