<h4 class="dechead">On One Hand: Considered Safe
Frontline (fipronil) for dogs is considered a very safe product for the control of fleas, eggs and larvae, as well as ticks and lice. Frontline is a topical product, applied to the dog's skin between the shoulder blades; from there it is dispersed through the dog's skin and hair.
On the Other: Side Efects May Occur
Some dogs are sensitive to the ingredients in Frontline. The most common side effect is irritation at the application site. If the irritation continues for more than a few hours or worsens, bathe the dog and contact a veterinarian. Frontline should not be used on puppies younger than eight weeks of age or debilitated or elderly dogs.
Bottom Line
Frontline flea control is considered safe for most dogs, and side effects are typically mild and temporary. Frontline is for external use only. Owners should wash their hands with soap and water after handling. Contact a veterinarian before reapplying if the dog had a prior adverse reaction.
