How often should you use Frontline Spray for Dogs and Cats

Understanding Frontline Spray

Frontline Spray is a popular and effective product used to protect dogs and cats from fleas, ticks, and other parasites. It contains an active ingredient called fipronil, which targets the nervous system of these pests, ultimately leading to their demise. This easy-to-use spray is applied directly onto your pet’s fur, providing long-lasting protection. However, it is crucial to understand how often to use Frontline Spray to maximize its effectiveness and keep your furry companions parasite-free.

General Recommendations

The frequency of Frontline Spray application depends on several factors, such as your pet’s age, health status, and lifestyle. In general, it is recommended to apply Frontline Spray once every 30 days. This monthly schedule ensures continuous protection and helps prevent reinfestation. However, if your pet is heavily infested with fleas or ticks, it may be necessary to apply the spray more frequently, following the guidance of your veterinarian.
