What are the benefits of using Effipro Spot-on?

Effipro Spot-on offers extended protection against fleas and ticks, reducing the risk of infestations and associated health concerns. Its easy application and waterproof design ensure continuous defence, even for dogs that swim or are bathed often.

How does Effipro Spot-on work?

Effipro Spot-on spreads across the dog's skin and coat, forming a protective layer against fleas and ticks. The active ingredient, fipronil, affects the nervous system of parasites on contact, efficiently eliminating them before they can bite or reproduce.

Is Effipro Spot-on safe for my dog?

Effipro Spot-on is generally safe for dogs over 2 months old and weighing more than 2kg. However, it's advisable to consult a veterinarian before beginning any new treatment, particularly if the dog has pre-existing health conditions or is pregnant or nursing.

Can I use Effipro Spot-on on my cat?

No, Effipro Spot-on for Very Large Dogs is formulated specifically for canine use. Using dog-specific flea treatments on cats can be dangerous due to differences in metabolism. Virbac provides a separate Effipro Spot-on product tailored for cats.

Are there any side effects I should be aware of?

While side effects are uncommon, some dogs might experience mild skin irritation at the application site. If unusual symptoms or behavior are noticed after using Effipro Spot-on, discontinue use and consult a veterinarian immediately.

Effipro Spot-on should be applied every 4 weeks to maintain continuous protection against fleas and ticks. If your dog swims or is bathed frequently, more frequent reapplication may be necessary.
