FRONTLINE Tri-act L 20-40 kg - antiparazitické kvapky pre psov - 3 x 4 ml

Parasites like fleas, ticks, sandflies, and mosquitoes are more than a nuisance—they can transmit serious diseases to your dog. FRONTLINE Tri-act L provides a powerful monthly spot-on treatment tailored for large dogs weighing 20–40 kg, combining three active ingredients to kill and repel a broad spectrum of parasites. Each pack contains three 4 ml pipettes, offering three months of protection.

Who is it for

This product is for owners of large breed dogs (20–40 kg) aged 8 weeks and older who need reliable, vet-strength parasite control. It is ideal for dogs that spend time outdoors, in areas with high tick or sandfly populations, or in households with multiple pets (excluding cats—see precautions).

Tips

Apply the entire contents of one pipette directly onto the skin between the shoulder blades, where your dog cannot lick it off. Part the fur to ensure the liquid reaches the skin. Do not bathe your dog for 48 hours after application. Keep treated dogs away from cats, as permethrin is highly toxic to felines. Store in a cool, dry place away from children and pets.
