What is Frontline Tri-Act L Large Dogs used for?
Frontline Tri-Act Large Dogs L from Boehringer Laboratories is a 3-in-1 external anti-parasite solution for veterinary use, designed to repel, treat and prevent infestations by ticks, fleas, mosquitoes or sandflies (responsible for leishmaniasis) in medium-sized dogs (weighing between 20 and 40 kg).
This new-generation anti-parasite not only kills parasites, but also repels them, avoiding the risk of contact between the parasite and your dog. This repellent action limits the risk of disease transmission to your pet. So your dog is truly protected.
The high efficacy and broad spectrum of FrontLine Tri-Act L Spot-On 20-40 kg anti-parasite pipettes to protect your large dog is due to the unique combination of 2 molecules: Fipronyl eliminates fleas, ticks and chewing lice on your pet and protects it from reinfestation (2 months for fleas, 1 month for ticks). Permethrin is one of the most effective pyrethroids against ticks, mosquitoes and sandflies responsible for leishmaniasis. This anti-parasite is also very safe to use. And your big dog stays protected even when his coat is wet (after a bath or shampoo).
