VIRBAC Effitix Spot-On for Dogs Large (20–40 kg)

VIRBAC Effitix Spot-On is a monthly topical solution that provides reliable protection against fleas, ticks, and biting flies in dogs. Developed by VIRBAC, a globally recognized leader in veterinary products, Effitix combines two active ingredients to deliver broad-spectrum parasite control through a simple spot-on application.

The Large variant is formulated for dogs weighing between 20 and 40 kg, making it suitable for a wide range of medium-to-large breeds. Applied directly to the skin between the shoulder blades, it spreads over the coat and skin to provide full-body protection against external parasites for up to four weeks.
