VIRBAC Effitix Spot-On for Dogs X-Large (40–60 kg)

Large and giant breed dogs require parasite treatments scaled to their body weight for full effectiveness. VIRBAC Effitix Spot-On X-Large is specifically dosed for dogs weighing 40 to 60 kg, delivering a higher-volume topical treatment that ensures adequate coverage across larger body surfaces.

Effitix combines permethrin and fipronil in a single pipette to kill and repel fleas, ticks, and biting insects on contact. The topical formulation penetrates through the coat to reach the skin and distributes across the dog's body via the skin's natural oils, providing month-long protection with a single application.

This is a practical, mess-free option for giant breed owners who want veterinarian-quality parasite control without the stress of oral administration.
