great product - would recommend

I applied last night and today morning all fleas gone. A bit surprise

quality product

I USE EFFIPRO SPOT ON DUO ON 3 LARGE DOGS, 2 WHO ARE OUTSIDE DOGS IT REALLY DOES KEEP FLEAS AND TICKS OFF THEM. I USED FRONTLINE FOR YEARS....THIS WORKS MUCH BETTER!

Effipro Duo is an easy to apply spot-on for my Bounty and it is available at such an affordable price rate that i would suggest my friends who have dogs to buy this treatment from this website only.
