I have been using this product on my bluenose pitbull for almost 4 years now and it has never let me down. He has very sensitive skin and it doesn't bother him at all. We have never had a flea problem since using Advantage. Plus Jeffers has the best prices!
NEVER DISAPPOINTED. I HAVE 3 BIG DOGS. THEY ARE INDOOR/OUTDOOR. WE LIVE IN A RESIDENTIAL AREA IN FL. THE PROBLEM IS THAT IF ONE YARD GETS INFESTED YOU CAN BET ALL YARDS WILL BE INFESTED. THIS PRODUCT HAS NEVER LET ME DOWN.
