    Applying SENTRY Fiproguard products at home is easy. Just follow these steps each time you use the products.

    Before You Apply

    Applying correctly starts with purchasing correctly at the store. Before purchasing, weigh your dog. Don't guess! It is important to know the exact weight of the pet to ensure you purchase the right product.

    At the store, be sure to buy the product for the right species. BE SURE to choose cat products for cats and dog products for dogs. These products are different formulations based on the species and weight of your pet and SHOULD NEVER be used interchangeably.

    Do NOT treat with more than one pesticide product at a time. Don't forget to consider your dog's age. ONLY use SENTRY Fiproguard on dogs over 8 weeks of age.

    Always be sure to look at the label before applying.

    Applying the Product

    • Remove product tubes from the package.
    • Separate one tube from the others.
    • Hold the tube with notched end pointing up and away from the face and body. Use scissors to cut off the narrow end at the notches along the line.
    • Invert tube over dog and use open end to part your dog’s hair.
    • Squeeze tube firmly to apply all of the solution to the dog’s skin as a spot to the dog’s back between the shoulder blades.

    Rated 1 out of 5 by from Dont waist your money! I bought this a little over a month ago and my dog is still infested with fleas. I bought the Sentry Fiproguard plus for dogs 89lbs-132lbs. I bought it at tractor farm n fleet. My poor dog still whines about the fleas eating him. I thought since this stuff was so expensive it would work but of course it didnt. Im afraid to spend more money and it not work.

    Rated 1 out of 5 by from Doesn't work. Treated both my dog and cat for fleas using all appropriate guidelines... Weight, application process, etc. Two weeks later, the fleas are twice as bad! We have a clean home, all wood floors, I've laundered and treated bedding, sheets, blankets, etc. multiple times!
