    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.

    SENTRY Fiproguard Plus Squeeze-On for Dogs, 23-44 lbs 3 ct is rated 4.0 out of 5 by 9.
    Rated 1 out of 5 by from Switched from frontline Worst choice I have ever made. My cat who is still on frontline is 100% flea free. Unfortunately, my poor little dog is still being bitten. I have treated the lawn, the house and all pets. Still dealing with fleas. Only on the dog who was treated with this product. Now I don't know what else I can do for him. It's been less than 3 weeks since application. He's not infested but live fleas are still on him. I'm afraid to reapply early but I feel so bad for him. I even wash his bedding and sweep daily. I have 2 more tubes and I'm thinking of giving them away and buying Frontline. I had really hoped this product would work.

    Rated 5 out of 5 by from works better than the rest Every time I have used this one it has worked like indicated on the box, unlike theother brands that either don't kill the pests at all or doesn't work as long as it claims on the packaging. I have quit using the other brands and will only now use sentry or nothing.
