    How to apply:

    Remove product tube from package. Holding tube with notched end pointing up and away from the face and body, cut off the narrow end at the notches with scissors. While holding the dog with one hand use the other to apply the solution. Invert the tube, and use the narrow end to part the dog's hair while gently squeezing to apply to the dog's skin. Hold the dog for a few seconds to give the solution time to be absorbed into the dog's coat. When finished, wrap the tube in paper and put into the trash.

    For dogs weighing over 40 lbs.: Apply the entire tube (4.5 mL) (.15 fl oz) as a continuous stripe on the dog's back starting between the shoulder blades and ending directly in front of the base of the tail.

    Rated 1 out of 5 by from The smell is terrible! I treat my indoor cat because fleas can come into the house on people before settling on pets. The smell of this stuff is downright overpowering and most objectionable, and my whole house stinks now. It's affecting Neville's behavior, and the poor guy will probably stay in hiding until the odor leaves. It took two days of frequent washing to get it off my hands. I will take what's left of the package back to PetSense today to see if they'll refund my money.

    Rated 5 out of 5 by from It works! I used this on my 12lb cat and it worked great and we live in the country full of ticks and flees. Stopped using it ONLY because the smell was interfering with his ability to smell danger while outside and he was unhappy for a few days. Sorry for him but we're going back to it.

    Rated 4 out of 5 by from Love this product I have been using this product on my dogs for years, and have never had problems its rare if my dogs get a flea or trick and we live in the country. It gets used faithfully every month at the same time from end of April-October depending on weather.

    Rated 3 out of 5 by from the jury is still out I like the natural ingredients as opposed to chemicals, but our cat is white and the area of the application is gummy and yellow for some time. First application didn't get all the fleas. Same with the dog.

    Rated 5 out of 5 by from Great I have used this for the last three-years after giving my small dog a bath and works great. I was so sad when Petsmart discontinued it.
