## Description

Tell pesky parasites to ‘bug off’ with Hartz Dual Action Flea & Tick Treatment for Dogs and Puppies. Each convenient and easy to apply, single dose tube kills fleas, flea eggs, brown dog and deer ticks for 30 days, stopping the flea life cycle in its tracks. Topical formula stays on and does not rub off. Use only on dogs and puppies that weigh 61-150 pounds and are 12 weeks of age and older. Package contains three applications—a three-month supply. Directions: Remove one applicator tube from package and hold in an upright position away from your face. Pull off cap. Turn the cap around and place on top of tube. Simply press cap down to break the seal of the tube and remove cap carefully. Position the tip of the tube at the base of the pet's back between the shoulder blades and squeeze out the entire contents of the tube to form a stripe as you move from the shoulder blades along the back to the base of the tail. The treated area may appear oily after application. Repeat every month. Consult a veterinarian before using this product on debilitated, aged or medicated pets. If signs of sensitivity occur, bathe your pet with mild soap and rinse with large amount of water. If signs continue, consult a veterinarian immediately.

Review: Haven’t seen any fleas/ticks - I live in a wooded area. This actually works for our mini labradoodle. We make sure that we put it on him the same time every month.
Review: We NEVER have fleas. Ever. - I’ve used this on all my dogs for about 10 years now. Every dog responds to it the same and we never have fleas, ever! My dogs don’t itch until just about when I need to reapply. That being said when I brought in a new flea bag riddled with ticks and fleas, it took about a month to rid both dogs of them using this and shampoo because they were everywhere in the house! We literally have not had fleas in our home for about 8 years and it’s amazing! Btw we lived in FL then SC and now NC if y’all are worried about the climate.

### ⭐⭐⭐⭐ Affective on our short haired dog
*by P***T on July 23, 2024*

We use this on our short haired dog as it penetrates well and soaks the skin. It might not be as affective on our long haired dog but we have never tried it. The only draw back is our short haired dog has a greasy streak down the back for a couple of days but she is free of fleas.
