Great coverage from pests for my Bella
Been using on my French Buil dog for 4 months. Works great, no skin or adverse reactions and MUCH easier on my budget than RX I used previously.

Keeps my dog and family happy.
For less than $8/mo, this keeps my German Shepard happy and itch free. He know it helps him, as well, and will sit still for me as I apply it to his back. It works fast, is plenty effective for a dog his size, and lasts the advertized 30 days. I can usually tell when it starts wearing off if I'm not keeping track because my dog starts scratching again. This also keeps fleas out of my house, as well. We only own a single dog, but as long as he's treated, there's no issues. I feel this is a safe option too when considered around small children. We just don't allow any petting for the first day after treatment. Overall, this is an excellent product at an affordable price.

Excellent product!
We live in the pine trees of the forest with 5 dogs. Best product I’ve found for a full 30 days or more of tick prevention! Not as great for fleas, lasts about 3 weeks. Still the preferred product for our hiking dogs.
