Easy treatment

[This review was collected as part of a promotion.] Now that the weather is getting warmer and we’re going on walks and exploring, my dog needed this! I’m so worried about ticks and fleas, and this treatment is perfect because you can apply on their coat. So far, no ticks or fleas on him! I love that he’s protected and happy!
