Keeps fleas away. ### ⭐⭐⭐⭐⭐ Works on ticks *by on Reviewed in the United States June 25, 2026* Works well terrible amount of wood ticks this year. Didn’t find them crawling anymore, but they were dead after. Will be buying this product again. ### ⭐⭐⭐⭐⭐ Worth it!! *by on Reviewed in the United States June 20, 2026* Love this! No more bites, keeps all the bugs off my dog, no side effects found, no hair loss , bit pricey but worth it, cut open in a rounded shape so you don’t scratch dog when applying, cut, squeeze and done. Wrote date on box. Will continue to buy for start of spring to first snow. I put on back between shoulder blades and on top between hips just above tail so he can lick at it.
