These drops have prevented her from getting fleas and ticks which are common from the deer, ground hogs, skunks, and squirrels. I put it on my dog once a month after a I wash her. ### ⭐⭐ mixed feelings. *by T***Y on Reviewed in the United States on August 2, 2017* arrived on time. but it has been almost two months. my dog still has fleas. so i am not thrilled with this product. i have gotten this product from my vet. and it has always worked better. ### ⭐⭐⭐⭐⭐ No more bugs *by D***A on Reviewed in the United States on November 2, 2018* No bugs on my pugs!
