We ordered Nexgard for our dog and it is working great, no fleas. The directions recommended giving the Nexgard in a way that it would be chewed, rather than swallowed whole. We knew that our dog would just swallow it, so we broke it up and mixed it with a little peanut butter, and she ate every bit of it! So easy, and 2 weeks later, no fleas! Great product, and Pet Bucket definitely has the best prices. I will place my next order when I give the last dose, shipping does take about 10 business days.
