Bests & Worsts Reviews from Amazon

My dogs like these and it keeps them flea free with just one dose/day. But I have to give them year round. When I didn’t keep up the dose in the winter they picked up fleas from other figs or the grass in the spring. These flea and tick chews prevent flea and tick infestations but not instantly! And, as far as I can tell, don’t cause existing ones to die! If your dog as them, I’d advise to take them to a groomer to be bathed with flea and tick solution first.
