i would like to know which of the flea products works the best and is the safest for my dogs and cats. i have been using the liquid drops you place between the shoulder blades but recently i have seen that there is also a pill form that is suppose to do the same thing. i often wonder about the liquid drops because they can be rubbed or licked off. is the pill or liquid more effective/safe and which brand is the best? thank you so very much.
I like advantage and frontline which is a liquid that you place on the skin. vetcare
