If the Frontline Plus is $33.00 it's for atleast 3 treatments and i can bet hartz does not have the same ingrediants or chemicals used and the time it protects is not as long.

Also hartz does not include a med that stops the fleas from reproducing and frontline plus and some others has this in their formulas but it's your pet and your money so you have every right to chose whats in your budget but for me when it comes time to protect my lab/investment i make sure she has the protection she needs so she does not get sick or get infested with fleas or die of any tic diseases..
