I pay about that maybe little less at the vets office, during this first year with Reilly I have had more problems with flea treatments, it seems his chemistry and them are not getting along to well, we keep having to change which one we use, but I would take him in every month to get weighed and I am still waiting to get the 3 pk or 6 pk until we find one that will work on both fleas and ticks like it is supposed to.
