Hi, regarding the frontline plus, i could not find the site i bought them from lasttime either, but have a phone nmbr )800 035 0746 Mon - fri 9:00-8:00pm. But googled frontline plus for dogs and found a few sites selling it, mostly in dollars, but TLC PET-PLANET sells it in pounds, they reckon 1 pippette is only meant to last a month or so, but i use it more in warm weather or when they get fleas, neither a problem at the moment, they like you to over use every thing on our animals, but i prefer to use common sense, also costs about £30.
