they r all great products and basically trial and error which u like
advantage washes off but it is safe enough to use every week ( certain shampoos dont wash it off)...frontline can only be used monthly but doesnt wash off. frontline spray is the cheapest but ive heard great and bad results (it is dependent on the applicator whether the person applies it correctly) i think some areas the fronline works best and others advantage works best...so go with what ur vet recommends cause thats prob the best for your area.
