Vet Review

The non-greasy, non-odor formulation is a definite plus when used on sensitive patients, especially cats.I find that advantage kills fleas and larvae more quickly than some of the other products out there, often resulting in quicker relief of flea allergy dermatitis symptoms in dogs and cats. Overall I have found it quite safe and have seen the fewest topical or rare systemic reactions in my practice over the years. The main disadvantage I have found is that in heavy flea infestations that the efficacy may wear off in less than one month, necessitating some vets to recommend more frequent off label use of this product every few weeks. It also does not control ticks as well on dogs and cats. I find that advantage works most effectively when combined with good environmental flea control at home.
