Title: This Advantage did NOT work!
Review: We have bought Advantage through Amazon many times, and it has always worked great. But this last batch has been completely ineffective. Might as well put water on my dogs. My dogs are small, little silky terriers, and one is horribly allergic to fleas, so we are having a terrible time. The fleas are very healthy!! We don't know what to do other than try a different company, either from Amazon or elsewhere. Sorry, Amazon, but this batch of medicine was a complete dud!!!!!
