Perhaps Lepto is prevalent in your area? That is something you really need to find out if you have not already. Maybe your vet is very concerned about your pup getting Lepto??
As for the flea preventatives, I used Advantage for years without any ill effects. I use Heartgard for heartworm prevention....a couple of my pups are on Sentinel. You could use that and it would cover heartworms and fleas.
