Ok in case your interested, I just started researching this and there is concern that some pets have been getting heartworm while taking revolution. You might want to research it if you havnt. again I have only just started. At the link below a person stated taht they love it, but thier vet has been urging them to switch because he ( the vet) has seen a few cases of dogs getting heartworm despite being on the revolution.
