My vet told me NOT to split the heartguard in half because the medicine isn't concentrated evenly throughout the chewable. So, even though you think you are splitting it in half, you are not actually getting half of the active ingredient, and therefore it may not be as effective.

I am curious about alternatives to Frontline. Besides adding oil to their shampoo, is there "organic" or safe, all natural flea & tick medicines? Is the oil equally as effective? We live by woods and I already found a tick on Ralfie once, but I want to put as few chemicals on (and in) him as possible.
