Always a personal choice . .. In his important book Homeopathic Care For Cats and Dogs, veterinarian Don Hamilton says of heartworm: “In dogs the “monthly” preventives are effective if given at six week intervals, and possibly even at seven- or eight week intervals….” Author/veterinarians Richard Pitcairn and Allen Schoen told us essentially the same thing when we were researching our book Scared Poopless. If you opt for this “less is more” treatment with “preventatives,” mark dosing dates on your calendar and don’t miss them.
The vets at Holistic Vet Center say: “… monthly heartworm preventatives are actually 100% effective if given every 45 days and 99% effective if given every 60 days.”
I presume that the monthly schedule was designed for the ease of remembering when to give meds. However … giving meds monthly rather than every 45 days requires more doses – and offers more opportunities for adverse reactions. For someone medicating year-round, that’s 4 fewer doses per year
