I am more of a holistic veterinarian, although I do believe that heart worm medications are essential. I would start your dog on a canine probiotic such as Fortiflora 3-5 days in advance of the medication, and use for 3-5 days after as well. This should help. A chinese herbal called Coptis would also be beneficial.
