Nancy. No disrespect to you or your homeopath but I believe it also depends on the area that one lives in and the prevalence of heart worms and parasites and disease in the area that one lives in that needs to be taken into account. There is no one blanket statement for what works for some will work for all. If that were the case, there would not be a need for sites like DFA and others on all things canine or feline.
