I can understand how some people may not want to give heartworm meds - but it really IS like playing Russian Roulette - with your dog! And let me give you some real life examples.
I live in Phoenix, AZ -- we don't have an especially outrageous incidence or prevalence - nonetheless -- I've always treated for heartworm EVERY SINGLE MONTH here in AZ.
I work in rescue a lot here, and pick up a lot of strays and it's just mind boggling - in this rather low-ish area of incidence/prevalence -just how many strays/rescues I've been involved with who are positive for heartworm. It is FOR SURE out there, folks. No doubt about it.
