You would assume the thought of a bunch 12 inch long worms living in your dog's heart and arteries that supply the lungs would terrify the average pet owner. Yet statistically less than half of Kokomo's pets are on a preventive product. This is a disease that can kill you dog or cat, yet costs from $10.00 – $15.00 per month to prevent. If your dog gets heartworms and we catch it early enough to treat them (yes it is treatable), it can cost $500-$1000 to treat it. In North Central Indiana we are in one of the highest incidence areas in the country. Veterinarians in Kokomo, and we at Jefferson Road Animal Hospital see several dogs a year die unnecessarily. Because it is mosquito transmitted the main contagious season is mid to late summer, but what many pet owners don't realize is that to get complete protection the preventive products must be given for at least 3 months after the last potential mosquito bite. Most years, (not reliably) that would be mid to late October, which means you must give the preventive until at least December or January. The American Heartworm Society recommends that the products be given every month of the year for a number of reasons I will expound upon in future blog.
