Canine Heartworm Disease is very common in the South and much less so
here. Many dog owners do not give a heartworm preventive because of this. All of the dogs I have treated for Heartworm Disease have come here from the South. Recently, however, a dog tested positive for Heartworm Disease that had not been to or originated from the South. Undoubtedly this dog had been close enough to a heartworm positive dog that a mosquito transmitted the disease to him. Unfortunately now the dog has to undergo the lengthy and expensive treatment for Heartworm Disease. Hopefully this situation does not become more common as many rescue dogs come into the area from the South, potentially with Heartworm Disease and dogs not on a preventive are susceptible to infection in the same way. Please keep your dog on a Heartworm preventive!
