Hi Connie; ALL the Vets in Nevada said the same thing for years every time we insisted pups from us be kept on heartworm preventative. Now they are more than aware that it is not true, and Nevada is no longer considered heartworm free. This is a traveling society.....you never know where the neighbor over the hill came from and if it were me I would keep my dogs on the heartworm meds as you don't know who is coming to the shows you are going to and what someone is seeing the Vet for or any dog passing by has ....... There was a time when heartworm was considered a "Southern problem"......and California was considered completely safe. Now in NORTHERN California it is considered the HOTBED of heartworm .......and part of the reason is because of all the wildlife infected with it. We have had many many breeders say the same thing.......until they have a dog go through the treatment..............

And you continue the meds AFTER the season is over. And yes, what I learned was that not every mosquito carry the heartworm larvae, but I didn't ever get one to answer me when I asked which one they were when they got me! Stormy WRITE THOSE LETTERS!!!
