Heartworm prevention schedules

4518 Views 19 Replies 14 Participants Last post by  kafkabeetle
I know seasonal heartworm prevention relies upon typical weather, since heartworms can only survive in weather that is consistently above 55 degrees for some period of time (correct me if I am misrepresenting this). The schedule for my area is June-November. But since we've had a pretty mild winter, should I be amending this schedule in any way for the best protection? Any information or opinions on this are greatly appreciated.

I used to do seasonally too, but there has been more and more cases where I live and in areas that it wouldn't be expected, so I now do year round also.
I'm probably just get her tested soon then and start her up again right away. In your average normal year here there really are many months where there isn't much point because it's far too cold for insects, much less mosquitos actually carrying heartworms. This has definitely not been a typical year, though so I guess I'll just play it safe the best I can.

The main reason for year round is because heartworm is becoming more of a problem...Lots more cases seen year after year and a even bigger issue is the shortage on the medicine to cure it. Heartguard has a good guarantee on their medicine...if you use it year round and get the dog tested yearly and the dog still gets it(it is possible) they will pay for the vet bills associated with the heartworm.
