Heartworm prevention schedules

4512 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.

Most people follow a year-round preventative schedule

Unless you are an entomologist, it's too difficult to figure out just when mosquitose will be active. It only takes a couple of warm days for the eggs to hatch and the larvae to mature. Going by the calendar is unreliable.

In addition to the preventative, don't forget your yearly heartworm test.
