Really? I’m going to have to look into that. I know I’ve always read that if at any point in time the temperature dips below 57 the cycle needs to start again. Dr. Becker’s article says: “During the time the heartworm larvae are developing from L1 to L3 inside an infected mosquito, which is approximately a two-week period, the temperature must not dip below 57°F at any point in time. If it does, the maturation cycle is halted. According to Washington State University heartworm report from 2006, full development of the larvae requires ‘the equivalent of a steady 24-hour daily temperature in excess of 64°F (18°C) for approximately one month.'” So I suppose – according to Washington State University – if the overall temperature averages over 64 for a month you’d need the preventative even if it dips below 57 at times. Well it’s only been up to the 80’s for about a week (it was snowing only three weeks couple weeks ago – north country lol) – definitely has not averaged over 64 for a month. I put my sticker on the calendar to start the first dose Thursday so I’m sure they’ll be fine either way.
