You guys know that I try to keep unnecessary meds/shots under control. So when it was time to buy more heartworm medicine, I realized it’d been a couple of years since I’d researched the latest findings. I decided it was time to dig back in to find the current “facts”. Following is a map of heartworm incidence by state. Read on below to see my current protocol.
While the above numbers are—by my book—pretty low, perhaps the rabid pushing for monthly dosing of HeartGuard year-round and other like medicines needs to be rethought. Especially since it takes 90 days for the microfilaria (baby heartworms) to grow to a larval stage; and even longer to grow into adult heartworms. If a dog is dosed with Ivermectin at any time during that 3-month larval period before adult heartworms are present, it will kill them.
Since I’m always looking for a happy medium, and I’d rather be safe than sorry, I’ve opted to dose every10 weeks for the duration of months with nightly temps over 55 degrees. I use Ivermectin Sheep Drench which I buy on Amazon. If you decide to go that route, read the first review for the correct dosing chart.
To meet my dogs’ weight requirements, here’s where we fall:
* 15 to 29 pounds: 0.1 cc
* 30 to 58 pounds: 0.2 cc
Here’s the side-by-side cost break-out comparison for 2 dogs:

$28 for 2 year supply VS $370 for Heartguard $342!
The most concise article I came across (that I then cross-checked for facts) was the The Billion Dollar Heartworm Scam.[/expand]
