Moved to Montana 2 years ago with our dog. Was informed by the local vet here that heart worm is not a problem here YET and I haven't used a flea repellent yet and our dog has been flea and tick free since. I do still do the monthly heartworm prevention but only as a precaution. We have a large field behind us and lots of gophers but still no fleas so it must have something to do with the weather. Unruly dogs (and people) will be shot here in Montana as everyone owns at least one gun.
We do not have much crime or home invasions as most criminals know this too

A year ago, the Boise area had over 1000 cases of heartworm diagnosed. And for every case that's diagnosed, several go uncaught (since it takes a few years for symptoms to develop). And that's what the livestock vet told me -- he probably only sees a small fraction of what's really there, since dogs aren't his major clientele.

'Rescue' has been shuffling dogs all over the country for several years now. Many are known (tested) heartworm-positive. Meaning they are effectively contagious (via mosquito bites). Because of this, a harsh winter climate no longer serves to keep heartworm out of Montana.

The rule now is "If there are ANY mosquitoes, there is heartworm."

Coyotes are a reservoir for anything that affects domestic dogs. In Texas, 100% of coyotes tested were heartworm-positive.


Fleas don't do well in a dry climate or at higher altitudes. They don't reproduce effectively above about 3500'.
