Why would you want to give heartworm pills daily? Also since you are a Collie fan, you have to worry about anything with Ivermectin in it, and that includes Dimmitrol.

Dimmitrol is not suitable for all breeds e.g. Collie breeds, Collie crosses and some Shepherd breeds. For Ivermectin sensitive breeds, we recommend
Sentinel Spectrum, Interceptor Spectrum, Proheart or Guardian.

Dimmitrol reference

The problem that Collies have is a genetic trait that allows more of the Ivermectin to pass through the blood/brain barrier via a cellular pump. It creates higher than usual Ivermectin concentrations in the brain leading to possible neurological problems (e.g. seizures or worse). Collies also have the same problem when dealing with Immonium A/D. It's not universal for Collies but does have a very high incidence due to the genetic mutation.

I have my N Carolina puppies on Sentinel year round, which also hits a variety of other worms. Once a month seems cheap enough.
