But, I can't find anything online that discusses treating dogs
with it to prevent heartworm and other parasites.

Probably because no one has shown it (EIS) to be effective in preventing/killing adult or juvenile heartworm.

Preventing carrying mosquitoes from infecting your dog w/ heartworm, I don't believe can be achieved using a silver solution.
