Comfortis works really well on fleas but does not do anything for ticks, I called the company because my dog was also on Heartguard which has Ivermectin in it, company said it was ok to give as long as we were only using the lower dosage forms of Ivermectin like in the monthly heart worm preventives.
I used comfortis for a couple months last year just long enough to get rid of all the fleas we had. (first time in 20 years I had fleas on my dogs)
I don't use flea meds during the winter months.
This year we're trying out the new Nexgard instead of the topicals I used in years past.
So far seems to be working fine.
