Can I combine Frontline and a Soresto collar on a dog? The collars weren't treating ticks but the frontline isn't treating fleas.

Yes you will not likely have any problems using both. The more baths you give the shorter the collar will work also. You might want to look into Bravecto, a 3 month pill for fleas and ticks that is working well
