Health & WellbeingWhat's the best flea, deer tick, heartworm for dogs, cats, and kids?
Great question! Nexgard kills the deer tick as well as fleas and American dog tick/rocky mountain tick, and lone star tick. It is an oral pill as well, so I would us that for your dogs. Because Nexgard doesn't protect again heartworms, you will have to give your dogs Heartgard as well, which is available by prescription only from the vet. Advantix is a spot on treatment that treats the same things as Nexgard, but you would also have to use Heartgard as well for the heartworms. These two medications (Nexgard and Advantix) are for dogs only. As for the cats, Simparica prevents five types of ticks, so this may work for your cats :-)
