I always check with the Vet when in doubt.We live in Fl. where the fleas are a year round prob. I have spent thousands on flea control. I had the yard treated, ripped up carpet and replaced it with tile and used Advantage and Frontline. Then my Vet rec. Comfortis. With in a week No More Fleas ! (But my Vet says I can not use it on my breeding dogs it may affect fertility or puppies and cause birth defects) So I only use it on nonbreeding dogs. No ill affects here. I use cedar chip pillows for their beds, I think this helps too. |
