For your bigger yorkie- use Comfortis. It's wonderful about killing fleas and keeping them away. It is recommended for dogs with flea allergies and skin issues. It works great. It's the only thing that helps my Lily from being an itchy, bloody mess.
For your little one, Advantage II is cleared for use on puppies so you should be able to use it for her.
IME, the Comfortis last 6 weeks or longer. It's supposed to be given every 30 days but I hold off until I see they have a flea again. I've never had to give it closer than 5.5 weeks from the last dose and usually much longer. When my Westie was 11 pounds, we gave her the under 10 pound dosage (per our vet). |
