My husband was so happy today - he came home from Costco with Kirkland Flea and Tick control. It has 6 doses!! It costs 19.95. It scares me - it's twice as many doses as Frontline for half as much. I've googled it and found some information but not much. Has anyone tried it or does anyone know anything about it? I'm really afraid to try anything on my Bear - we lost our two Shelties last year and I'm so hesitant to try anything that might be harmful to this little guy. Thanks for any responses!
