My 4-month old Aussie mix was suffering from a terrible flea infestation. We tried everything-sprays, drops, shampoos, powders, and they would all provide comfort for a few hours but then the fleas would be back! I was tired of it. A friend at work told me about the Comfortis pill, so I did some online research and was very impressed. I went the next morning and bought the pill at my local Vet's office. My puppy chewed it right up with no problems, and about an hour later the scratching had completely stopped! When I looked at her, she had dead fleas all over her. This product is amazing! I love...
