Revolution I use Revolution on my two boys, have since the beginning and never seen a flea or mite. Revolution protects against fleas, ticks, mites, including those that cause sarcoptic mange and HEARTWORM. My vet specializes in yorkies and he recommends it over 2 pounds and/or 12 weeks. Live in SOCAL, fleas are usually awful during the summer, boys go outside numerous times a day, never, never a flea anywhere. |
