Wondercide Flea & Tick Collar for Dogs, Peppermint - Small/Medium

Wondercide's plant-powered Flea & Tick Collar is an added layer of protection for dogs, powered by cedarwood and peppermint essential oils instead of conventional pesticides. Per Wondercide, it repels fleas and ticks for up to 4 months and mosquitoes for up to 1 month. The Small/Medium size fits dogs up to 45 pounds with a neck size between 9.5 and 21 inches. It is water resistant but not waterproof, so it should be removed before baths and swimming.
