Wondercide Flea & Tick Collar for Dogs, Peppermint - Large

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 Large size fits dogs over 45 pounds with a neck size between 13.5 and 27.5 inches. It is water resistant but not waterproof, so it should be removed before baths and swimming.
