Elive Tennis Balls High Definition Color 3 pk - Medium

Dog and human color vision is not created equal. Unlike humans, who have three color sensitive cone cells in their retinas (trichromatic), dogs have only two (dichromatic). Elive's High-Def dog toys are colored with the maximum recognizable color pigments for a dog's vision. This allows a dog to see it in a high color contrast that assures the highest visibility against any background.
