The first ball which clearly visible for your dog. Everyone knows that dogs are color blind, but is that really the case? A comprehensive research at a university in America has shown that dogs can see certain colors surely. More than 4,000 clinical testing have shown that bright white and purple colors are visible for dogs. Balls with this color combination will have preference over balls with other colors. This clearly visible for dogs ball is very durable, floats in water, has excellent jumping qualities and is good for the dog to take off the ground due to the special studs, which also again clean the teeth.
