We often hear that dogs are color blind but that is not true. Dogs see color differently than humans do. Dogs do not see the colors red and green but do see the colors blue and yellow quite well. Research has indicated that dogs may not see grey scales as vividly as humans. Also, dogs are somewhat near sighted compared to humans but can see moving objects at a distance much better than humans can. Keep this in mind when choosing your next fetch toy, a red ball on a plush green lawn will be difficult for your dog to see so choose a yellow or blue toy instead.
