Dogs and horses are colored blind
Improved Answer:
Actually, dogs can see some colour! They can pick up yellow and blue-purple colours as they have two cone types which allows them to see in limited colour. Horses also can see in blue and yellow as well. There are only a few animals that cannot see in any colour at all: Seals, sea lions, walrus' and animals from the Cetaceafamily (whales, dolphins and porpoises) have only one cone type (which is called being Monochromatic).
Dogs are 1 kind of animal that are colorblind, But that lack of color in their eyes is replaced by very keen senses of smell and hearing. Did you know that a dogs sense of smell is more than 10 times that of our sense of smell?! Dogs are not totaly colorblind. See book "Merle's Door" by Ted Kerasote. Great true story and he goes into sight and other senses of dogs.Ted does lots of writing for National Geographic and other outdoor magazines. Dogs are not color blind, they see color in a range unlike humans.

How are animals color blind?
That depends on exactly how you define the term.Humans are trichromats: our eyes contain color receptors that are sensitive to three different spectral bands.In "color blind" people, there's something wrong with one or more of these types of color receptors.Most mammals are thought to have only two types of color receptors. This doesn't make them completely insensitive to color, but it does give them a type of color blindness.Sea mammals appear to only have one type of color receptor, meaning they can only distinguish between colors based on their brightness.
