Are dogs able to see in color ?

New research is dispelling the myth that dogs are only able to see the world in black and white.

Early tests in to dogs' vision seemed to suggest that their ability to discern colors was no better than that of a colorblind human and that distinguishing colors was not crucial to their everyday activities. Now however a research team in Russia lead by Anna Kasparson of the Russian Academy of Sciences has demonstrated that dogs do indeed use color as a cue to differentiate objects.

In a series of experiments colored markers were placed above a number of feedboxes. Only one of the feedboxes was unlocked, prompting the dogs to identify based on color which one it was. The results indicated that the dogs were able to identify the correct feedbox based on its color up to 70 percent of the time.

"A Russian research team has found, in a study of eight previously untrained dogs, that the animals overwhelmingly preferred using color as a cue rather than brightness."

While humans have three types of photoreceptors in their eyes that transmit signals about color to the brain, dogs have two types of photoreceptors. We know that these photoreceptors work to transmit information allowing dogs to perceive differences in color because dogs have told us so. Well, sort of. How Have Dogs Told Us That They Perceive Color? To determine whether dogs can see color, researchers taught dogs to pick the odd-colored circle out of a choice of three circles. So if they showed colors that the dogs could not distinguish, they would fail at the task, but if they chose colors th... [More]

C'mon man. Your dog prefers meat over biscuits or vegetables. It isn't the color and as far as dogs go you have no idea what smells like what to them. They can smell all the ingredients in any food and they can smell them better and separately. Okay, explain this. I found an uneaten doner kebab in the back of my car, in a beige pitta bread (inside the plastic carton).My dog went mad for it, even though the plastic carton was beige as well! Do dogs see colours we cannot?

Your question was how your dog could tell where the bowl was on a seat the same color as the bowl. The answer is your dog could smell the food in the bowl.

But that does not explain why she also likes sweet'n'sour chicken, which is also beige, apart from the red peppers. Sweet'n'sour does not smell like curry or bbq.It must be the red colouration that attracts her. Oh course she likes sween'n'sour chicken. It smells, tastes and looks an awful lot better than biscuits - would you not as well?. Colour has nothing to do with it. Even if your dog was blind she would still make the same choice. Use your common sense!

Even if your dog was blind she would still make the same choice. Use your common sense! Oh yes. I was not taking into account her sense of smell. Her usual diet of biscuits, although healthy, probably is bland, and the human diet she prefers, as well as being more colourful, contains fats and salts and spices and sugars which she probably finds as enticing as we do. So although it is not healthy, she probably thinks it is, or is at ... [More]

Dogs are also secretive. I just asked mine if she sees in color...she neither confirmed or denied it.

Somethings nature gives more, somethings less to different species. Different life species have differently focused (different) senses :-)
