Dogs are able to see some colors, but not all

Question

This claim is somewhat correct based on the New York Times article that states, "The dogs had no trouble distinguishing red and blue, the colors at the opposite end of the spectrum". The article also stated how "the dogs could not discriminate among colors from greenish-yellow through orange to red". This article explains how some breeds of dogs are different than others and that researchers found that some dogs are able to see shades of blue and red, but cannot see shades of green. This claim is somewhat misinformation because it is generally dogs as a whole and not specifying the types of colors dogs can or cannot see. This claim is backed up by the reliable source of the New York Times. 

Answer 1

It is true. According to the VCA animal hospital, human eyes have three types of cones that can identify combinations of red, blue, and green. While dogs possess only two types of cones and can only discern blue and yellow. More rods than human giving them the edge when it comes to seeing in low light or identifying moving objects.

Answer 2

     This claim is true, when I began to look up this claim, article "Do Dogs See Color" by Ryan Llera and Lynn Buzhardt state that dogs "can only discern blue and yellow." 

      Llera and Buzhardt describe it as a "limited color perception ... called dichromatic vision." The reason behind this is because human eyes have "three types of cones that can identify combinations of red, blue, and green. Dogs posses only two types of cones." Which is why they're only able to see and process only a few colors (blue and yellow).
