Dogs cannot see in color, so the color of the ball would not be the cause of its fear.
Dogs are normally partially color blind. They see colors, but not as good as people do.
The easiest color for dogs to see is blue.
No type of dogs can see in colour, I don't know why though.
Humans see with color. Dogs simply have less cone receptors therefore they do not see light. Dogs only see in black and white.

No

Dog's see like a color blind person would. They can only see certain colors. They DON'T see in B/W!
No, dogs see in black and white, most animals(those that hunt at night) can't see colors.
Actually, dogs see in color. They see as a human who has red-green color blindness, so they see red as green and green as red and yellow as grey. other than that, due to a study done recently, they have both rods (associated with how you see at night) and cones (associated with what you see in the day)dogs and cats both see black and white but dogs see green, red, blue, and yellow sometimes and cats see green, blue, and yellow
