Stackcol - Don’t let them pile up

Hope you have fun playing Stackcol.

Do you know how many colors dogs can see? Dogs can see blue and yellow colors, and they are really sensitive to gradient. You might wonder how guide dogs help people on roads. Traffic lights consist of three colors: green, yellow, and red. Yet, they can’t distinguish green and red, but they see the intensity of these two colors. Besides colors, guide dogs check their surroundings and make sure cars stop. Also, they hear rapid tick (audible signal) before guiding their handlers crossing the road.

Things to pay attention:

• Ask before petting them
• Don’t grab their leash
• Don’t distract them while they are on their job
• Just leave them alone while they are wearing vest (on duty)
• Provide enough walkway for both guide dogs and their handlers
