"Yellow collars!... attack left.
Blue collars!... attack straight.
Grey collars!... attack right!
"Black collars..... No escape!" Yelled out the main commanding officer, who was currently holding a megaphone on the back of a moving truck.
.
As the commands were issued out, the dogs all 'whoofed' out at once.... as if saying: 'yes sir'.
And with that, they were off!
One should know that dogs couldn't see colors that ranged from green to red.... which included pink and so on, as they could only see the world in shades of yellow, blue, gray and black.
.
So at the start of every week, they were given colored collars.... and told what their english codenames would be, while they were on duty every night.
Something like Yellow collar or blue collar was their mission code name based on their collars.
The ordinary dogs were given the first 3 colors... but the huge boss dogs all had black collars instead.
