The compass with the star represents the north star, which was the point of origin to guide people on directions. People on land and the ocean used the north star to guide them on the right direction. The symbolism behind a compass rose has an important meaning: compasses stop us from becoming lost and help us find our right direction.
This could be taken on a philosophical level or literally. A person feeling lost in sense of direction or purpose can use the compass image as a means of gaining a particular direction and fulfilling a noble purpose.
It can be easy in dog training for us to lose our original direction of why we started it in the first place. Keeping a compass rose close to our hearts will help keep us on the dog training path we intended when we started our journey with our dogs.
