Dogs have been man’s companion for about 35,000 years. Long enough for us to give them their own constellation sometimes before the second century, Canis Major.
This constellation includes Sirius or the dog star, the brightest star in our night sky. The ancient Roman astronomer, Claudius Ptolemy included it in his 48 constellations. In Greek myth Orion, a hunter, is followed by his dogs Canis Major and Minor. These dogs still follow Orion (most commonly identified constellation) in the sky.
