In Mesopotamian mythology, the constellation associated with "raging hounds" is Sirius, also known as the Dog Star.
The Babylonians and other ancient cultures believed that the appearance of Sirius in the sky heralded the approach of the hot and dry summer months, and they associated the star with heat and drought.
In Babylonian astrology, Sirius was also believed to be associated with the goddess Ishtar and was thought to have an influence on matters related to love and fertility.
