Back in the early 1990s Cisco's dad, Asko had his semen collected. For over 30 years it laid dormant and frozen at -300 centigrade. In August 2021 Cliff's mom Indy was surgically inseminated. Eight weeks later, a litter of pups were born. One stood out right away. He was big and very powerful looking as a pup. He excelled and finished first in every test given to the litter. He also wore a red collar, and the jingle Clifford the BIg Red Dog soon followed. The name stuck and he's been called Cliff ever since!
