Canis lupus, aka the grey wolf, is a canine that is known to stay loyal to their partners once committed. These couples are also termed as “power couples,” defending their pack and each other against threats. The alphas, dominant wolves (male and female), usually mate for life, raising their cubs together and teaching them survival skills. Another interesting fact, wolves show their grief once a mate dies, and, likely, they may never make another partner until they die.
