Description The world’s largest wild canid , the iconic grey wolf ( Canis lupus ) has been a source of both fear and respect, inspiring a rich cultural history (2) (5) . In general appearance, this species resembles a large domestic dog, but has longer legs, larger feet, a narrower chest and a straight tail (2) (3) . The fur is thick, with an outer layer composed of coarse guard hairs, below which a soft undercoat is present. The coat undergoes an annual moult in late spring, with a short summer coat growing simultaneously, which continues to develop into a winter coat in the autumn and winter (3) .
