The British Columbia black wolf (Canis lupus columbianus) coat is usually black, sometimes mixed with grey or brown. The black coat colour is a result from wolves interbreeding with dogs over 45,000 years ago. British Columbian wolves are a coastal wolf so unlike most wolves that live deep in the woods these live close to the coast in British Columbia – specifically a narrow region that includes those parts of the mainland coast and near-shore islands that are covered with temperate rainforest, which extends from Vancouver Island, British Columbia, to the Alexander Archipelago in south-east Alaska, It is one of the larger subspecies of the Grey Wolves in North America – the largest wolf ever recorded was a black wolf living in Yellowstone National Park that weighed 143 pounds.
