Wolf

Wolves are powerful wild dogs that roam across North America and Eurasia. They're the biggest members of the dog family, with thick fur that can be gray, brown, black, or even snowy white in Arctic regions. These social hunters live in close-knit packs and communicate through howls.

• Wolves can interbreed with coyotes and jackals, producing fertile offspring.
• Their fur patterns blend white, gray, brown and black for camouflage.
• Arctic wolf subspecies often have nearly pure white coats.
