Some all-white dog breeds include the Japanese spitz, Maltese, West Highland white terrier and the dogo Argentino. Other all-white breeds of dog are the Tatra Mountain sheepdog, kuvasz and Bolognese.
Like most spitz dogs, the Japanese spitz carries its tail curled over its back and has a fox-like muzzle. The coat is long and profuse. Bred to be a companion dog, the Japanese spitz stands approximately 12 to 15 inches at the shoulder and weighs between 11 and 20 pounds.
The West Highland white terrier was developed in Scotland for hunting rats. Appropriately, it has a powerful muzzle and large, strong teeth that come together in a scissors bite. Its outer coat is hard, and the undercoat is dense and softer and needs much care. The erect tail is naturally short. Like many small dogs, the terrier is long-lived and can live as long as 15 years.
The dogo Argentino is a dog bred in South America for hunting jaguars and pumas, so it's strong and fearless. It features a large head with jaws that are broad and powerful along with a short coat and no undercoat. The breed is banned in Great Britain due to concerns over dog fighting.
