The Great Dane, Danish Hound, Deutsche Dogge, Boarhound, or German Mastiff is a breed of domestic dog (Canis lupus familiaris) known for its giant size and gentle personality. The breed is commonly referred to as the "Apollo of all breeds." Great Danes are considered one of the tallest dog breeds along with the Irish Wolfhound. More recently, Great Danes have been in the Guinness World Records for tallest dog. The Great Dane was named the state dog of Pennsylvania in 1965.

West Highland White Terriers, commonly known as Westies, are a breed of dog known for their distinctive white coat.[1] This breed is commonly recognised through its use as a mascot for Black & White (a brand of Scotch whisky), and on the packaging of Cesar brand dog food.

Westie Terriers have bright, deep-set eyes which tend to be dark, with a "piercing" look. Their ears are generally small, pointed, and erect.[3]

They typically weigh from 15 to 20 lbs for male dogs and 13 to 16 lbs for female dogs and their average height is 9 to 11 inches (28 cm) at the withers.[3] The Kennel Club has recommended that their tails, typically "carrot-shaped", should never be docked.[4] The tail should be between 5-6 inches.[3]

They also have deep chests, muscular limbs, a huge skull, a short and a closely fitted jaw with "scissors" bite (lower canines locked in front of upper canines, upper incisors locked over lower incisors).[5] Their teeth generally appear quite large for the size of the dog.[3][5] Westies have a very strong bone structure for their size.[5]

They have a soft, dense undercoat and a rough outer coat, about 2 inches long, that requires regular grooming.[3] Some Westies have "wheaten tippings" on their backs, though for individuals put forward for conformation showing this can be regarded as undesirable.[5]

This breed is a non-shedding dog.

Their paws are slightly webbed and thickly padded
