Highland terriers are a group of dogs including the Scottish, Skye, Dandie Dinmont, and West Highland White Terriers. Gaiman later refers to Miss Spink’s and Miss Forcible’s dogs as ‘Scottie dogs’ (p27), which suggests the dogs in Coraline are specifically Scottish Terriers.
Scottish Terriers have a compact, strong body with short legs, pricked ears and a naturally erect tail. They are either black, a pale wheat like yellow or streaky coloured. They can be a little stubborn, quick tempered and energetic.
