Some toy bull-terriers have a curved back which looks as if the dog were cringing. This peculiarity has been attributed to the fact that they have been carried under the arms or even in the pockets of their owners for generations, and that finally nature adapted the dog to its usual position. This is as it may be. Toy bull-terriers ought to have an alert, gay appearance, coupled with refinement, which requires a nice whip tail. The best colour is pure white. A brindle spot is not amiss, and even a brindle dog is admissible, but black marks are wrong. The coat ought to be loose and stiff to the touch. Toy bull-terriers are not delicate as a rule. They require warmth, and never are better than when taking plenty of exercise in all weathers.
