Bull Terrier (Miniature)

Although small Bull Terriers had been known in 19th century, the Miniature Bull Terrier was first recognised as a separate variety in 1943.

The miniaturisation was developed through the breeding together of smaller specimens of the Bull Terrier, the challenge for breeders being the difficulty in getting the head type, substance and soundness of dogs of smaller frame – preferably under 35.5 cms (14ins).

The Terrier breed group

Dogs originally bred and used for hunting vermin. 'Terrier' comes from the Latin word Terra, meaning earth. This hardy collection of dogs were selectively bred to be extremely brave and tough, and to pursue fox, badger, rat and otter (to name but a few) above and below ground. Dogs of terrier type have been known here since ancient times, and as early as the Middle Ages, these game breeds were portrayed by writers and painters

Other colour/s

'Other' means you consider your puppy to be a colour not currently known within the breed and one that does not appear on either the breed standard or non-breed standard list. In this instance you would be directed through our registrations process to contact a breed club and/or council to support you on identifying and correctly listing the new colour.

Non-breed-standard colours

Non-breed-standard colour means that the colour is not accepted within the breed standard and whilst some dogs within the breed may be this colour it is advised to only select a dog that fits within the breed standards for all points.

Colour is only one consideration when picking a breed or individual dog, health and temperament should always be a priority over colour.

Whether you’re thinking of buying a puppy, or breeding from your dog, it’s essential that you know what health issues may be found in your breed. To tackle these issues we advise that breeders use DNA tests, screening schemes and inbreeding coefficient calculators to help breed the healthiest dogs possible.
