Welsh Terrier

An early name for the breed was the Welsh Black and Tan Rough Coated Terrier – and that is a very accurate description, now compressed into its present title. The broken coated black and tan terriers of the 18th century were influential behind many terrier breeds and the huntsmen of Wales stayed true to this colour, adding Irish Terrier and Airedale and later the Lakeland to reduce size and add some refinement in the development of breed type.

The breed was used on fox, otter and badger and was often used by hunts, running alongside hounds.

The first breed club was formed in 1885 in Pwllheli when the first breed show was held.

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.

Breed Standard colours

Breed standard colour means that the colour is accepted within the breed standard and is a traditional and well-known colour in this breed.

Black & Tan

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 considering buying a Welsh Terrier puppy or breeding from your dog, it's important to understand the health issues that may affect the breed and how they can be managed or avoided.

Pre-breeding Health Screening

Good Practice schemes and tests

We strongly recommend that breeders, at a minimum, conduct these tests before breeding, as evidence indicates these conditions are a significant concern in the breed.

Breed Health & Conservation Plan

The Breed Health and Conservation Plans

Our breed health and conservations plans (BHCPs) use evidence and data to help us understand the health issues found in each pedigree dog breed. These plans help breeders and owners identify health and welfare problems and use information, health tests and health schemes to avoid passing on those problems to future puppies. They also support and provide breeders with tools and specialist expertise to help manage genetic diversity, understand the impacts of close breeding, and find the best ways to preserve the population of their breed.

Working together for the breed

We’ve worked with breed clubs and breed representatives to gather all available evidence to help us determine the priority concerns for the breed and decide how we can work together to manage and reduce these problems.

The full evidence base is available at the discretion of the breed clubs, however if you would like to seek access to the full report, please contact our health team.
