About this breed
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.
Health
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.
- Prioritising genetic diversity

The breeding for health framework
Throughout 2025 we ran a major review of our pedigree dog health work, from which we have developed a new model called the breeding for health framework.
This framework covers all aspects of health and welfare that should influence breeding decisions for any breed or type of dog, building on from our previous Breed Health and Conservation Plans, and is broken down into three main areas of health:
- inbreeding/ genetic diversity
- conformation
- breed-related disease/ wellbeing
By applying the breeding for health framework, we can group all the breeds that share a certain issue together, so that we can provide targeted support and breed communities can share relevant experiences and expertise. All previous actions and priorities from the Breed Health and Conservation Plans are being transitioned into the new framework.
You can read more about the breeding for health framework here, and watch this space as we update and progress this framework to apply to your breed
