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.

• Eye testing using the BVA/KC/ISDS Eye Scheme

Please visit our Health Test Results Finder to discover the DNA or screening scheme test results for any dog on The Kennel Club's Breed or Activity Register.

You can also view the inbreeding coefficient calculation for a puppy's parents, or for a dog you're thinking of breeding from.

We don’t currently offer a breed-specific DNA testing package for this breed, but we have a wide selection of individual DNA tests available. To find out more and view our full selection, click here.

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.

Health (The Kennel Club)

Have any questions about health in your breed?

If you have any concerns about a particular health condition in your breed then you may wish to speak to your vet or you could contact your breed health co-ordinator.

Breed health co-ordinators are individuals working on behalf of breed clubs and councils who are advocates for the health and welfare of their chosen breed. They acts as a spokesperson on matters of health and will collaborate with The Kennel Club on any health concerns the breed may have.

Health issues in flat-faced dogs

Dogs with a flat, wide shaped head, are said to be brachycephalic (brachy, meaning short and cephalic, meaning head). This particular skull shape will often give these dogs a characteristic flattened face and a short muzzle. Although the shape of these dogs’ heads can make them look very cute, dogs with a very flat face and short muzzle have a higher risk of developing certain health issues associated with their features. Some of these issues are outlined below, but for more information on the health and welfare of flat-faced dogs, visit our brachycephalic hub.

Breathing difficulties

The soft tissue in the nose and throat of some brachycephalic dogs may be excessive for the airways, making it difficult for them to breathe normally (causing heavy panting or noisy breathing). Some dogs may also have narrow nostrils making it even more difficult to breathe.

More information can be found on:

• our film about breathing problems in flat-faced dogs
• from the University of Cambridge website
• in our article on breathing problems in flat-faced dogs

Skin problems

Some brachycephalic dogs may have an excess of skin, which creates folds, especially around the front of the face. These folds can make a warm, moist environment which is perfect for bacteria and yeast to grow, possibly leading to infection and severe itching.

More information can be found in our article on skin problems in flat-faced dogs.

Teeth problems

Dogs with a shortened skull will often have a shortened jaw, but the number and size of teeth will stay the same. This can mean that the teeth become overcrowded and can cause dental and gum problems.

More information can be found on our advice page on how to take care of your dogs teeth.

Eye conditions

Some brachycephalic dogs may have shallow eye sockets, causing their eyes to become more prominent and at a higher risk of trauma, ulcers and increasing the chance of them becoming dry and painful (due to not being able to blink properly).

More information can be found in our article on eye problems in flat-faced dogs.

Want to buy a puppy responsibly?

Not all flat-faced dogs will have the health issues described, but it is important that if you are thinking of buying a puppy, that you take extra precautions. 

There are not currently any additional breed specific restrictions in place for this breed.
