The Kennel Club have recently undertaken a Breed Population Analyses, this is taken from the KC Web Site and I have also included the link to the Field Spaniel Data as well:

Taken from the KC Website - http://www.thekennelclub.org.uk/vets-researchers/publications-statistics-and-health-results/breed-population-analyses/

Recognising the importance of managing the rate of inbreeding, the Kennel Club's Population analysis reports allow breeders to review the unique situation for each breed.

If unchecked, inbreeding levels can rise in a breed, and although its effects may not initially be noticeable, this increase can have a significant impact on the health and welfare of future generations.

The breed specific reports below provide a framework to shape discussions on the best ways to improve, or maintain, genetic health.

See the KC Link for more information - http://www.thekennelclub.org.uk/vets-researchers/publications-statistics-and-health-results/breed-population-analyses/



 The Conclusion states:- but really needs to be read in context with the above link


Comments

As can be seen from figure 1, the number of animals of this breed registered with the Kennel Club is

very small. The small population size and possible influence of migrant animals mean there may be

large fluctuations in the rate of inbreeding and effective population size. The rate of inbreeding was

at its highest in this breed in the 1980s and 1990s. This represents a ‘genetic bottleneck’, with

genetic variation lost from the population. However, since the mid-1990s the rate of inbreeding has

declined implying a slowdown in the rate of loss of genetic diversity (possibly through the use of

imported animals).

There appears to be moderate use of popular dogs as sires in this breed (the ‘tail’ of the blue

distribution in figure 3).

It should be noted that, while animals imported from overseas may appear completely unrelated,

this is not always the case. Often the pedigree available to the Kennel Club is limited in the number

of generations, hampering the ability to detect true, albeit distant, relationships.


We are at present on the BVA/KC/ISDS EYE SCHEME SCHEDULE B - CONDITIONS UNDER INVESTIGATION  BVA Register for Spaniel (Field) - HC (early developing), MRD - (information from the KC Web Site) so it is imperative that testing is continuously carried out.


See under Health Schemes Eyes for more information on these conditions

Health

The Kennel Club have informed us that the 2016 breed specific data summaries are now available on the Kennel Club website, which includes data summaries of DNA tests, the CM/SM scheme, the BVA/KC Hip Dysplasia scheme, BVA/KC Elbow Dysplasia scheme, and BVA/KC ISDS Eye scheme for 2016.

These summaries can be useful, for example, for finding out breed median scores for hip and elbow, or what percentage of the tested population are a carrier for a particular condition.

The Kennel Club have informed us that the COI (coefficient of inbreeding) breed averages have been updated.

To view the new annual breed average online, and to put this figure into context, please click here.

For Information on inbreeding and its impact on health, then information and advice is available here.


The results from the Society’s 2017 Breed Health Survey are now available here


The Kennel Club have now published a more in-depth study of the 2014 Pedigree Breed Health Survey and have provided us with our individual breed report following the survey, available here.

One aspect of the more in-depth study is looking at which breeds have shown a higher or lower prevalence for conditions than the average across all breeds. This paper is freely and publically available in the Canine Genetics and Epidemiology Journal at: https://cgejournal.biomedcentral.com/articles/10.1186/s40575-017-0047-3

The research aimed to determine the prevalence of health disorders of varying severity, influenced by both genetics and environment, among pedigree dogs overall and, where possible, determine any variation among breeds.

The results of this study will substantially contribute to the current understanding of disorder occurrence in dogs in the UK and contribute towards the evidence base for each breed’s Breed Health & Conservation Plans.
