    3. Research articles
    4. Breed club surveys

    Breed Standards: 

    There are numerous breed standards.

    The basis of breed/conformation shows is the judging of pedigree dogs against the 'Breed Standard', which is a picture in words that describes the range of features that are deemed appropriate for the breed.

    Three of the major international standards are:

    The American Kennel Club

    The Kennel Club, UK

    FCI (Federation Cynologique Internationale)

    Breed-Specific Statistics: 

    1. Swedish Insurance Data

    • Breed-specific information on rates of disease and death from Agria Pet Insurance (Agria Djurförsäkring) is available for many breeds.
    This breed has information on Veterinary Care and Life Insurance.
         This interactive tool allows for selection of disease prevalence by overall or system - below see sample image of search for partial listing of 'overall'.

    "The 2013 Cavalier Health Survey: We received a total of 5559 returns, 326 by paper and 5233 electronically via the Internet, from 38 different countries. The returns were divided into four regions and individual reports have been produced for each region:

    • United Kingdom – England, Scotland, Wales and Northern Ireland – 2927 returns.
    • FCI Countries – those countries that are either Full or Associate Members of The Fédération Cynologique Internationale (FCI). The single return from an owner resident in the United Arabs Emirates was also included in this section – 450 returns.
    • United States of America and Canada – 1883 returns.
    • Australia and New Zealand – 299 returns."

    Figure 5. Diagram of the bones referred in text (lower jaw not illustrated) with arrows to indicate anatomical changes in dogs with CM. The green colored bones are endochondral in origin (neurocranium of skull and notochord in axial skeleton). Calvaria and facial bones have membranous ossification (viscerocranium). Sclerotomal occipital region bones (i.e., craniocervical junction) indicated by red border. Purple line indicates the skull base. In dog and man, interparietal and supraoccipital fuse (yellow arrow). The reduced volume of the caudal fossa in CM is indicated by the blue arrows: reduction of the supraoccipital and dorsal displacement of atlas and axis; premature closure of synchondroses of bones in skull base (blue*) shortening the skull base and compensatory increase in height of the parietal bone and frontal bone (red arrows).



    The phenotypes of brachycephaly have considerable variation between dog breeds and consequently Brachycephalic obstructive airway syndrome (BOAS) also has variation between individual breeds and presents with different phenotypes and severity, for example, nostril obstruction in Pugs, French Bulldogs and Bulldogs (80). In these respects CM/SM can be considered comparable to BOAS i.e., a Brachycephalic obstructive CSF channel syndrome (BOCCS). Similarly to BOAS and the airway, BOCCS can be considered any distortion of the skull and/or craniocervical junction that compromises the neural parenchyma and CSF circulation causing pain and/or SM with variation between breeds and individuals.


    Conclusion and Future Developments

    This review reflects the key morphogenetic processes involved in CM/SM and how they relate to the most recent research findings for these conditions with respect to brachycephaly, craniocervical junction abnormalities and diagnosis but highlighting the need for further investigation.

    Understanding the developmental origins of complex three dimensional structures of the brain, skull, craniocervical junction and spinal cord with associated ventricles and CSF channels, is crucial to understanding canine CM and ultimately the pathogenesis of SM. The molecular genetics that underlay CM/SM can provide a powerful tool to elucidate such an understanding. However, the challenge is finding appropriate genetic markers that can achieve this, which is confounded by not having readily quantifiable pathogenic phenotypic features to study. The importance of accurate phenotyping has been fundamental for genetic studies of CM, but it is also the key for accurate diagnosis (14, 15). The complexity of the existing morphometrics involved in the current phenotypes make them impractical for everyday use and a machine learning technique for diagnosis that removes human bias has been suggested (150). Pilot studies in this technology has identified biomarkers in structures such as the soft palate not previously associated with these conditions that when investigated may give further insight into conformation change. Mathematical modeling has also been applied to the dynamics associated with CSF flow which might be used to predict the outcome following different surgical approaches (151). The challenge of quantifying and interpreting intermittent and variable clinical signs for a complex trait such as CM/SM cannot be overstated. More investigation is required to defining the pathology of symptomatic CM and its relationship with brachycephaly and miniaturization. This priority for future research can make a considerable and direct impact on dog welfare.

    The genetic investigation for canine CM/SM has been carried out in conjunction with human studies and it reaffirms how “Man and his Dog” have an enduring partnership. The progress made has been with the whole-hearted co-operation of breeders and pet owners supporting human sufferers of CM/SM under the umbrella “One Health.”
