“…These structural changes within the cartilage matrix, alongside its reduced water content, lead to reduced functional rigidity, causing the tendency of tracheal collapse. About 25% of affected dogs show clinical signs by six months of age, supporting a congenital origin (Done et al , White & Williams ). Many dogs remain asymptomatic until later in life with degenerative change of the tracheal cartilage and secondary factors triggering the clinical syndrome of tracheal collapse (Done et al , Sun et al ).…”

“…About 25% of affected dogs show clinical signs by six months of age, supporting a congenital origin (Done et al , White & Williams ). Many dogs remain asymptomatic until later in life with degenerative change of the tracheal cartilage and secondary factors triggering the clinical syndrome of tracheal collapse (Done et al , Sun et al ). Secondary factors linked with the onset of clinical signs include airway irritants, chronic bronchitis, laryngeal paralysis, respiratory tract infection, obesity and tracheal intubation (Maggiore ) as well as postulated alterations of the elastic fibres in the dorsal tracheal membrane and annular ligament (Jokinen et al , Kamata et al ).…”

Tracheal collapse occurs most commonly in middle‐aged, small breed dogs. Clinical signs are usually proportional to the degree of collapse, ranging from mild airway irritation and paroxysmal coughing to respiratory distress and dyspnoea. Diagnosis is made by documenting dynamic airway collapse with radiographs, bronchoscopy or fluoroscopy. Most dogs respond well to medical management and treatment of any concurrent comorbidities. Surgical intervention may need to be considered in dogs that do not respond or have respiratory compromise. A variety of surgical techniques have been reported although extraluminal ring prostheses or intraluminal stenting are the most commonly used. Both techniques have numerous potential complications and require specialised training and experience but are associated with good short‐ and long‐term outcomes.

“…For example, hip dysplasia [ 5 , 6 ], gastric dilatation volvulus [ 7 , 8 ] and many neoplastic diseases [ 9 ] frequently occur in larger sized breeds of dogs. In contrast, smaller breeds of are predisposed to myxomatous mitral valve disease [ 10 ] and tracheal collapse [ 11 – 13 ]. Additionally, brachycephalic breeds are susceptible to several health concerns such as brachycephalic airway obstruction syndrome (BAOS) [ 14 , 15 ], dystocia in dams [ 16 ], digestive disorders and multiple eye conditions [ 4 ].…”

BackgroundThe morphology of dogs can provide information about their predisposition to some disorders. For example, larger breeds are predisposed to hip dysplasia and many neoplastic diseases. Therefore, longitudinal trends in popularity of dog morphology can reveal potential disease pervasiveness in the future. There have been reports on the popularity of particular breeds and behavioural traits but trends in the morphological traits of preferred breeds have not been studied.MethodsThis study investigated trends in the height, dog size and head shape (cephalic index) of Australian purebred dogs. One hundred eighty-one breeds derived from Australian National Kennel Council (ANKC) registration statistics from 1986 to 2013 were analysed. Weighted regression analyses were conducted to examine trends in the traits by using them as outcome variables, with year as the explanatory variable and numbers of registered dogs as weights. Linear regression investigated dog height and cephalic index (skull width/skull length), and multinomial logistic regression studied dog size.ResultsThe total number of ANKC registration had decreased gradually from 95,792 in 1986 to 66,902 in 2013. Both weighted minimal height (p = 0.014) and weighted maximal height (p < 0.001) decreased significantly over time, and the weighted cephalic index increased significantly (p < 0.001). The odds of registration of medium and small breeds increased by 5.3 % and 4.2 %, respectively, relative to large breeds (p < 0.001) and by 12.1 % and 11.0 %, respectively, relative to giant breeds (p < 0.001) for each 5-year block of time.ConclusionsCompared to taller and larger breeds, shorter and smaller breeds have become relatively popular over time. Mean cephalic index has increased, which indicates that Australians have gradually favoured breeds with shorter and wider heads (brachycephalic). These significant trends indicate that the dog morphological traits reported here may potentially influence how people select companion dogs in Australia and provide valuable predictive information on the pervasiveness of diseases in dogs.Electronic supplementary materialThe online version of this article (doi:10.1186/s40575-016-0032-2) contains supplementary material, which is available to authorized users.
