Owners Report High Rates of Pancreatitis in UK Miniature Schnauzers

Owners of Miniature Schnauzers in the United Kingdom report far more pancreatitis in their dogs than large veterinary record studies have detected, according to a new owner survey-based study published in Companion Animal Health and Genetics. In the survey, 7.6% of dogs were reported by their owners to have been diagnosed with pancreatitis, a figure the researchers describe as high and notably different from previous estimates drawn from clinical records. The study, led by researchers including Arielle Johnson-Pitt, Cathryn S. Mellersh, Collette Taylor, Brian Catchpole and Lucy J. Davison, set out to examine Miniature Schnauzer health from the owner perspective and to explore relationships between reported pancreatitis and other conditions in the breed.

The survey ran online for one month, in May 2023, and was open to UK-based owners of Miniature Schnauzers. It was advertised and distributed through breed clubs, social media and newsletters, and included directed disease-specific questions with yes or no answer formats alongside opportunities for free-text reporting. In total, responses were received from 4,786 owners, of which 2,910 contained sufficient data for analysis; 2,669 respondents completed the entire survey. Each survey entry corresponded to a single animal, and owners with more than one dog completed a separate response for each. The researchers screened bodyweight for extreme values using Tukey’s fences to identify data entry errors, excluded implausible ages from age-based analyses, and coded missing answers as “not recorded”. Ethical approval was obtained from the University of Cambridge Department of Veterinary Medicine’s Ethics and Welfare Committee.

The analysed cohort was dominated by neutered animals: 73.8% of dogs were reported to be neutered, and 47.1% were female. The median age was 5.5 years. Most owners, 72.9%, rated their dog’s body condition as ideal at 3 out of 5, while 5.7% reported a body condition score of 4 out of 5 and 0.6% a score of 5 out of 5, giving an owner-reported percentage of overweight or obese Miniature Schnauzers of 6.3%. The adjusted mean bodyweight was 9.2 kilograms, with males heavier at a reported mean of 9.9 kilograms than females at 8.5 kilograms. Free-text data were available from 1,638 responses and were analysed using qualitative content analysis, in which a coding frame of 40 unique codes was built from a subset of 200 responses and then applied to the remaining 1,438, with similar codes grouped into 22 broader categories.

Across the specific disease questions, the most prevalent conditions owners reported fell into the categories of dermatological disease, mass-associated disease and allergic disease, a pattern the authors note is broadly consistent with previous veterinary studies of the breed and of the wider canine population. Pancreatitis, however, stood out among the specifically probed pancreatic and endocrine conditions: owners reported it in 220 of 2,910 animals, or 7.6%. By comparison, heart murmur was reported in 6.6% of dogs, nephroliths or uroliths in 1.9%, diabetes mellitus in 1.1%, hyperlipidaemia in 1.0%, hypothyroidism in 0.4% and hyperadrenocorticism, also known as Cushing’s syndrome, in 0.4%. Where owners reported the age at which pancreatitis was diagnosed, 17.2% of cases, 35 of 203, were diagnosed between one and two years of age, indicating that some dogs develop the disease remarkably early in life.

To probe the relationships between pancreatitis and other factors, the researchers built a multivariable logistic regression model comparing the 220 dogs with a reported pancreatitis diagnosis against 2,459 dogs without one. Sixty-seven variables were assessed at the univariable level, of which 17 were taken forward, and a manual forwards stepwise approach was used for model building. The final model contained three variables: diabetes mellitus, diet and age at neutering. Dogs with a reported diabetes mellitus diagnosis had 4.54 times the odds of a reported pancreatitis diagnosis, with a 95% confidence interval of 1.7 to 11.6 and a p-value of 0.002. A reported pancreatitis diagnosis was also associated with being fed a low-fat diet, with an odds ratio of 7.07, a 95% confidence interval of 3.2 to 16.9 and a p-value below 0.001, an association the authors suggest most likely reflects dietary management of the disease rather than a cause, since low-fat food is commonly recommended for dogs with pancreatitis or hyperlipidaemia.

The model performed well by its own statistical criteria. The likelihood ratio test comparing the fitted model to the null model was significant at p below 0.001, and the smaller Akaike information criterion values indicated that the included variables collectively improved model fit. McFadden’s pseudo-R2 was 0.27, which the authors describe as indicating good model performance, and receiver operating characteristic analysis produced an area under the curve of 0.80, with a 95% confidence interval of 0.77 to 0.84, suggesting good discrimination between dogs with and without reported pancreatitis. No specific age-at-neutering category was individually significantly associated with a reported pancreatitis diagnosis, although the variable as a whole significantly improved model fit. Interaction terms involving diabetes mellitus were explored but not included in the final model because of the small number of diabetes cases.

The timing of diagnoses offered further clues about how pancreatitis and diabetes mellitus relate in this breed. Among the 12 dogs reported to have both conditions, 7 of 12 owners reported the same age of diagnosis for both diseases, and the remainder reported that pancreatitis was diagnosed two years after diabetes, although there was no significant difference in the ages of diagnosis of the two conditions overall. The reported prevalence of diabetes mellitus in this population, 1.1%, is higher than the reported general canine population prevalence of 0.26% to 0.38% and is consistent with previous studies reporting increased diabetes risk in Miniature Schnauzers. The authors note that whether inflammation of the exocrine pancreas precedes diabetes or arises from uncontrolled diabetes remains contentious in dogs, and that either sequence appears possible; in this survey, pancreatitis was typically diagnosed at the same time as, or before, diabetes.

Hyperlipidaemia told a different story. The median reported age of diagnosis was 7.5 years, consistent with previous observations that the condition typically develops later in life, and among dogs diagnosed with both hyperlipidaemia and pancreatitis the ages at diagnosis did not differ significantly. Yet the overall owner-reported prevalence of hyperlipidaemia was strikingly low: 1% of all Miniature Schnauzers in the survey, rising to only 3.3% of dogs over the age of nine years. The authors contrast this with a study from the United States that reported more than 75% of Miniature Schnauzers over the age of nine have hypertriglyceridaemia, with an overall breed prevalence of 32.8%. They suggest the discrepancy might reflect a lack of testing, or genetic or environmental differences between the UK and US populations. Pancreatitis, by contrast, was diagnosed significantly earlier in life than hyperlipidaemia in this cohort, and the early onset of some pancreatitis cases, at one to two years of age, raises the possibility of a primary disease rather than pancreatitis secondary to conditions such as hyperlipidaemia, diabetes mellitus or hypercortisolism, which are known to predispose older dogs to secondary pancreatitis.

The study’s context is a long-standing puzzle in Miniature Schnauzer health. The breed is considered predisposed to pancreatic diseases including pancreatitis and diabetes mellitus, yet a large-scale epidemiological assessment of Miniature Schnauzers under primary veterinary care in the UK reported periodontal disease, enteropathies and cutaneous disease as the most common disorders, with no pancreatic conditions reported at all. That primary care study did record vomiting as a disorder in 5.1% of the breed, and the authors of the new study note that some of those dogs might represent undocumented or undiagnosed cases of pancreatitis, particularly given that only 20.7% of clinical problems receive a definitive diagnosis in veterinary practice and that testing for pancreatitis has limited sensitivity and specificity. The new findings therefore highlight a discrepancy between primary care documentation and owner reporting that the authors say requires further investigation.

The researchers are careful to spell out the limitations of an owner-reported design. Owners’ testimony might not accurately reflect the presence or absence of confirmed clinical disease, and owners and vets may differ in their criteria for a pancreatitis diagnosis; reports of straightforward diagnoses such as diabetes with insulin treatment are likely more reliable than complex diagnoses such as pancreatitis. Results may also be subject to reporting bias, since owners of affected dogs may have been more motivated to participate, and participation was limited to people reached through the survey’s distribution pathways, introducing potential selection bias. Only 12 dogs had both pancreatitis and diabetes, a small number that the authors say underscores the need for targeted studies in larger populations. The data were also time-restricted to owner recall within three months in 2023. Despite these caveats, the authors argue that incorporating owner-reported data into breed health research is valuable, that combining owner and veterinary perspectives may improve understanding of breed health, and that future studies should focus on aligning findings in clinical records with owner perceptions in the same dogs to better inform patient treatment and welfare.
