    ABSTRACT: A retrospective cross-sectional study was used to analyse pyometra cases at five RSPCA Animal Hospitals across the UK from 2006 to 2011. A total of 1728 cases of pyometra were recovered from a female dog outpatient caseload of 78,469 animals, giving a total prevalence of 2.2 per cent over the study period. There was an annual increase in the incidence of pyometra within the population, while elective ovariohysterectomy caseload has declined. There were variations in breed and age at presentation. Bullmastiffs (P<0.0001), golden retrievers (P=0.001) and dogue de Bordeaux (P=0.008) were over-represented in the pyometra population when compared with the female dog outpatient caseload. Mean age at presentation was 7.7 years. Some breeds presented at a significantly lower age, including dogue de Bordeaux (mean age 3.3 years) and bullmastiffs (mean age 5.4 years), while others presented as older dogs, including Yorkshire terriers (mean age 9.4 years) and border collies (mean age 10.3 years). Surgical mortality rate at the Greater Manchester Animal Hospital was 3.2 per cent. Pyometra is of significant welfare concern, and also has cost implications, particularly in charity practice. These results serve to highlight this condition so that future change in charity practice caseload can be anticipated and strategies can be directed to improve animal welfare.

    ABSTRACT: An epidemiological survey of canine obesity was carried out in Beijing, China. Cases (n=2391, 7 districts) were collected at 14 animal hospitals between April 2008 and April 2011. The body condition score (scales of 1-5) was used to assess obesity of the dogs (Burkholder and Toll, 2000; Laflamme, 1997). Obesity rates were analyzed with respect to breed, age, sex, neutering, food control, feeding frequency, reproduction status, food type, nutritional supplements, living environment, feeding time, number of pets per household, feeding purpose, activity control, exercise duration, exercise status and exercise type. The overall canine obesity rate was 44.4% in this survey. The risk factors for dog obesity were food type (non-commercial food, OR=1.377, p<0.05), age (1-2y, OR=0.044, p<0.001), activity control (free activity, OR=0.685, p<0.05), neutering (intact, OR=0.629, p<0.01), sex (male, OR=0.628, p<0.001), feeding frequency (Once per day, OR=0.521, p<0.01). By dog breed, prevalence of obesity was high in pugs (70.7%), Cocker Spaniel (69.4%), Pekingese (51.9%), Pomeranian (54.6%) and Golden Retriever (51.9%). This is the first report of the epidemiology of canine obesity in China.

    ABSTRACT: Canine diabetes mellitus (CDM) remission is a rare event that is possible after the resolution of insulin resistance conditions, especially those related to the estrus cycle. A retrospective study was carried out at the Division of Veterinary Endocrinology from 2006 to 2011 to assess CDM remission rates after the resolution of problems associated with ovarian activity. Out of 117 female dogs diagnosed with CDM, six diabetes remission cases were identified and described after resolution of diestrus (1), or after ovariohysterectomy for pregnancy (1), ovarian remnant syndrome (1), and pyometra (3), even after initial presentation in severe diabetic ketosis or long after diagnosis (ovariohysterectomy was performed from 3 to 81days after diagnosis, and diabetes resolution was achieved within 4-39days after gonadectomy). Several factors may lead to diabetes remission. However, in these cases, ovariohysterectomy was crucial for the restoration of normal blood glucose levels, suggesting that diabetic bitches be spayed independently of the length of time after diagnosis.
