[Methods]Three factors affecting dyeing were selected including pH,concentration of dye and dyeing time. The L_9(3~3) orthogonal design was used to evaluate the hair coloring effect and the absorbance of cleaning solution after hair was dyed. [Results] The optimum pet dog dyeing process of plant hair dye was dye concentration of50 mg/mL,dye pH of 7. 5 and dyeing time of 1 h. [Conclusions] The coloring and fixing effects of the dye and dyeing process are good,which can lay a foundation for the development and utilization of plant dyes.展开更多

The tumor incidence of pet dogs has been increasing, raising widespread concern. In this study, retrospective analysis was performed with 246 tumor cases registered in Xi’an Animal Hospital, Northwest A&F University from 2009 to 2018. Correlations of sex, age and breed with tumor incidences were evaluated. The results showed that reproductive system tumors occupied the highest proportion (39.84%), followed by cutaneous tumors (28.05%), digestive tumors (18.70%) and ocular tumor (4.47%). Among the reproductive system tumors, breast tumors are the most common tumor in female pet dogs, especially for Pekingese (11.43%). Female dogs with high susceptibility to breast tumors were at the ages of 6–18 years old. As far as cutaneous tumors were concerned, the male pet dogs at all ages, particularly Golden Retrievers (17.39%), showed a high incidence. By contrast, male Samoyed aged from 4 to 13 years had the highest incidence (15.22%) of digestive tumors. In addition, pet dogs with ocular tumors mainly happened at the ages of 0–1 years and 6–13 years. Collectively, our findings are significant to develop effective measures of medical surveillance for pet dogs’ health and will provide insights for comparative oncology.展开更多
