Anatomical differences of viscera between dog and sheep for animal product adulteration purposes and religious demands

In some countries, including Iran, there are tastes for consumption of viscera especially liver andkidney. The dog carcass has unsanitary nature and its consumption is forbidden in Islam. Theobjective of this research was to apply the comparative anatomy as a convenient way todistinguishing of viscera between sheep and dogs. In this research, we used samples from 3 dog and3 sheep carcasses showing no signs of pathology. After dissection, by referring to veterinaryanatomy reference books, all comparative characteristics of heart, kidney, lung and liver in thesetwo animals were extracted and finally these components were used to differentiate sheep viscerafrom dogs. A- Comparative characteristics of the heart: In this section, all the anatomical andmorphological characteristics of the heart between two animals are examined. B- Comparativecharacteristics of kidneys: In this section, all anatomical and morphological characteristics ofkidneys between two animals have been studied. C- Comparative characteristics of lungs: In thissection, all the anatomical and morphological characteristics of lungs between two animals havebeen accounted. D- Comparative characteristics of the liver: In this section, all anatomical andmorphological characteristics of the liver between two animals have been extracted. Overall, resultsshow noticeable differences in various parts of viscera between dog and sheep. The results of thisresearch can be used as effective, fast and accurate way to differentiate dog and sheep viscera, evenby ordinary people without anatomical expertise in cases of animal product adulteration purposesand religious demands.
