This study was conducted to develop an alternative feed option, addressing the demand for traditional extruded adult dog feed and exploring the possibilities of the development of vegetarian dog feed. Two types of extruded dog feed were formulated, namely a vegetarian variant (T1) and a non-vegetarian one (T2). The formulations were further subjected to a comparative study along with commercially available dog feed T3. On microbiological evaluation, both formulations revealed a total viable count of 2030 CFU at 10-1 dilution, which became negligible in further dilutions, indicating minimal bacterial contamination. The results of in vitro digestibility study demonstrated that the digestibility of dry matter and crude protein was significant (P ≥0.05) higher in T1 and T2 group in which in house prepared vegetarian and non-vegetarian food was fed as compared to T3 group in which commercial food was fed, however, the digestibility of ether extract was significantly higher in T1 and T3 group as compared to T2. Moreover, the digestibility of organic matter was significantly lower in T2 group then T1 group but the digestibility of organic matter remains comparable in commercial food with vegetarian (T1) and non-vegetarian (T2) food. These findings highlight that in housed prepared vegetarian and non-vegetarian were equal good to commercial dog food in term of nutritional quality and safety.
