There are a growing number of consumers, supporters of veganism that include this lifestyle in their pets. In this context, the aim of this study was to prepare four different formulations of vegan canine biscuit by replacing wheat flour with inulin at the following concentrations: 0% (F1, control), 3% (F2), 6% (F3) and 9% (F4). Hydrolyzed soy protein concentrate (3,5%) and liophilized blackberry (5%) were also added to F2, F3 and F4. Differences were observed for color, hardness and specific volume between the biscuits. Sensory and palatability tests results showed higher acceptance of F3 and F4 formulations. Therefore, dogs will have a possible nutritional gain by preferring biscuits with inulin, hydrolyzed soy protein concentrate and blackberry.
