Yes. One of the largest genetic differences between domestic dogs and wolves is that they evolved to digest carbohydrates. Dogs developed many more genes that produce amylase enzymes to break down starches. It’s hypothesized that these adaptions occurred to digest a more omnivorous diets as they evolved alongside their human companions. Dogs also have pancreatic amylase (as well as other carbohydrate enzymes) which allow them to digest >95% of starches (similar to humans).
