I can't find many studies regarding gallbladder emptying times in dogs. In particular, I wonder if this observation has ever been used as a contribution in legal cases, for example to speculate on the time of the last meal. I am examining a dog killed by a gunshot wound: the stomach is full of food only partially digested, but the gallbladder is not empty (the bile duct was normally patent). Can I infer something about the time elapsed since eating its meal?
