Why this about a dog? You don't have to look very far to find dozens of cases where 9mm, .40, or even .45 have failed to 1 shot stop. Maybe 9mm is less powerful than a .45... Maybe they are both spit in the ocean next to rifles. And humans have kept going after being hit with rifles.
Unless you are willing to move up to .44 magnum or rifles - accept the fact that none of these little pistol calibres are going to be effective at stopping pretty much anything.
