It is believed that dogs started to become domesticated around 14,000 years ago. People found dogs to be useful in all sorts of ways, and soon put them to work. Evidence unearthed in Jordan shows that dogs (that were still close to their wolf ancestors) helped human hunt animals almost 12,000 years ago.
The study, by archaeologists from the University of Copenhagen and University College London, looks at animal bones found in a Neolithic settlement known as Shubayqa 6, established 11,500 years ago, in the Black Desert of northeast Jordan. The bones suggest that the site’s residents were using their dogs to help them hunt, a finding that can help clarify the murky origins of dog domestication. It hasn’t been clear, the researchers write in a release, whether that process was deliberate or accidental, but this new evidence of canine-assisted hunting implies that these Stone Age humans were highly dependent indeed on their dogs.
The clues come from bones of prey, including bones that had been digested. Read about the research at Atlas Obscura.

Of course, for rifle bullets, feet and feet of fat would be necessary. However, for small arms (pistols and revolvers), the experiment is invalid, because:
- most pistol bullets aren't as heavy as the ball bearing they used. Ball bearings are usually made of steel. Bullets are lead, antimony and, sometimes copper. A steel ball bearing of the same size of a bullet is usually heavier than the bullet.
- The 9mm Luger is a fast cartridge, but doesn't come close to 500 m/s (usually, 350 m/s for a 124 gr bullet)
- Most people are shot by small arms, not rifles, so, an appropriate experiment would be to use a common gun, like a 9mm or even a .38 Spl, which I know for fact than can be stopped by fat. Even a heavy leather jacket will slow a .38 Spl down enough to lower its damage to a minimum.
- A hollow point bullet, which expands on hitting soft targets, will deaccelerate considerably when traveling through the medium.
- Even when a bullet can be stopped by fat, what is most damaging is not the perfuration made, it's also the effect of the thermostatic shock that damages internal organs.
- AFAIK, only muzzle loading guns use round (as in "round ball") bullets, but then, their speed is very limited, they are made of lead, and their surface is not near as finished as a ball bearing.
Pretty safe to say that being shot is bad. Being fat is bad too. Avoid both to live a long life.
