You'd also need to know what caliber the weapon was, how far away the shooter was from the target (the longer the distance the slower the bullet, and therefore it does marginally less damage), what kind of bullet it was (soft lead, soft lead with crosscut nose - illegal and very destructive - solid metal ball, full metal jacket), whether the impact was direct or glancing, what bones it hit, if any - there are a lot of variables.
What about a thirty-two semiauto (that could be what the bad guy shoots the dog with in the video clip) firing a full metal jacket round with an angled impact moving from just below and to the outside of the lowest point of the shoulder blade between the ribs and exiting the side below the armpit after a two-inch long penetration? That would produce a lot of bleeding and incapacitate the victim, but assuming prompt medical care would not mean permanent injury or a long recovery process.
Just a suggestion.
