This was one brutal dog. He would hit me in the chest at 30 miles per hour.

FORCE = MASS X ACCELERATION Newton's Second Law of Physics

90 pounds of dog X 30 miles per hour = 2760 pounds of force that was applied to my chest, while the dog was in a muzzle.

Talk about taking the fight out of a man. This dog hurt me every single time I fought him. I dreaded convalescing the deep muscle bruises afterward.

To explain this photo, he had hit me in the chest. He rode me to the ground, and added 90 pounds to my body when I hit the ground.

I was totally disoriented, and did not know UP from NORTH. My instincts kicked in, and I rolled into the fetal position, on my side.(All the while, this dog is still leaving leather burns all over my body)

The dog tries to target my face, but it is hidden inside the fetal position. Now he uses his front feet, to grab me, and roll me onto my back. All of this, just so he could get to the soft chewy white facial meat.
