During attacks on decoys wearing suits the number off accidents are limited. The knees suffre the most. But with the muzzle attack on a "civil" person it's another ballgame. I've seen jaws broken, ribs... My father had in the sixties a dog which he couldn't compete with because she broke one or more bones everytime she had to gard an object wearing a muzzle.
Yesterday i got a little borred and i let my dog bite a little on a sleeve. Unfortunatly for me the sleeve wasn't thick enough. Today i found out that i've got 11 little puncture marks on my forarm in a straight line that is 7,4 cm long. One mark is 2mm off the line.
Meaning: Knowing that he came in fully excited and at full speed and that if his teeth are 4cm apart he went in at least 6 times with less than 2 cm of the centre mark.
