Imagine:
Going out for a run by yourself and you found a dog.
It was really skinny and it didn't look like it had been fed in months.
The dog hadn't seen you yet, so when you walked out the dog turned it's head towards you.
It came running towards you bearing it's teeth and bit you in the leg!
You started bleeding which attracted walkers and you couldn't run away because of the bite on your leg.
So you sadly died.
The End
