I was savaged by dogs as a child and I carry visible scars on both wrists and forearms today, 50 years later. No reports were made to police or other authorities, who aren’t tracking such injuries anyway.
My friend Nikki’s face was ripped clean off her skull by someone’s friendly pet dog. Three surgeries (one to reattach, two plastic) and fifteen years later she’s doing pretty well.
You do know they go after children and small women, right? That’s the segment of the population you’re recommending that I shouldn’t bother learning how to defend.
EDIT: I actually try not to think of this stuff when it’s not necessary, so I forgot to mention that a dog tore the arm completely off a family friend in 2014. Luckily she survived and a dog mauling specialist reattached the arm.
