This is very sad and my thoughts are with her family.
I was also bitten by a neighbours dog on the calf muscle last winter. Lucky for me it was the first day I had worn my boarding trousers and socks, otherwise the injuries could have been much worse. However I was left with 3 holes in my leg.
Our other neighbours were so angry that the dog was destroyed. Sad as the owner was there when I was bitten, but the next time it could have been a child.
