Weeds, burs?

Weeds, burs?

I apologize for the beginner question, but I was wondering if anyone has experience removing a large amount of those burs. I remember my dog having several of them in his fur last year, and I just now noticed a patch about a food wide by maybe 2 or 3 feet long hidden in the grass of fresh green burs. I did a bit of googling, but I'm unsure of which methods would work for this specific type of bur (I'm in area 9 if that helps), and which are also safe for animals and children. I don't want to trash what's left of the grass amongst this, if at all possible!
