My little Coco is 10 weeks 1 lbs 5 oz. I was wondering if any of you know whether it's ok for her to play in the grass. I mean, I don't want her to eat grass and get sick or contract something other doggies might have left behind. I know I'm really paranoid about her getting sick or hurt but we have to be right? So should she stay away from grass and parks for a bit?
