I live in an area filled with hawks. Primarily they stick to the marsh and bog areas. But, the other day, while sitting in my yard, I noticed a red tailed hawk circling way above. Minutes later, he swooped down not 20' from me and grabbed a small rodent from the thicket and flew off. I have a guinea pig that loves to graze on the grass. Now, I'm fearful of bringing her out, even though she's in a large enclosed piggie playpen and I'm right by her side. I'm not sure about a 6 lb. dog but I don't doubt they would attempt it. It was truly frightening! Be careful!
