Walking at night

Now it is dark at night when Mom and I go out-and it's a little scary! I like to bark a lot when we first go outside to warn everything away. It is hard to see what is out there and noises seem stranger then normal. This all makes it harder for me to protect Mom. She thinks I am very skittish but I am just trying to see all that is around us and make sure nothing is coming to attack us. Usually I just try to pull her really fast around the block so that we get home faster-she tends to dawdle.
