Yes Oklahoma is right. I am sure it wasn't a person though. They don't have reflective eyes do they? It also kind of lunged when it ran too. Another thing is my dogs have a bark they do when they are freaked out versus a person being outside. The dog in the back kinda whimpers because he thinks he will be fed, if it is a person. He didn't do that. It was a different bark, like anxious or worried. Also,My husband put a baby monitor outside on the porch just in case. I might invest in some cameras for the outside, this month. This isn't the first time my dogs have freaked out. But it is the first time, I actually saw something in the yard. My husband went outside about ten minutes ago, didn't see anything.
