Help! I think I saw a werewolf?

Okay it was late at night and I had let my dog out to take a pee,and as I was standing at the door waiting for her to finish,she suddenly tucked her tail between her legs and ran into the house.She went under the sofa and started whimpering.Now I live near the woods and I could see this large furry creature in the bushes.It was bigger than a great dane and it growled at me! It had big teeth and yellow eyes,but thats all I really saw because I screamed and slammed the door shut.I almost joined my pooch under the sofa, I was so scared.I don't think it was a complete full moon that night,but I could see nearly 3/4 of it.We don't have bears in our woods and it was much bigger than a regular dog.Could I have seen a werewolf?
