Is there a possibility that there WAS something out there that he initially saw and barked and growled at that you didn't see?
My aussie will bark a very high pitched bark if she see's the 'bad dogs' I call the coyotes. She won't stop and she will pace at the slider.
If I look out and it is indeed a coyote, I will let her out to go run to the fence to bark and scare the coyote out of the back pasture, telling her what a good dog she is.
If on the other hand, it is the neighbors cat slinking into our side of the pasture looking for mice or a deer, I will tell her no barking the cat is ok the deer is ok. No barking at cats or dogs expecting her to stop barking. I don't let her out or would I drag her out there because I would think that would just reinforce barking at things she shouldn't be.
Your dog is young and you are a green dog owner. You will soon learn the different barks and what they mean.
