Yes. May be nothing to worry about if there aren't any other symptoms. Is he eating? How is his demeanor? Normal/happy? Lethargic? Are stools normal?
When our dog gets sick, the first sign is the growly stomach. She has IBD and is prone to inflammation, bloody stool, lethargy, loss of appetite, etc. Not saying your dog has that at all. If his appetite and spirits are good, he could just have an empty tummy and needs food. After a long day playing, our dog's tummy will sometimes get a little growly. It settles down once she eats.
Hope he's ok.
