Did you feed him before taking him to the walk?
He might have eaten something on the way that you might not have realised at that time which could have caused the vomit.
There's probably no real need for big concern if this happened only once. If it happens again take him to a vet and keep his stomach clean for at least 24 hours. Give him very little boiled rice other than that just water.
