Was the drool watery or did have a thicker consistency?
They will sometimes expel water when being handled right after drinking, but it will look like water. If it looked thicker than that, it was probably something else. Dried mucus on his face is not a good sign. Might be time for a visit to the Vet.
BTW, punctuation is your friend. Not only are commas and periods nothing to be afraid of, they actually make it possible for others to read what you are saying![]()
