Brick Red mucous membranes in the dog may indicate - Increased perfusion Vasodilation (dilation of the blood vessels) due to early shock, sepsis, fever,systemic inflammatory response syndrome
You can rule out shock as he is getting better and the vet didn't find a fever it seems. So it sounds like its an infection and its good that you were sharp enough to get him to the vet quickly.
It sounds, as the Metronidazole is working well, like your dog has some sort of gastric infection that the med is curing. Dogs often drool when they feel nauseas. He might have grabbed a toad or gotten into something carrying a nasty bacteria. It may take until you are done with the meds before the blood vessel dilation goes away. If he is done with meds and there is still gum redness you may want your vet to check to see if early onset of periodontal disease or some sort of burn to the mouth is also an issue here.
If you had just applied a flea preparation or givne heartworm meds when this happened you may wish to discuss changing what you use with your vet to another brand or at least watch very carefully the next time you use them.
Hope this helps you!
