Bright red blood means the bleeding has occurred in the colon or large intestine--this is the end of the intestines. Stomach ulcers or a higher intestinal bleed will result in dark blood in the stool because this blood has been digested.
Metronidazole is a great treatment for bloody diarrhea. It usually takes 12-48 hours for effect. I would not be concerned with a small amount of blood after one dose.
If further blood is noted in the stool please contact your veterinarian. Your veterinarian is the best person to go to for advice as they know your dog and her case.
Other at home remedies that can help with diarrhea is plain yogurt (a good probiotic) and canned pumpkin (fiber). You can give 1-2 teaspoons added to food twice a day.
