We had a similar problem with our cat; blood in urine. They gave her a shot of vitamin B and i think antibiotics. She was better in less than a week and it only cost a little over $100.
Gina. What color is the blood and how many times has this happened? What's your dogs other demeanor like?
If she still has blood in her stool I would take her in, blood in stool is never a good thing. If it was just a 1 time thing and you haven't seen it since you're okay not to take her in.
