my fiance and I have a 5yr old yellow lab mix, we have recently noticed that she is vomiting and has a lot of gas and diarrhea. However, this morning we noticed blood in her stool. She still has the runs but the vomiting has cleared up. When she was doing this before we changed the height of her water and food dishes and the vomiting seemed to go away. We are not sure if she got into anything while we were at work. So my question is how do we clear the blood in the stool up or should we just take her into the vet?
