I have a question. I found a puppy about a month ago. The vet thinks she is approximately 3 months old now. I put her on Wellness Just for puppy. She eats it fine and seems happy and healthy but has had loose runny stool since I found her and now she has a little bit of blood in her stool so of course I took her to the vet. No parisites or worms and parvo came back negative. But it seems to be still happening. Not everytime but randomly. The vet seems to think she is fine. She is eating drinking playing fine she isn't lathargic at all just loose stool with some blood. Anyone have any suggestions? Do I need to find another vet or could the food be causing her issues?
