My 6 month old munsterlander pup has just this morning started passing diarrhea with a bit of blood and mucus in it. Not loads, but enough to notice on inspection. The diarrhea is not watery, but pretty soft. The blood is a mid-red colour, not bright but not brown either (sorry for detailed description but I thought it is likely needed). She has passed some about 4 times already this morning, just a small amount each time. She was perfectly fine yesterday and seems to be fine in herself. Ate her breakfast with gusto, no vomiting. Should I panic and get her to the vets straight away or is it something just to be kept an eye on and see how she goes?
