Thank you for submitting your question Dash. Blood in the stool can be a serious sign. What fecal tests did he have with his veterinarian? I typically test puppies for parvovirus, giardia, intestinal parasites such as worms and other protozoa as well as assessing the bacterial populations. This takes about 4 different tests to complete. If all of these tests come back negative or normal, I will typically still deworm the puppy and start an antibiotic. Diet should also be discussed. If he had a normal fecal test on his first puppy visit and has since developed this sign, he needs to see his veterinarian again today. The tests I described above will likely be warranted. Mucus and blood typically indicate inflammation in the colon. This is most commonly due to an infection, but can be diet related. Regardless,he will need treatment. I hope this information helps!
