I own 3 months old female boxer pup. Have her since she was 7 weeks old. For last 3 weeks she has about a tee spoon of blood dribling right after her feces, she has also lots of mucus (yellow slime in chunks). Vet said that mucus is normal, and blood can be from eating grass? Pup eats same food sice she is eating - Eukanuba for large breeds pups. What do you think?
I recommend that her stool be tested for parasites. Different parasits can cause this including coccidia and/or giardia. Good luck, vetcare
