Pet's info: Dog | Italian Greyhound | Female | spayed | 16 years old | 13 lbs
My 16 year old female Italian Greyhound is bleeding from her anus. It all started this evening. At first, she had dark brown diarrhea which looked like chocolate syrup. A few minutes later, she was leaking a thick, bright red (like fresh blood) mucus-like substance from her anus. Also starting this evening, she will not eat anything, including treats. Just this morning, she was fine. What are the possible causes? Should I take her to the emergency room tonight, or can I wait until the daytime?
