Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Happy. Dark red diarrhea can be a sign of intestinal bleeding from the stomach or the small intestines. I don't think this could be related to the beef she was given as that was 2 weeks ago and would be atypical anyways. I would advise that if this continues, worsens, or other signs develop, you should take Happy to your veterinarian to have her evaluated. Your vet can gather a detailed history and perform a thorough examination. From those, a diagnostic/treatment plan can be developed and started. Possible problems include intestinal parasites, gastrointestinal ulcer, toxin exposure, infection, inflammation, foreign body ingestion, nutritional problems, among many other things. Your vet may advise fecal/blood/urine tests and some imaging studies (x-rays, ultrasound) to get started. Once the cause is determined or suspected a treatment plan can be started. Treatment could include fluids, electrolytes, acid blockers, gastrointestinal protectants, deworming, antibiotics, medicines for diarrhea, etc. Good luck with Happy. I hope this resolves quickly and she recovers soon.
