My dog has bloody diarrhea, vomiting, and can't eat. What to do?
Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Daisy. Contact your local rescue groups, humane societies, low-cost clinics in your area and seek help. Persistent vomiting, bloody diarrhea and lack of appetite are emergent clinic signs due to fluid/electrolyte losses. This leads to dehydration, weakness, and further downward deterioration unless the vomiting stops and the appetite returns. I would advise taking Daisy to your vet as soon as possible to have her evaluated. Many causes are possible including intestinal parasites, dietary indiscretion (eating things dogs aren't supposed to), other dietary problems, gastrointestinal inflammation/infection from various sources, toxin exposure, foreign body ingestion, GI ulceration, side effects from drugs or products used, or even problems outside of the gut including pancreatitis, liver/kidney problems, among many others. Your vet can get a detailed history and perform a thorough exam. Once done, a diagnostic plan and preliminary treatment plan can be started. Most likely a minimum database of fecal/blood/urine tests and some x-rays will be advised. Treatment will be focused on the cause but early treatment could include fluids/electrolytes, anti-nausea/vomiting medicines, acid blockers, etc. Good luck with Daisy.
