My dog hasn't eaten for 3 days, is weak, and has bloody poop. Why?

Blood in the stool, even if it seems to "go away" and come back later, is never normal. The fact that it's accompanied by diarrhea suggests colitis, or inflammation of the colon, as opposed to some type of bleeding mass in the rectum or colon. Colitis can have a number of causes, including dietary indiscretion (eating something rotten or non-food), parasites, food allergies/food sensitivities, inflammatory bowel disease, or infection. Leah may improve with a diet change, perhaps a more digestible diet specifically for gastrointestinal problems. To assume it's a "tummy issue" could be to ignore causes that are treatable, and at this point she's not only having diarrhea but she also lost her appetite. It's been three days and she's not improving, so I recommend having her seen by her vet for labwork to include parasite testing, blood work, and urinalysis for starters. If all is normal consider a bland diet (as recommended above), and a probiotic supplement. Ultimately, she may need to have biopsies taken to diagnose the exact cause.

Poor Luna! She could have an infection (parvo, etc) or a parasite. Since she has bloody stool and is lethargic, she should be examined by a vet to determine the cause and treat. Your vet can test a stool sample to help diagnose and then prescribe medications to treat the problem. She might also need some fluids to prevent dehydration. Hope she gets better soon!

This behavior is suspicious for not feeling well and blood in the stool further supports that. I recommend to take in a sample of the stool for testing and have Lacey checked for parasites or an infection. Based upon the physical exam and the medical history, the doctor may recommend other diagnostics as well. In the meantime feed her a bland diet as this can help to relieve inflammation in the gut. I hope this helps and please feel free to post any additional questions.

It sounds like Baymax is very sick. Blood in the stool is very concerning for severe inflammation and this can be due to many things ranging from parasites to parvovirus to toxin exposure. Anytime a pet is sick beyond 24 hours they need to see the veterinarian and I recommend to get her examined today and the stool tested. For most conditions, the prognosis is better with earlier treatment. I hope she starts feeling better quickly and please feel free to post any additional questions.

I am so sorry to hear that your dog is so unwell. From what you are describing it sounds possible that he could have ingested a toxin, have a urinary tract infection, an infection of the prepuce, or an issue with his kidneys. Because he is so lethargic and not eating I would suggest a trip to the veterinarian as soon as possible to a diagnosis and appropriate treatment. If you can collect a urine sample to bring in that would be helpful. In the meantime you can try the following at home; Keep up fluids with; Pedialyte flavourless mixed with water 50/50 Low sodium chicken broth Encourage eating; Chicken boneless and cooked Low fat ground beef cooked Best of luck and ask any further questions you have here, we are here to support you.

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.

These signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). Dark feces could be compatible with a gastrointestinal bleeding in the upper part of the intestine. A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed.
