I’m so sorry Maddi is sick. You need to get her to a vet ASAP. Call your regular vet; even though they are closed at this hour, they will have a recording of how to reach a vet in case of emergency, which this is. I wish there was more I could offer you to try at home, but delaying getting her seen could make things worse. She needs IV fluids if she had that much bloody diarrhea.

Puppy sounds extremely ill and needs to see a vet immediately. There is nothing you can do for him at home, he needs veterinary attention now as his symptoms constitute a medical emergency. Please take him into an ER vet right away.

Oh no, poor Leon. It sounds like there is blood in his poop, and I would be concerned he could have a serious illness like parvo if he isn't fully vaccinated. His symptoms are severe and he needs to see a vet now. Please take him into one immediately.

I would rush Pippin into an ER vet now. He sounds quite sick if he's having bloody diarrhea, is lethargic, and is vomiting. He could have something serious like hemorrhagic gastroenteritis. Please take him into a vet now. Best of luck.

These signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). 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.

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.

My dog is very sick with bloody diarrhea. Do I really need a vet?

Regardless of whether you feel the vets in your town are "bad," Pitt needs medical attention. Not getting help for her is as troubling as suggesting the vets "don't care if animals die." If Pitt were a child with vomiting, diarrhea, and now rectal bleeding, I certainly hope you would take her to a doctor, even if you felt he or she wasn't the best in the town. So, pick the best of the "bad" vets and take Pitt in immediately. She may have eaten something, have a virus or bacterial infection, or be suffering from something more serious. The longer you wait, the more dehydrated and compromised she will become and the more treatment she will require to make her healthy again. I think it is unlikely that she has distemper and also unlikely that your other dog could get it. Don't wait - good luck and I hope Pitt gets better soon!

My dog has bloody diarrhea. What should I do and is it an emergency?

It sounds as Dahlia is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking her to the vet the first chance you get, she will need to be checked first, if the vet thinks it's a simple gastrointestinal infection she will need an antibiotic course and a special food for a few days in order to get better.

My dog has bloody vomit and dark red diarrhea. Is it an emergency?

If Sky has vomiting and diarrhea she needs to see a vet. Unfortunately her symptoms are very vague and could be from any illness or disease process. If Sky is a puppy I would be very worried about parvovirus. If she is an adult my first guess would be hemorrhagic gastroenteritis. Either way, she needs to see a vet. Please take her as soon as possible.

This is a medical emergency, and you cannot treat this at home. You have to take Poppy into a vet now. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.
