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!

    It sounds as she 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. if the vet thinks it is more serious she will need a blood test and possibly an ultrasound in order to find out what is wrong.

    Robo sounds very sick, and I'd be concerned he could have parvovirus, may have eaten something rotten or toxic, could have a foreign body, or could have hemorrhagic gastroenteritis. He really needs to see a vet now, please take him into one immediately. Best of luck.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Shadow! Possible causes for not eating and blood diarrhea are: intestinal parasites, viral (especially parvo) or bacterial infections, dietary indiscretion, food allergy intolerance, reaction to human food or new treats/dog food. Shadow should see a Vet for blood work, fecal testing and parvo test. I am curious as to what you are "vaccinating" her with for vomiting, infection and red stool as these medications could be making things worse. I would recommend Hill's i/d or Royal canin GI puppy, metronidazole, deworming, a probiotic like Purina Fortiflora and something for nausea. She likely needs fluids as well. I wish Shadow the best!
