Why is my dog skinny, not eating, vomiting, lethargic, bloody urine?
Updated On September 23rd, 2025
Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 3 years and 5 months old
My dog has become very skinny, he isn't eating but a nibble, and pukes that up every once in a bit, is being lethargic and has spots of blood in his urine. He did the same thing about a year ago when I left him with a different person, but that was someone else, somewhere else. What's going on? Is he sick? Is he protesting me leaving him? What is it?

This sounds more like your dog has a chronic gastro-intestinal problem such as food intolerance, gastritis, chronic or acute pancreatitis, food indiscretion, or even a tumor, liver disease. He also may have a chrionic infection somewhere, e.g. in his prostate, which could be the cause of the blood in his urine, or kidney disease. The signs are too unspecific to pinpoint a cause, so you need to take Potato to your vet for an exam and blood work, and possibly xrays. Please make an appointment right away.

Wow, this is not good. The blood in Bane's urine could be due to prostate problems, a UTI, bladder stones, trauma to the bladder, leptospirosis, or bladder tumors. Weight loss can be caused by numerous things including systemic illness and cancer. You will need to take him into a vet this weekend or first thing Monday to have this diagnosed. Best of luck.

Hi, and thanks for your question. 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.
