Why Your Dog is Peeing Blood and What You Should Do

Making it a routine part of your life to pay attention to your dog’s urination habits can be a great indicator of possible conditions he may have. The sight of blood in your dog’s urine can no doubt send alarm bells to your head. Blood specks in urine, also referred to as hematuria should not be ignored. It is usually a signal of impaired health, and can sometimes be serious. There are many causes that lead to this from tumors to urinary tract infections.

What does it mean when a Dog Pees Blood?

If you notice blood specks in the urine or it appears very dark, see your vet as soon as you can. Even when there has been a recent injury, and you believe it is the cause of the presence of blood, be adamant about having a checkup as it could stem from a different issue. There is also the possibility of bacterial infections or life-threatening conditions. One of which, can be hematuria. Here are some of the telling signs your dog is suffering from hematuria.

  • The color of urine changes towards a reddish/pinkish shade
  • Specks of blood in your house
  • Your dog is urinating more frequently
  • He is causing too many accidents in the house
  • Your dog is wet all the time at areas where urine is leaking
  • He squats to pee many times in one round
  • He is licking the groin area frequently
  • When the condition is severe, your dog may cry restlessly during urination as a result of pain

Understand that hematuria can in other cases be accompanied by vomiting and diarrhea alongside other symptoms. The signs presented by your dog can vary depending on the root cause of the illness. Lethargy, for instance, could mean that your dog has been poisoned or is suffering from a prostate infection.

Why has my Dog Urinated Blood? -Causes  

Anything that causes bruising or inflammation of the urinary tract can result in blood in the urine of your dog. Various factors such as age, breed, or gender determine the causes of the condition. If your dog is old and you notice specks of blood, it could mean he has cancer in the kidneys or the urinary tract.

Bacterial Urinary Tract Infection

Bacterial UTI is one of the most common causes of blood specks in a dog’s urine. The infection is more prevalent in the female than the male breeds. If your dog is female, the location of her urethra exposes her to these bacteria. In this condition, your dog may have difficulty urinating or take longer than usual. If he or is constantly leaking the genitals and the odor of the urine is strong, it could be a sign of UTI or cancer. Transitional cell carcinoma is the most common type of dog cancer. This form of cancer is invasive and presents itself in tumors around the bladder. The initial diagnostics performed are urine culture and urinalysis. Although the condition can be painful, it can be treated using a round of antibiotics.

Urinary Stones

Urinary stones can be present in kidneys, bladder, the urethra, and ureters. The impact they have on your dog is dependent on the affected area, the number, and size. Some can be managed with medication, while others need surgery or be removed through a minimally invasive procedure.


Tumors often indicate the presence of cancer. However, some are benign, meaning they do not spread in the way cancer would. The problem is when they obstruct vital organs such as the kidney or the bladder. This could result in the dysfunction or failure of the organ obstructed. Blood in urine occurs when the primary organs are stressed or damaged.

Bacterial Infection in Kidneys or Bladder

Bacteria can affect the kidney and the bladder of your dog when it enters the body through the genital or rectal areas. One of the most telling sign is frequent squatting. When in this position, your dog is struggling to urinate but is not able because of too much pain. When the urine is either cloudy or bloody, it could signal blood infection that has affected the kidney or the bladder. Some of the infections that could be involved include:

  • Pyelonephritis: This is an infection that mostly occurs as a result of the blockage of the kidney stone. It can also result from UTIs. Obstruction is particularly very dangerous.
  • Sepsis: Blood infection can have a direct effect on the bladder or the kidney. It occurs when urine that has not decomposed is forced into the bloodstream. Bloody urine accompanied by back pain and fever is indicative of sepsis.


Pesticides and other toxic substances can be possible causes of bloody stool with mucus or urine. If you notice your dog has bloody stools or urinating blood and vomiting, this is an emergency and it can be fatal.

The Diagnosis of Bloody Urine in Dog

If your dog is vomiting bright red blood and is excreting blood, there is cause to seek the immediate help of a professional vet. Your vet will need a detailed account of your dog’s eventualities, from possibilities of a recent injury, ingestion of a new diet or toxic substances, or any supplements. They will then conduct a full body examination to look for potential abnormalities. A full blood count will also be carried out to investigate abnormal white and red blood cells.

The platelet levels will also be investigated. Urinalysis is a diagnostic tool that cannot be skipped. The pH of your dog will also be tested to check the glucose levels, the presence of red blood cells, full hemoglobin, and the mineral content. Should your vet detect a tumor, they may request for an X-ray to rule out tumors. Later on, a biopsy may be requested to find out if the tumor is malignant or benign.

Treatment when your Dog is Throwing up or Pooping Blood

Remedies vary depending on the underlying cause of blood in the urine, poo, or vomit of your dog. For your dog to be stabilized, intravenous fluids may be used if dehydration is detected. If the count of the red blood cells is too low, a blood transfusion may be employed in the treatment. For infections, antibiotics will be prescribed. For tumors, the diagnosis will direct your vet to either treat or refer you to an oncologist for specialized treatment.
