Should I Be Worried About Blood In My Pet’s Urine Or Feces?

Most of us know that if we notice blood in our urine or feces, we should arrange to see a doctor pretty promptly. But what if we notice our pet having the same problem? Should we be worried if we spot blood in our pet’s urine or bowel movements? Here is what you need to know about what seeing this symptom could mean and when you should arrange to speak to your veterinarian.

Causes of blood in your pet’s urine or feces

Unsurprisingly, there can potentially be a variety of different things that could cause your pet to have blood in his pee or poop. When it comes to your pet’s stools, there are two different types of blood that you might notice. The first is fresh, red blood while the second is dark, tarry-type blood. The appearance of the blood that you spot will help determine what might be causing it.


Your pet might have blood in his stool if:

-         He has parvovirus. This is a serious virus that is most often seen in puppies or unvaccinated adult dogs. Parvovirus can be deadly, so your pet must be seen by a vet immediately.

-         He has a parasite infestation. Parasites are one of the most common causes of blood in stools, and in particular, hookworms, whipworms, and roundworms. These are fairly easily treated.

-         He is suffering from inflammatory bowel disease, a condition that is virtually the same in pets as it is in humans and can be managed through dietary changes and medications.

-         He has colitis, which is an inflammation of the colon or large intestine, which also causes diarrhea as well as blood on stools.

-         He has a form of cancer or is bleeding internally. Bleeding tumors, polyps or internal bleeding can cause animals to pass anything from fresh, red blood in their stools to darker, tarry blood.


Your pet might have blood in his urine if:

-         He has a bladder or kidney infection.

-         He has kidney stones or bladder stones.

-         He has a urinary tract infection (although these tend to be more common in female pets)

-         He has a prostatic disease – one of a number of different conditions that can affect your pet’s prostate gland.

-         You have a female pet who is in heat and experiencing the animal equivalent of menstruation.

-         He has a cancerous or non-cancerous tumor.

As a general rule, blood in your pet’s urine or feces should never be ignored, particularly if it is also accompanied by at least one other symptom. It is far better to arrange to have your furbaby checked out and find that there is nothing wrong than to ignore the problem, only to later find that prompt diagnosis and treatment could have enabled him to avoid serious and potentially deadly illness.
