Possible Causes of Bloody Pee in Cani Corsi

Blood in urine, also known as hematuria, can appear at any age of a Cane Corso. Often it is a sign of an underlying problem.

Common causes of a Cane Corso peeing blood include:

Urinary tract infection

Infection of the upper or lower urinary tract system causes inflammation and bleeding which results in blood in the urine.

Ingestion of toxins can also lead a Cane Corso to pee blood. Potential poisons include plants, frogs, spiders, or household products, that can be accidentally ingested.

A Cane Corso peeing blood is one of the symptoms of poisoning which is also accompanied by other symptoms including vomiting, weakness, swollen stomach, difficulty in breathing, loss of appetite, nausea, and coughing.

The poison causes internal bleeding and results in a Cane Corso peeing blood. 

Bladder and Kidney stones

The presence of stones in the bladder or kidney results in blood in the urine.

Stones in these organs are formed by liver disease, high calcium blood levels, nutrient imbalance, and other conditions.

A diet with high protein and minerals increases the likelihood of formation of the stones.

The stones cause strain in these organs which bleed and result in a Cane Corso peeing blood.


Trauma or injury to the abdominal area can lead to internal bleeding which leads to blood in the urine.

Therefore if your Cane Corso has any injury caused by being hit or falling, this can lead to bleeding and bloody urine.

Female Cane Corso heat cycle

During its heat cycle, a female Cane Corso goes through various behavioral and physical changes. 

This includes bleeding, swelling of her reproductive area, frequent urination, and sheer determination in looking for a mate.
