Understanding Bladder Cancer in Dogs
Bladder cancer is a concerning condition that can affect our beloved canine companions. To better comprehend this disease, it’s important to explore the different types of bladder cancer and understand how it can spread.
Types of Bladder Cancer
The most common type of bladder cancer in dogs is transitional cell carcinoma (TCC), which accounts for approximately 90% to 95% of all bladder tumors. TCC typically originates in the transitional epithelium, which lines the bladder. Another type of bladder cancer that can occur in dogs is leiomyosarcoma, which arises from the smooth muscle tissue in the bladder wall (PetCure Oncology).
Metastasis and Spread
Bladder cancer in dogs has the potential to metastasize, or spread, to other parts of the body. Common sites of metastasis include the lymph nodes, lungs, liver, and, in male dogs, it can affect the prostate. In advanced stages of the disease, bladder cancer can spread to the lungs.
Understanding the types of bladder cancer and how it can spread is crucial for identifying potential symptoms and developing an appropriate treatment plan.

Recognizing Signs
The symptoms of bladder cancer in dogs can vary depending on the stage of the disease. In the early stages, common signs may include straining to urinate, urinary incontinence or frequent urination, bloody urine, licking the penis or vulva, decreased appetite, and redness or swelling at the penis tip or vulva (PetMD). In the late stages, additional symptoms may manifest, such as vomiting, weight loss, painful abdomen, reclusive behavior, exercise intolerance, difficulty sitting and walking, constant pacing, urine scalding, possible constipation, and anorexia. It’s important to note that these symptoms can be similar to other urinary tract conditions, making diagnosis challenging. Therefore, consulting a veterinarian for an accurate diagnosis is essential.
Here are some common signs of bladder cancer in dogs to be aware of:
- Blood in the urine (hematuria)
- Increased frequency of urination
- Difficulty or straining during urination
- Urinary accidents or incontinence
- Pain or discomfort during urination
It is important to note that these symptoms can also be associated with other urinary tract issues. Therefore, consulting a veterinarian for an accurate diagnosis is essential. For more detailed information on symptoms, refer to our article on bladder cancer in dogs symptoms.
Diagnostic Procedures
Diagnosing bladder cancer in dogs requires a combination of physical examinations, laboratory tests, and imaging procedures. The diagnostic process may include the following:
-
Physical Examination: During a physical examination, the veterinarian will carefully assess the dog’s overall health and look for any external signs of bladder cancer, such as swelling or abnormalities in the abdomen.
-
Urinalysis: A urinalysis helps evaluate the dog’s urine for the presence of blood, abnormal cells, and urinary tract infections. This test provides valuable information about the health of the urinary system.
-
Imaging: Imaging techniques, such as X-rays or ultrasound, may be used to visualize the bladder and detect any abnormalities, including the presence of tumors or masses.
-
Cystoscopy: Cystoscopy involves inserting a thin tube with a camera into the urethra and bladder to directly visualize the interior of the urinary tract. This procedure allows for a more detailed examination and may also involve collecting biopsy samples for further analysis.
-
Biopsy: A biopsy involves taking a small tissue sample from the bladder or suspected tumor to examine it under a microscope. This helps determine the presence of cancer cells and their characteristics.
By combining these diagnostic procedures, veterinarians can establish a definitive diagnosis of bladder cancer in dogs. It is crucial to consult a veterinarian if any symptoms or concerns arise. Prompt diagnosis and treatment can significantly impact the outcome for dogs with bladder cancer. For more information on bladder cancer in dogs, refer to our article on bladder cancer in dogs.
Treatment Options
When it comes to addressing bladder cancer in dogs, there are several treatment options available depending on the specific circumstances of the case. The primary treatment modalities for canine bladder cancer include surgical interventions, chemotherapy, and radiation therapy.
Surgical Interventions
Surgery is often considered as a treatment option for localized bladder tumors. The goal of surgical intervention is to remove the tumor and, if possible, preserve bladder function. The type of surgery performed depends on the location and extent of the tumor. In some cases, a partial cystectomy may be performed, where only a portion of the bladder is removed. In more advanced cases, a complete cystectomy, or removal of the entire bladder, may be necessary.
The decision to proceed with surgery is based on various factors, including the overall health of the dog and the stage of the cancer. It is essential for the veterinarian to assess whether the tumor is confined to the bladder or if it has spread to other parts of the body. Discussion with a veterinary oncologist can help determine the most appropriate surgical approach.
Chemotherapy and Radiation
Chemotherapy and radiation therapy are commonly used treatment options for bladder cancer in dogs. Chemotherapy involves the administration of drugs that target and destroy cancer cells. Commonly used chemotherapeutic agents for bladder cancer treatment in dogs include Doxorubicin, Mitoxantrone, and Vinblastine. These drugs can be given alone or in combination with nonsteroidal anti-inflammatory drugs (NSAIDs) like piroxicam.
Radiation therapy utilizes high-energy radiation to target and destroy cancer cells. This treatment modality may be recommended in cases where the tumor cannot be fully removed through surgery or to alleviate symptoms and improve the quality of life for the dog. Stereotactic radiation therapy is an advanced technique that delivers precise radiation doses to the tumor while minimizing damage to surrounding healthy tissue.
The choice of treatment, whether chemotherapy, radiation therapy, or a combination of both, depends on various factors such as the stage and type of cancer, the overall health of the dog, and the dog’s response to treatment. It is essential to consult with a veterinary oncologist to determine the most suitable treatment plan for each individual case.
It’s important to note that treatment for bladder cancer in dogs is aimed at managing the disease and improving the dog’s quality of life, as a complete cure is often challenging to achieve. The prognosis for dogs with bladder cancer is generally guarded, with an average life expectancy of 4-6 months for untreated dogs and 6-12 months for those receiving treatment (Northeast Veterinary Referral Hospital). Regular follow-up visits and close monitoring by a veterinarian are crucial to assess the response to treatment and make any necessary adjustments.
In the next section, we will explore the prognosis and life expectancy for dogs with bladder cancer, shedding light on the potential outcomes and factors that may influence the disease’s progression.

Prognosis and Life Expectancy
When it comes to canine bladder cancer, understanding the prognosis and life expectancy is crucial for dog owners. The prognosis for dogs with bladder cancer is generally poor, and the life expectancy can vary depending on various factors, including whether the cancer is left untreated or if treatment is pursued.
Untreated Cases
In untreated cases of bladder cancer in dogs, the average life expectancy is relatively short. On average, dogs with transitional cell carcinoma (TCC) of the bladder, the most common type of bladder cancer in dogs, live around 4-6 months without treatment (BluePearl Veterinary Partners). Bladder cancer typically spreads within a matter of months, and the life expectancy is not much longer than that.
Response to Treatment
With appropriate treatment, many dogs with bladder cancer can survive for 6-12 months after diagnosis. Treatment options for bladder cancer in dogs may include surgery, chemotherapy, radiation, or a combination of these options (Northeast Veterinary Referral Hospital). It’s important to consult with a veterinarian to discuss the best treatment approach for your dog based on their specific condition.
While treatment can potentially extend the life expectancy of dogs with bladder cancer, it’s important to note that transitional cell carcinoma is almost invariably fatal over time (PetMD). The goal of treatment is to improve the quality of life for the dog and manage the symptoms associated with the disease.
Recognizing the signs of bladder cancer in dogs, such as blood in the urine (hematuria), increased frequency of urination, difficulty or straining during urination, urinary accidents or incontinence, and pain or discomfort during urination, is crucial for early detection and intervention (VetMed Utah). However, these symptoms can also be associated with other urinary tract issues, so it’s important to consult a veterinarian for an accurate diagnosis.
Understanding the prognosis and life expectancy for dogs with bladder cancer can help owners make informed decisions about their pet’s care and treatment options. Regular veterinary check-ups, early detection, and appropriate treatment can improve the quality of life for dogs affected by this disease.

Advancements in Diagnosis
As veterinary medicine continues to evolve, advancements in diagnostic techniques have played a pivotal role in detecting and managing canine bladder cancer. Two notable advancements in the diagnosis of bladder cancer in dogs are the CADET Braf test and genetic testing.
CADET Braf Test
The CADET Braf test is a diagnostic tool that helps detect a specific gene mutation associated with bladder cancer in dogs. This mutation is commonly found in transitional cell carcinoma (TCC), which is the most prevalent type of bladder cancer in dogs. The CADET Braf test aids in early detection of bladder cancer, determines the extent of the disease, assists in selecting the best treatment approach, and monitors the response to chemotherapy.
The CADET Braf test involves a non-invasive urine sample collection from the dog. The collected sample is then sent to a laboratory for analysis. By detecting the specific mutation in the Braf gene, this test can confirm a diagnosis of TCC and provide valuable information for guiding treatment decisions (VetMed Utah).
Genetic Testing
Genetic testing is another advancement in diagnosing bladder cancer in dogs. This type of testing involves analyzing the dog’s DNA to identify genetic markers associated with bladder cancer susceptibility or the presence of specific mutations. Genetic testing can provide valuable insights into a dog’s predisposition to developing bladder cancer and aid in early detection and prevention strategies.
By identifying genetic markers or mutations related to bladder cancer, veterinarians can implement targeted surveillance and monitoring plans for at-risk dogs. This proactive approach allows for timely intervention and potentially improves the overall prognosis for dogs with a higher genetic predisposition to bladder cancer.
Both the CADET Braf test and genetic testing contribute to the early detection and management of bladder cancer in dogs. These advancements not only assist in confirming a diagnosis but also help guide treatment decisions and enhance monitoring protocols. As research continues to progress, these diagnostic tools may further evolve, providing even more precise and tailored approaches to the diagnosis and treatment of bladder cancer in our beloved canine companions.
