Understanding Bladder Cancer in Dogs
Bladder cancer in dogs is a serious health condition that can affect our beloved furry companions. Understanding the basics of this disease, including its overview and the breeds at risk, is crucial for early detection and intervention.
Overview of Bladder Cancer
Bladder cancer, also known as urothelial carcinoma, is a relatively rare form of cancer in dogs, accounting for approximately 1 to 2 percent of all canine cancer cases. However, it is important to note that the incidence of bladder cancer in dogs is on the rise, with over 50,000 dogs affected each year (American Kennel Club).
This type of cancer primarily affects the urinary bladder, which is responsible for storing urine before it is eliminated from the body. The growth of malignant cells in the bladder can lead to various complications and discomfort for the dog.
Risk Factors and Breeds
Certain dog breeds have a higher predisposition to bladder cancer compared to others. Among these breeds, Scottish Terriers, Shetland Sheepdogs, Beagles, West Highland Terriers, and Wire Hair Fox Terriers are commonly associated with an increased risk of developing bladder cancer (Northeast Veterinary Referral Hospital). Middle-aged and senior female dogs of these breeds are particularly susceptible to bladder cancer.
While these breeds have a higher genetic predisposition, it is important to note that bladder cancer can affect dogs of any breed or mixed breed. It is always advisable to be vigilant and look out for potential signs and symptoms of bladder cancer, regardless of the breed.

Signs and Symptoms
Recognizing the signs and symptoms of bladder cancer in dogs is crucial for early detection and prompt treatment. While the symptoms may vary from dog to dog, there are common signs to be aware of when it comes to bladder cancer in dogs.
Recognizing Early Signs
Signs of bladder cancer in dogs often involve urinary issues that may initially be mistaken for other urinary tract conditions like stones or infections. It’s important to pay close attention to any changes in your dog’s urinary habits. Some common early signs of bladder cancer in dogs include:
- Hematuria (blood in the urine): The presence of blood in your dog’s urine is a significant indicator of a potential problem.
- Straining to urinate: If your dog appears to be struggling or straining while urinating, it could be a signal of bladder cancer.
- Repeated UTIs: Dogs with bladder cancer may experience recurrent urinary tract infections that do not resolve with treatment.
- Frequent small urinary incidents: Dogs with bladder cancer may urinate more frequently, but in smaller amounts, due to the presence of a tumor affecting normal urinary function.
Diagnostic Process
Diagnosing bladder cancer in dogs can be challenging as the symptoms can mimic those of other urinary tract conditions. If you notice any of the aforementioned signs, it’s crucial to consult with your veterinarian for a proper diagnosis. The diagnostic process may involve the following steps:
-
Physical examination: Your veterinarian will conduct a thorough physical examination of your dog, including palpation of the abdomen to check for any abnormalities.
-
Urinalysis: A urine sample will be analyzed to check for the presence of blood, abnormal cellular structures, or signs of infection.
-
Imaging tests: X-rays, ultrasound, or other imaging techniques may be used to visualize the bladder and surrounding structures, allowing veterinarians to identify any masses or abnormalities.
-
Biopsy: If a suspicious mass is detected, a biopsy may be performed to confirm the presence of bladder cancer. This involves obtaining a small tissue sample from the affected area for laboratory analysis.
Early detection and accurate diagnosis are crucial for effective treatment and improved outcomes. If you suspect your dog may be exhibiting signs of bladder cancer, it’s important to consult with your veterinarian promptly. They will guide you through the diagnostic process and provide the necessary care for your beloved pet.

Types of Bladder Cancer
Bladder cancer in dogs can manifest in different forms. The two primary types of bladder cancer seen in dogs are transitional cell carcinoma and leiomyosarcomas.
Transitional Cell Carcinoma
Transitional cell carcinoma (TCC) is the most common type of bladder cancer in dogs, accounting for approximately 90% to 95% of all bladder tumors. TCC typically originates from the lining of the bladder and can progress to affect the urethra, ureters, and other parts of the urinary tract. Certain breeds, such as Scottish Terriers, Shetland Sheepdogs, and Beagles, have a higher predisposition to develop TCC (American Kennel Club).
As TCC progresses, it can invade the bladder wall and potentially spread to nearby lymph nodes, lungs, liver, and even affect the prostate in male dogs. Early detection of TCC is crucial for treatment and management. To learn more about the symptoms of bladder cancer in dogs, refer to our article on bladder cancer in dogs symptoms.
Leiomyosarcomas
Leiomyosarcomas are another type of bladder cancer that can occur in dogs. Unlike TCC, which arises from the lining of the bladder, leiomyosarcomas develop from smooth muscle tissue in the bladder wall. Although less common than TCC, leiomyosarcomas can still pose a significant health concern for affected dogs.
Similar to TCC, leiomyosarcomas can invade surrounding tissues and potentially metastasize to distant sites in the body. Diagnosis and treatment of leiomyosarcomas require the expertise of a veterinary professional.
It’s important to be aware of the signs and symptoms of bladder cancer in dogs, as early detection and intervention can greatly impact the prognosis. Additionally, certain breeds may have a higher predisposition to developing bladder cancer, so understanding the risk factors associated with specific breeds is important. To learn more about breed-specific risks, refer to our article on bladder cancer in male dogs and bladder cancer in female dogs.
By understanding the different types of bladder cancer that can affect dogs, pet owners can be more vigilant in spotting potential symptoms and seeking appropriate veterinary care. Timely diagnosis and treatment can significantly improve the outcome for dogs with bladder cancer.
Treatment Options
When it comes to treating bladder cancer in dogs, there are several options available depending on the specific case and the stage of the cancer. Treatment options may include surgical interventions, chemotherapy, radiation therapy, or a combination of these approaches.
Surgical Interventions
Surgery is often a primary treatment option for bladder cancer in dogs. The goal of surgery is to remove the tumor and any affected surrounding tissues. The type of surgical procedure performed may depend on the location and extent of the cancer. In some cases, a partial cystectomy, which involves removing a portion of the bladder, may be performed. In more advanced cases, a complete cystectomy, or removal of the entire bladder, may be necessary.
The effectiveness of surgery in treating bladder cancer can vary depending on the stage and type of cancer. It is often recommended as part of a multimodal treatment approach, along with other therapies such as chemotherapy or radiation.
Chemotherapy and Radiation
Chemotherapy and radiation therapy are commonly used in the treatment of bladder cancer in dogs. Chemotherapy involves the use of drugs to kill cancer cells or slow down their growth. The effectiveness of chemotherapy can range from 40% to 70% in shrinking tumors or slowing their growth. Piroxicam, a non-steroidal anti-inflammatory drug, has shown positive results in treating transitional cell carcinoma (TCC), with some dogs experiencing tumor remission.
Radiation therapy, on the other hand, uses high-energy beams to target and destroy cancer cells. It is often employed after surgery to eliminate any remaining cancer cells or as a palliative treatment to relieve pain and improve quality of life.
The specific treatment plan, including the combination and duration of chemotherapy and radiation therapy, will depend on the individual dog’s condition, the type and stage of bladder cancer, and the recommendations of the veterinarian.
It’s important to note that while treatment can provide an improved quality of life for a period of time, the long-term prognosis for bladder cancer in dogs is generally poor (BluePearl Veterinary Partners). Dogs diagnosed with bladder cancer typically live approximately 4-6 months without treatment and 6-12 months with treatment (Northeast Veterinary Referral Hospital). However, each case is unique, and the prognosis can vary depending on factors such as the stage of the cancer, the overall health of the dog, and the response to treatment.
