You see, it is always in these trying times where it's always a good idea to know more about how your dog's body functions and what could've gone wrong along the way. In this article, we'll run you through what bladder cancer is all about, symptoms from its early to late stages, and ways to make your dog's life a bit better, one step at a time.


Of all urinary problems in dogs, cancer is probably the most common and most diagnosed among canines. According to The Purdue University College of Veterinary Medicine, cancer of the urinary tract in dogs can have an effect on the kidneys, ureters, urinary bladder, prostate, or urethraWithin the urinary system, the bladder is the location very often affected with cancer. Unlike cancer in dogs in other locations in the body, bladder cancer is strange, containing an estimated of 2% of all cancers in the dog. With more than 70 million pet dogs in the United States, however, even unusual cancers like bladder cancer, are problems for thousands of dogand their pet parents. 

To understand better, here's how your fur-baby's urinary system works: 

A dog's urinary system is consists of the ureters, the urinary bladder, the urethra, and the kidneys. The kidneys are the ones responsible for removing waste in the blood and balancing out the electrolytes in the body. Now the wastes filtered by the kidneys become urine, the urine moves to the bladder through the ureters, and is then collected in the bladder. Depending on the quantity of the urine, the bladder has the ability to expand its inner linings and walls. When your dog urinates, the urine is then eliminated via the urethra. 

There are many types of bladder cancer in dogs but the most common is the TCC or the Transitional Cell Carcinoma. This cancer begins as a tumor in the urinary tract and can metastasize and spread to other areas of the body like the bone, liver or skin.

Bladder cancer in dogs still doesn't have any known causes but genes, heredity, lifestyle, age, urination habits as there are some dogs who hold urine in for too long, persistent untreated urinary infections, etc. can pre-dispose your fur-baby into developing one in the long run.


As its causes are still unknown, preventative measures can be a challenge since you don't know exactly what you're avoiding. But here are a few things you can do to be able to guide your dog into a healthy lifestyle, away from those nasty bladder cancer cells.

Good exercise. Keeping your fur-baby moving will increase their blood flow and this appears to help reduce the risks of any form of cancer to develop. A good exercise can help your fur-baby get the daily activity his body needs to fight off cancer.

Low stress. Stress can cause a number of health problems in your dog that's why it's important to keep him anxiety-free.

Plenty of water. Having your fur-baby drink a lot of water will help his body flush out all those nasty wastes and will help lessen the chances of him developing urinary infections.

Pee often. Holding urine in for a long time can cause urinary problems. This is why it's very important to help your fur-baby pee on time. You can use pee motivators: every time after he wakes up, after playtimes, and after meals. What comes in must always come out.
