Bladder Carcinogen Exposures in Pet Dogs

Breed(s): -All Dogs
Study Location: University of Wisconsin, Madison
CHF-funded Grant: 02780

Bladder cancer in dogs can lead to blood in the urine, pain on urination, and urinary blockage. The underlying causes in dogs are not well understood. The aim of this study is to determine whether urinary exposure to certain environmental chemicals contributes to bladder cancer risk in the dog.

The results of this study may help us understand what causes bladder cancer in some dogs, and whether owners of these dogs share exposure to certain chemicals in the environment. Our goal is to find better ways to prevent bladder cancer in dogs and people.

Participation Requirements

Any dog diagnosed with bladder cancer (transitional cell carcinoma of the bladder or urethra), confirmed by tumor biopsy, genetic (BRAF) test, or examination of urinary cells, or any dog that is identified as an unaffected matched control.

Samples can be mailed.

Owner's Responsibilies

You collect a voided 25 mL urine sample (about 2 tablespoons) from your dog using a kit that we provide. Some dogs will have a brief ultrasound exam of their bladder. We will also ask you to fill out a questionnaire about your dog’s lifestyle. Your dog will not be given any medications or undergo any other procedures related to the study.
