There are a number of different kidney problems, such as incontinence, bladder stones or crystals in the urine, UTIs, cancer, or obstruction to the urethra, and some of them can't be prevented, such as chronic kidney failure or cancer which may naturally occur in older dogs. UTIs in dogs are caused by bacteria entering the urethra. Crystals in the urine can by caused by supersaturated urine, which happens when a dog has to hold their bladder for a long time. For good kidney health, I recommend making sure Bruno is let out to urinate on a regular basis, not being left longer than eight hours between peeing, making sure he always has a source of fresh water available, keeping him at a healthy weight, and making sure he eats a high quality diet.
