The mineral deposits that, in people, become kidney stones, in dogs tend to find their way to the bladder instead. The mineral composition often varies by breed. The types of stones or crystals commonly found in Dalmatians, who are particularly prone to bladder problems, may be different from those that plague another breed.

Dogs with stone or crystals will often dribble or struggle to release urine, or pass urine that has blood in it. They may also whine or cry when trying to urinate.

If left untreated, stones can block the urinary tract, a potentially life-threatening problem that requires immediate veterinary intervention. Feeding special diets, available from your veterinarian, can dissolve certain types of stones. Surgery, antibiotics, or a flushing of the urinary system may also be necessary.
