A dog with kidney stones faces the risk of infection, life-threatening uremic poisoning or sometimes death from stone blockage. Surgery can performed to remove stones that cannot be passed by the dog's system naturally or by a veterinarian's efforts to flush them out.
Types of bladder and kidney stones include struvite and uric acid stones, which have different causes than oxalate stones.
The dog may have blood in the urine, may seem to need to go to the bathroom more often, may spin around while trying to urinate, may be lethargic or may present with signs of severe pain.
If the stones cannot be flushed, the veterinarian will create an opening surgically to remove the stones from the bladder, kidneys or urethra.
Prevention and Solution
Struvite stones and uric acid stones can be sometimes prevented or dissolved by a special diet, but calcium oxalate stones will not disolve. Some medications, dry diets, water restriction, certain human foods and some supplements can be risk factors.
Some dogs are more prone to stone formation, such as the bichon frise, miniature schnauzer, Lhasa apso, Dalmatian, miniature poodle, and the shih tzu. Some dogs will begin to form new stones right after surgery.
The cost of having stone removal surgery can be a few thousand dollars at each occurrence. If your dog continues to form stones, you may have to consider the financial ramifications and the amount of suffering your dog can endure.
