Like a person, a dog can form stones in the bladder and enter the urethra.
They can be of various sizes, multiple or single, can spontaneously exit the channel or become stuck in it, blocking the lower parts of the urinary tract. Most often, the stones in the bladder let you know the painful urination, as well as the appearance of blood in the urine. With such symptoms, you need to urgently contact the veterinarian.
Types of stones in the bladder in dogs
Most of the stones that appear in the dog's bladder consist of ammonia and phosphoric acid magnesia. They are called struvites. The process of their formation is preceded by infection of the bladder. Sedimentary components of urine and bacteria form a focus around which ammonium phosphate is added. There are other stones in the bladder of the dog. They consist of uric acid and most often arise as a result of congenital disorders of urate metabolism.
Most of all, bulldogs and Dalmatians have such a genetic predisposition. The third type of stone contains cystine or calcium oxalate. Crystals of cystine were found in many dog breeds, in particular Newfoundlands. Silicon stones are more common in the dogs of German shepherds. Large or multiple stones, sometimes, can be probed through the stomach.
But an accurate diagnosis is established by X-ray examination, intravenous pyelography or ultrasound examination. The results of urine tests are also examined. Analyzed are stones removed surgically or released independently.
Treatment of stones in the urinary bladder in a dog
If the dog is fed according to a special diet, then in most cases the stones dissolve themselves within a few weeks or months. To do this, it is important to conduct a comprehensive examination and establish the type of stones in this animal. Thus, with struvite stones, a diet with a low content of protein and magnesium in combination with a food specially designed to treat such problems is necessary.
An example of such a feed is Royal Canin Urinary SO 13 . Stones with uric acid are excreted with the help of the preparation of allopurinol and a diet with low purine content. This same diet is suitable for cystine stones in combination with drugs that can dissolve cystine. A vegetarian diet, for example, Royal Canin Vegetarian Formula, helps prevent the re-formation of stones from silicon and calcium oxalate, which are removed only surgically.
If, in addition to stones in the bladder, an infectious process is found, it is also treated as cystitis. If the examination shows that the stones threaten to clog the urethra, they must be surgically removed. The same method is used when it is necessary to quickly relieve the pain or medications are contraindicated because of congestive heart failure.
