KIDNEYS AND URINARY BLADDER Infection
The causes of the renal problems can be very diverse: infections, gall stones, accidental injuries, poisoning and the autoinmunity syndrome (the kidneys are attacked by the dog's own immune system).
However, the most common one is the consumption that is produced through the year with use, called in scientific terms Chronic Interstitial Nephritis.
The first symptom of any renal problem is the increase of thirst. Lost of appetite and weight and bad breath. If not treated then, vomiting and the intense dehydration come and in extreme cases, maybe also death. If the kidney doesn't work correctly, the dog begins to accumulate phosphorus and other disposal products resulting with the dissociation of ingested proteins prior to its assimilation as the urea and all these substances contribute, at the same time, to make the state of the kidneys even worse.
The blood and urine tests permit early diagnosis of renal problems and therefore, the treatment before the disease gets more difficult or maybe impossible to heal. A diet low in phosphorus and with appropriate quantity of good quality proteins contributes in a great deal to slow down the development of the disease.
If the dog's urinary bladder is sick, the dog can either suffer from incontinence or difficulties to urinate, sometimes bleeding due to the effort which would dye the urine red. The main problem would be just a simple cystitis, frequent infection in female dogs. If the problem isn't solved with antibiotics, radiographs will be taken to look for possible causes as gall stones or tumors.
URINARY INCONTINENCE Failure
Dogs of both genders can suffer from urinary incontinence for many causes, among which we can mention the prostate and bladder problems. However, as it is mostly suffered by old dogs, most of the time it is mainly cause by the aging and the relaxation of the sphincters and/or cognitive mistakes (senile dementia) that sometimes come with it. Remove urine smell from carpet. The debilitation of the bladder sphincter is pretty normal on castrated female dogs and can usually be handled with treatment. No dog that is very old is safe from senility. Many medicines, even though they don't prevent it, at least help to relieve the senile dementia of an old dog, but if it is serious, it may not answer to the medication and the dog would need constant attention.
