Case 2:
Signalment:
Dog. This was a geriatric (12 y.o.) cattle dog. Euthanased
because of dehydration and weight loss consistent with renal failure.
Clinical signs:
The dog had been drinking more (polydipsic) and urinating more (polyuric)
for some time and had shown progressive weight loss over the past 2 months.
Urinalysis revealed proteinuria and isosthenuria (urine specific gravity
equal to that of blood plasma, ie 1.008 -1.012) despite dehydration. Serum
biochemistry revealed markedly elevated urea and creatinine levels.
Other information:
Animals use the kidneys to excrete electrolytes and waste products.
The ability to concentrate urine when the body is deprived of water is
essential to preserve life.
