An 8-year-old male neutered Yorkshire terrier was presented for vomiting, anorexic, lethargy, dehydration, and azotemia. A 2 x 2cm dense mass was palpated in the left inguinal region. Non-reducible. R/O renal disease, pancreatitis. Current meds: Cerenia; Famotidine; Ampicillin; Baytril. CBC: pmns 22K; PCV 67%; TP 9.6; Bun 48; Creat 3; Phos 10 (values improving with fluids).

The patient presented for pain in the area of the kidneys, dehydration, and anorexia with increased renal values. The patient initially improved after treatment with I.V. fluids, but the symptoms returned 5 days later. Cerenia, SQ fluids, and buprenorphine were added to the treatment plan. Preliminary blood chemistry revealed BUN 128, creat. 7.6 which improved to a BUN of 29 and a creat. of 2.2; all other parameters were WNL.

A 7-year-old Bernese Mountain Dog (BMD) was presented for a history of persistent weight loss. The only abnormality on physical examination was a thin body condition. CBC and blood chemistry showed monocytosis, elevated creatinine, hypercalcemia, and mild hyperamylasemia. Survey thoracic radiographs showed a 4cm diameter spherical soft tissue opacity mass arising at the ventral tip of the lung to the right of the cardiac apex within the right middle lung lobe. There was also a 14cm x 6cm x 8cm mass infiltrating the ventral portion of the caudal subsegment of the left cranial lung lobe. No pleural effusion was seen.

A 3-year-old male Labrador Retriever dog was presented for anorexia and weight loss. CBC was within normal limits, however blood chemistry showed hyperproteinemia, hypoalbuminemia, low albumin/globulin ratio, marked azotemia, hyperphosphatemia, mild hypocalcemia, hyperkalemia, and hyperamylasemia. T4 was within normal range. The urine had a cloudy appearance; 3+ proteinuria and 3+ hematuria were present on urinalysis.

A 3-year-old intact male Labrador Retriever was presented for anorexia and weight loss. CBC was within normal limits, however blood chemistry showed hyperproteinemia, hypoalbuminemia, low albumin/globulin ratio, marked azotemia, hyperphosphatemia, mild hypocalcemia, hyperkalemia, and hyperamylasemia.

A 13-year-old MN Border Collie was presented for anorexia. Blood chemistry revealed moderate to severe BUN, creatinine and phosphorus with minor ALT, CPK and globulin elevations. Urinalysis revealed isosthenuria was present with a urine PH of 6.0 and some epithelial cells. Clinical dehydration and depression was present. Survey abdominal radiographs and CBC were unreremarkable.

A 10-year-old FS American Eskimo dog was presented for stranguria, hematuria, pollajuria and just not herself. She was non responsive to therapy for UTI. Severe azotemia and moderate anemia developed. Urinalysis revealed proteinuria, elevated WBC, blood and transitional cells, and isosthenuria.
