A 15-year-old SF DSH was presented for evaluation of walking hunched in the back legs, PuPd, and decreased appetite. On physical examination, dental disease, mild heart murmur, and a mass in her mammary chain were present. Urinalysis showed specific gravity of 1.019 and proteinuria. Abnormalities on blood work were mild hyperglobulinemia and hypokalemia. A cursory in-house ultrasound revealed a mass near the left kidney.
