Our cocker spaniel, Cooper, is 4-years old. He developed a cough 3 weeks ago. He was throwing up a bit. But otherwise, perky, eating, going potty fine. Took home to the vet, received antibiotics and cough syrup. Two days later seemed worse. Took him back, blood work was done, ex rays of thorax and lungs. X-rays were clear. Blood work was not. Creatinine was 6.0, BUN 133, amalayse 2244, albumin 2.6. Trip to hospital, Exrays, ultrasound, IV fluids with no improvement. Creatinine went from 6.0 to 7.1 in 5 days. Creatinine now up to 8.0 on day 8. All the usual meds are being given, Cooper will not eat - neither his kidney diet nor his favorites and won't even touch the homemade recipes I've found here. He is just lying around. It's so sad....what should I expect? What can I do?
