My sweet 14 year old Pomeranian
had an episode of Congestive Heart Failure 2 weeks ago. He was treated successfully and responded well to the Lasix, etc. However, when he had his follow-up work a few days later, his kidney levels were bad - over 11 phosphorus, high BUN and creatinine. We took him to the hospital for hydration and the BUN came down to 87, creatinine a little above normal. On follow up a couple days later his BUN was 140, creatinine 2.8, and phosphorus normal.
