Teddy is a 5 year old collie who is owned by a veterinary cardiologist. He developed acute kidney failure and jaundice and was hospitalized at her practice. Over the course of the next few days, he did not respond to standard treatments, and his urine output started to decrease to a dangerous point. He was transferred to us for dialysis. We started treatment, and at the end of the first treatment, his urine production was improving. We treated him a second time the next day, and he was definitely feeling much better. He started eating, was strong enough to walk without support, and started to wag his tail and greet other dogs when they walked past his cage. His urine output continued to increase and his kidney function started to improve. Since he no longer needed dialysis, he was transferred back to his regular clinic to be closer to family during his recovery. He had an infection called leptospirosis and went on to have a full recovery.
