My 2 1/2 yr old yellow lab has had crystals more often than not. My vet put her on Hill Science Diet C/D. She was on Natural Balance Liminted ingredient before the C/D. Currently she's getting the C/D as her food and Im using it as a treat. She's had two months so far crystal free. I want to start her on a new diet and someone recommended Abady. Has anyone had any experience with Abady and crystals?
