Even though I hope no one ever has to go here, I will share our experience.
Our little girl was diagnosed with sudden onset IMHA by our regular vet. He said to get her here as soon as possible, which e did. It took two weeks and was very expensive, but they saved her life. They were receptive to us calling and let us stop by to see her as often as we wanted when she was awake. It was such a traumatic experience but the staff here was so great.
More importantly, the doctors here know what they are doing. To the point my vet deferred to them completely about what the plan of action was going to be. They told us the options and didn't let us give up hope, even when things were really, really bad.
...and in the end, we had a win for the home team. With a happy healthy chunky little Shi-Tzu girl.
