About Our Hospital

  • They saved my dog's life. They were compassionate and thorough with their explanation of the procedure. My dog had eaten something that obstructed her intestines and needed emergency surgery to extract the foreign object. They took really good care of her and she was back to normal in a couple of weeks.
