Why would you be open until 10pm and not have a vet on staff!! I brought my dog in who was throwing up some blood at 7:30p and they had to refer me to the the emergency vet. I'm sorry that we couldn't come when it was more convenient for your office hours. I highly advise you change your hours or post it EVERYWHERE that unless it's before 6p, chances are your animal won't be seen. I just hope my dog is okay or it's going to be really hard for me not to blame you.
