I was told when I brought my dog in for his dental and surgery at 8 am that someone would be contacting me when he woke up from surgery and would let me know when to pick him up. I did not receive a phone call and finally at 4 pm I finally called, thinking something was terribly wrong if my dog hadn't wakened up yet!!!
The receptionist told me that he was very much awake and I could come and get him right away.
I would have appreciated a call!!! It would have saved me much worrying about him!!
