I just called the vet's office, and the vet I saw was not in the office today. I left a message with the desk to have her call me tomorrow after hours. We will see. I am just killing myself trying to think of things I could have done differently. Maybe the water was too deep and it freaked him out...though it was just covering his back legs- all he had to do was hold his head up instead he shoved it down level to his front feet. It was a little deeper than his water bowl (which he freaked out in earlier that day) to cover his back legs, but not deep. I am just sad.
