laminitis is the bigger issue, not colic...which she would have needed Charcoal tubed in her hours ago. I'd keep trying to get up with the owner, and BO...the BO should have some type of emergency contact, plus ideally a release to call the vet if teh owner can't be reached.

I know I make my boarders sign a release that I can call the vet at my own discretion if I can't get a hold of the owner, and I'm authorized to incur up to x amount of vet bills.
