HGE - please help!

[minpinowner]

Hi:
My 5 year old min pin is suspected to have HGE. He has been having very bloody diarrhea for the past day. I took him to the vet this morning, where he still is now, hooked up to an IV (including receiving 150ccs of Bolus). My vet 's office is not a 24 hour care center. However, he has told me that he checks the dog prior to leaving for the night and if doing okay, he does not recommend that the dog be transferred to a 24 hour facility. I, however, am nervous about my dog being left alone at night. What if he takes a turn for the worse and there's no one there to discover that? So my question is whether I should have him transferred to a 24 hour hospital. It will be more expensive, though I'm not so concerned about that as I am about him (1) enduring the transfer (during which he will not be hooked up to an IV, I assume) and (2) being in a bigger hospital with potentially more chaos and less individualized attention. Any thoughts on whether to leave him at the vet or transfer to a 24 hour facility, please?
