Thanks everyone for all of the thoughts & prayers! Much appreciated
Update: I was going to go pick Dexter up, but the vet receptionist called to inform me that Dexter's pick up time changed from 2:30 to 5:00 pm. The receptionist didn't have much of an explanation for the two and a half hour time difference, but she reassured me that Dexter was doing perfectly fine and the procedure went really well.
I'm assuming that they are just wanting the anesthesia to wear off more? Anyways ... Clyde & I can't wait for Dex to come back home already LOL
