I know how you feel- I had to leave Banjo all nite after leg surgery-they did say 1 student was there all night!!
I kind of thought for how many dogs(Vet School) and I figured they slept or studied all nite, too!
I would rather he had been w/ me!
Try and get some sleep, so you can take really good care of her tomorrow!!
Hugs to you and baby!!
