After much um-ing and ah-ing I decided to bring her home. She didn't seem responsive to me when I got there, but she is eating now (ravenous actually) and walking a little more steadily.
ER vet said I could take her, or they could monitor for another 24-hrs as she was still on a drip. The clincher was, when they took her out the back again she barked her little snout off. So I knew she was ready to come home.
Poor ER vets and nurses had been so busy none of them had lunch. So it was funny to have all these people come out from the back at the smell of Tully's tuna patties.
Got to give her behind a good wash as she's quite stinky. Then I'll set up the larger crate so she can get away from the puppy..
Unfortunately when I got home there were 2 pees to clean up (puppy gets way too distracted outside), and a big pile of vomit in the kitchen. I was only gone 2hrs!
