Thanks for all the immediate attention and support. Much appreciated!
Ava is sleeping now, finally. I'm taking that as a good sign. She is stretched out instead of curling in a ball.
Heidigsd and Bowow -- I'll keep HGE and the test on my list of things to bring up with my vet
Harmony -- agree with keeping them hydrated. I've been using a small turkey baster to get some liquids in her system.
Kiya -- no globs of blood here, thankfully. That sounds scary as well. Ava has been shooting red tinted light brown water. I think she went 4-5x since 7:30 am including this morning red/brown water stool. No solids. Just liquid.
Send some positive thoughts Ava's way if you have a moment!
