Thank you guys. Giselle did well. The procedure took about 2 hours and I picked her up at 1 AM last night. What surprised me most is how much stitching the vet had to do, but, like Cindy mentioned, I think most of it is just due to Giselle's thin greyhound skin.

Here's a pic of her injuries (warning: it's pretty graphical)





Ivy seems to know that Gis is injured. She tried initiating play with Giselle but then sort of sniffed her, wagged her tail, and walked away. My parents aren't too happy with Ivy but we are all keeping a very close eye on her now. She now eats in a closed crate and is crated when we are away (no more roaming around in the dog room with Giselle). I know it's just a dog thing, but it's just disappointing when scuffles turn into something like this
