Quick update...

The vet called at noon. Kayleigh has a large laceration under her tongue. At least some of the blood is coming from there. She will have to be knocked out to get some stitches. The vet is "on the fence" about an exploratory surgery. She has no obviously painful spots in her abdomen, but she's stoic by nature. Her pain tolerance is quite high. Her stool is tarry, which indicates blood in her digestive tract, but it's hard to tell from the outside if the blood is coming from an internal problem or if it's blood she's swallowed from the cut in her mouth. So while she's knocked out, they are going to do some x-rays of her abdomen, maybe an ultrasound and bloodwork. If any of those things show abnormalities, they will have to do the surgery to see what's going on internally.
