Sick Dog- Worried - update

Daisy has been throwing up, having diarrhea it now has blood in it. The vet opens at 10:00. She is acting like herself but I am worried.

Update: went to the vet and he said it is a bacterial infection and probably picked it up on a walk. Gave her two shots and antibiotics. She is not dehydrated so she didn't have to stay. He said no food or water for 24 hours. She was jumping around the vet like a nut. Now she is walking around the house and won't lay down. I think she has some anxiety from the vet and the car.
