Brought Both Of My Poodles Home From Getting Hair Cut

Brought both of my poodles home from getting hair cut yesterday around 4 pm, one of them came in and drank a lot of water and threw it up and had not eaten, and has been using the bath room a lot after drinking water, now she will not eat or drink and keeps trying to use bathroom. tried giving her pipto-bismo and she threw that up, tried giving pedialite and she can't keep anything down.
