Hello this is my first time on this site but I need some answers if possible. My dog has been acting sick since Friday night. He started throwing up and he stopped eating. He's drinking water but throws it up right after he's not hisself all he wants to do is sleep. He seems like he's in pain.. I've been giving him a teaspoon of pedialite every 30 min... I'm taking him to tha vet tomorrow. I just want to know if there's anything else I can do until his apt

There's really nothing more you can do. I would suggest taking him to an animal hospital, or emergency vet. I don't think you should wait until tomorrow.

Good luck.
