I have a little mixed breed dog. He isn't quite a year old. He isn't eating or drinking but keeps vomiting clear liquid. I don't know what to do.

Definitely needs to see the vet first thing. It could be something simple or something life-threatening and you need to find out ASAP.

See your vet! I had a dog who had this problem and died because we were too late. Good luck! See the vet today!
