My dog Daisy has had this problem and when she was a pup when she got nervous or stressed out she would start throwing up and it was sometimes yellow or white foam looking. She would not be able to keep anything down, and would stop eating and drinking. Always ending up in the hospital dehydrated. I have had her tested for everything and everything has come back neg.
The only thing that they think was wrong with Daisy is that she has an acid reflex type of thing going on and when she is nervous or stressed it acts up.
What we did was when we knew it was going to be stressful for her....company....holidays....we give her Pepcid ac bf the event. We also took her off of anything with grains in it including treats and dog food....We also only give her distilled spring water to drink. It has made a world of difference in her..
Also when she starts an episode we give her a Pepcid ac and I offer her oranic low sodium chicken broth mixed with water every 2-4 hrs round the clock just to keep fluids in her.
If she keeps that down then I boil boneless chicken breast and white rice and feed her about 4 small meals a day and then slowly bring her back to her dog food.
