Bile is a fluid produced in the liver and stored in the gallbladder. The bile enters the duodenum (just behind the stomach) to further aid in digestion. When dogs vomit yellow liquid, the stomach may simply be empty. Stomach acid irritates the stomach lining and causes the dog to vomit.
Dogs sometimes vomit yellow foam. This yellow foam is a form of bile, or digestive fluid, produced in the liver, stored in the gallbladder, and released into the small intestine just below the stomach. This yellow foam usually means their stomach is empty and the bile is causing stomach irritation.
A dog vomiting yellow foam or bile at night or in the morning can often be caused by an empty stomach. A lack of food can cause bile to build up and irritate your dog’s stomach lining. So in this case, it’s a good idea to feed your dog after you see him vomit yellow.

You can try feeding her a bland diet mix of cooked white chicken and cooked white rice for two to three days and see if that helps settle her stomach. If she continues to vomit or becomes lethargic, she should see your vet immediately.
Let your dog’s stomach rest
Resting the digestive tract is important when your dog is vomiting. I usually recommend withholding food for at least six to eight hours (don’t fast puppies though). Depending on the situation, you can also try herbs, a homeopathic remedy like Nux vomica, or small amounts of bone broth.
