Why is my old dog vomiting yellow liquid?

Bile is a fluid produced in the liver and stored in the gallbladder. The bile enters the duodenum (located just past the stomach) to further assist with digestion.

Should I feed my dog after vomiting yellow bile?

If your dog vomits yellow bile just once, there is no need for alarm. Watch your dog for lethargy, diarrhea, loss of appetite, weakness, and other signs of illness. If your dog seems otherwise normal, watch for more vomiting. If the vomiting continues, skip your dog’s next meal and continue to observe.
