What is Dog Bile

Dog bile, also known as bile vomiting syndrome or bilious vomiting syndrome, is a condition that can affect dogs. It is characterized by the regurgitation of bile, which is a yellowish-green fluid that is produced in the liver and stored in the gallbladder. This condition can occur in dogs of any age, but it is more common in middle-aged or older dogs.

The Main Causes of Your Dog Vomiting Bile

1. Gastritis

Gastritis, or inflammation of the stomach lining, is a common cause of a dog vomiting bile. This condition can occur when your dog eats something that doesn’t agree with their stomach, like garbage, spoiled food, or an inedible object. Overeating or eating too quickly can also lead to gastritis.
