Why does your Cocker Spaniel vomit yellow bile after exercising?

Cocker Spaniels may vomit yellow bile after exercising due to a combination of factors such as an empty stomach, overheating, or excessive excitement. When a dog exercises on an empty stomach, bile can accumulate and lead to irritation, resulting in vomiting. Additionally, vigorous activity can cause stress on the digestive system, prompting the body to expel the bile. If this occurs frequently, it's advisable to consult a veterinarian to rule out any underlying health issues.
