Why Is My Dog Throwing Up Yellow Bile

Should I go to the emergency vet?

Go now if the bile vomiting becomes repeated retching with a swollen belly, or if there is blood, collapse, or a possible toxin. One morning bile episode in a bright dog that then eats can be described at a prompt appointment. A deep-chested dog that cannot settle should leave for the clinic.

How much will treatment cost?

Yellow bile in the morning, in a dog that then eats and acts well, still deserves an exam if it happens most days. The clinic looks for an empty-stomach pattern versus pancreatitis, a foreign body, or bilious vomiting syndrome. Bloodwork and a diet plan are the usual costs.

Can I treat this at home?

Note the time of day and whether the dog ate dinner. Ask the clinic before you add a bedtime snack. Repeated vomiting, blood, or a painful belly means go in.
