Why is my dog throwing up white?

Why is my dog throwing up white?

The most common reason for a dog to throw up white foam is GI distress. Foamy vomit may occur if a pooch has excess gas in his stomach. If your dog is experiencing indigestion and there’s nothing left in his stomach to expel, he may start throwing up this pale, frothy liquid or foam.

What should I do if my dog is throwing up white foam?

If your dog has vomited white foam only once and is still happy and eating, this may just be a mild upset stomach. Keep them cool and relaxed and withhold food for 12 hours, to help calm their stomach. Monitor them closely for more serious symptoms.
