Dogsregurgitates In The Morning. If you notice that your dog throws up nearly every morning, there is likely some sort of gastrointestinal disturbance or issue that is causing him to experience this problem. It’s why we often worry when our dogs throw up.
The whole dog journal states that dogs often vomit when their stomachs are empty for too long, and the stomach bile has likely caused irritation. But you shouldn’t be too worried. If this occurs anything the dog drinks or eats can get stuck in the weak part of the esophagus and pool there until the dog regurgitates and spits it back up.
