Why is my dog pucking up saliva?

If your dog is puking up saliva, it could be due to various reasons, such as nausea, an empty stomach, or gastrointestinal issues. Excessive drooling and salivation can also indicate anxiety, dental problems, or the ingestion of something harmful. It's essential to monitor your dog for any additional symptoms and consult with a veterinarian to determine the underlying cause and appropriate treatment.
