Dog Constantly Swallowing at Night? 9 Causes and When to Worry
A dog that keeps swallowing, gulping and licking its lips is most often nauseous, but reflux and esophagitis, a stuck bone or chew, mouth or throat pain, nose and airway problems, megaesophagus and swallowing disorders look similar. Night-time episodes fit reflux (restlessness at night) and empty-stomach nausea in the early morning, yet timing alone proves nothing. Go to a vet now for unproductive retching with a swelling belly, breathing trouble or bluish gums, or drooling with an inability to swallow; a stuck object should be removed immediately once diagnosed.
