This seems more likely to be due to regurgitation rather than vomiting. Commonly, megaesophagus (pathological enlargement of the esophagus) is suspected in these cases and possible differentials have to be ruled out to establish a diagnosis. Neuromuscular disease (e.g., myasthenia gravis, distemper, myositis), esophageal masses, Toxicity (e.g., lead, thallium), idiopathic inflammation of esophagus are all possible. A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed.
