- Despite the name, choke is not a primary airway obstruction
Most cases are caused by feed impaction
Common clinical signs include hypersalivation, food-contaminated nasal discharge, attempting to swallow and dysphagia
Diagnosis is based on clinical signs and confirmed with nasogastric intubation or endoscopy
Most cases resolve with sedation and oesophageal lavage, but surgery may be required in severe cases
Proper dental care, feeding practices and management of underlying conditions are all key for prevention
