The clinical signs of GDV are usually '''acute in onset''' and may follow a period of exercise and/or feeding of a large meal. Affected dogs typically display '''non-productive vomiting and abdominal distension'''. Acute onset restlessness, abdominal pain, hypersalivation and abdominal tympany are other common features of GDV. On physical examination, the dog may be collapsed or reluctant to stand. Signs of cardiovascular '''shock''' may be present including tachycardia, pale mucous membranes, prolonged capillary refill time and poor peripheral pulses. An irregular heart rate combined with pulse deficits indicates the presence of [[Category:Arrhythmia|cardiac arrhythmias]].
