CLINICAL SIGNS

• Clinical signs depend on the degree of distension but the usual signs are a diffuse, painless, elastic tympanic swelling in the parotid region.
• It may extend downwards and backwards towards the throat and upper part of the jugular furrow. If markedly affected, the foal may exhibit stertorous breathing, nasal discharge, Dysphagia, respiratory distress or evidence of pneumonia secondary to aspiration.
•  Pressure on the pouch may cause some of the air or gas to escape with a whistling sound.
