Sudden deaths in greyhounds due to canine haemorrhagic pneumonia

We wish to draw fellow practitioners’ attention to this uncommon disease. In about 50% of cases Streptococcus equi zooepidemicus can be isolated. The infection is characterized by a sudden onset lethargy, pyrexia (above 39.5 ̊C / 103.1 ̊F), and tachypnoea. Coughing is not a consistent sign and its absence should not prevent the consideration of pulmonary disease, since CHP is a pneumonia, not a bronchopneumonia. A haemorrhagic oro-nasal discharge is seen as a terminal event.
