[case.gif] Case summary
A 12-year old chow had a history of hepatitis, associated with anaemia. It was noted that the dog vomited frequently; its general condition gradually deteriorated, leading to its death.
The animal regularly ate lantana and the post-mortem revealed 3-4 litres of liquid vegetable matter in its small intestine.
