- Don't make your dog vomit unless a vet tells you to.
Signs to watch for
- Vomiting

- Trembling
- Increased thirst and urination

Why
Soluble oxalates bind calcium in the body and can damage the kidneys. Sweet star fruit is not considered poisonous to pets with healthy kidneys. Bilimbi (belimbing buluh), a sour relative, is also very high in oxalate and has injured people's kidneys.
