Why
Star fruit is high in soluble oxalates, which can bind calcium and damage the kidneys. Vets treat it as one of the fruits to keep away from dogs entirely rather than a moderation food.
Signs to watch for if your dog has eaten star fruit
Drooling and vomiting
Loss of appetite and lethargy
Tremors
Drinking and urinating more, or straining with little urine
Signs vary with the amount and with the individual pet, and some appear only after a day or more. Their absence does not mean your dog is in the clear — call rather than watch.
What to do now
Don't feed it. If your dog has already eaten some, call your vet or poison control with the amount and the timing and follow their advice.
Never induce vomiting and never give any medicine unless a vet tells you to. With some substances it causes more damage than the poison. This page tells you when to get help — it never tells you how to treat at home.
Safer alternatives for dogs
Plain baby carrots or carrot sticks
Plain cooked chicken breast — no skin, no bones, no seasoning
A few blueberries or a slice of apple with the core removed
Plain canned pumpkin (not pie filling)
Plain green beans, fresh or frozen
What about cats?
There is no established finding for cats and star fruit — ask your vet rather than assuming it's the same.
Verdicts are transcribed from the cited veterinary sources, never inferred. Where a source establishes a finding for one species only, the other species is left null and the page says to ask your vet — a dog finding is never copied onto a cat.

More than a taste can cause real illness, and the risk rises with the amount and with a smaller pet. The safe amount is none — if your dog has had more, call your vet.
