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.
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 — it can do more damage than the poison. What we will and won't tell you.
There is no established finding for cats and star fruit — ask your vet rather than assuming it's the same.
No — star fruit should not be given to dogs. If yours has already eaten some, call your vet. 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.
Watch for: Drooling and vomiting; Loss of appetite and lethargy; Tremors; Drinking and urinating more, or straining with little urine. Some signs lag by a day — call, don't wait.
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.
