A small amount of star fruit is generally low risk for healthy dogs, but its oxalate content is a real concern for dogs with existing kidney issues.
Star fruit contains a notable level of oxalic acid and, separately, a neurotoxin that's a specific concern in dogs and humans with impaired kidney function, where it hasn't been effectively cleared from the body. For dogs with healthy kidneys, small amounts are a lower risk; for dogs with known kidney disease, star fruit is best avoided.
