Serving advice
Treat Water chestnut as a snack rather than part of the daily ration — the usual ceiling is about 10% of daily calories. Start with one small piece of Water chestnut and watch stools and appetite over the next 24 hours.
Peeled and sliced, raw or cooked.
Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.
There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.

Why these cautions matter
Raw animal protein carries Salmonella and E. coli risk, and those bacteria can spread to the people in the household too.
