Slightly risky. Wilted chard is safe if not moldy, but its oxalate content concentrates as it dehydrates. A small bite may cause mouth irritation or mild stomach upset. Remove any slimy parts and rinse well before offering. If your dog ate a large portion of aged chard, watch for excessive drooling or lethargy and call your vet if those appear.
