Can a dog die from eating packet of the stuff they put in shoe boxes?

No, dogs can't die from eating the packets that are often found in shoe boxes. These anti-moisture sachets are filled with a substance called silica gel, which is a desiccant—a material that absorbs moisture from its surroundings.

Dogs may experience tummy upset (ie, vomiting or diarrhoea) if they consume the silica gel packs, but they are not dangerous and rarely cause any lasting harm to dogs. If your dog has eaten one of these packets, keep an eye on them for any signs of illness, but veterinary attention is usually not necessary.
