Can rusted metal hurt a dog?

Rust (iron oxide) itself is generally considered non-toxic to both dogs and humans if ingested in small amounts.

But if ingested in larger quantities, which is possible as dogs sometimes like to chew on metal, it can cause gastrointestinal issues such as vomiting, diarrhea, and abdominal pain.

It is important to monitor your dog's consumption of any non-food items and to seek veterinary assistance immediately if symptoms occur or your dog appears unwell after consuming rusted metal.
