Are Dogs lacking something in there diet if they eat wires?

No, eating wires is not a sign of a dietary deficiency. Dogs eat wires for a variety of reasons, including curiosity, boredom, and pica (an eating disorder in which animals consume non-food items). Eating wires can be dangerous for dogs, as it can lead to punctures, lacerations, and electrical shocks. If you think your dog has eaten a wire, please contact your veterinarian immediately.
