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

Wire if swallowed can puncture the stomach and intestine in which case you need to take it to the vet. Dogs will eat a ton of things they're not meant to. It can be that they just like to chew things. On the other hand it could be an indicator that there is something essential missing from their diet. My husky was constantly licking the hinges on my doors inside the house, a sign she was lacking in vitamin B complex. Supplimenting her diet with dog vitamins has stopped it.
