Whilst teething, watch any electrical extention cables you might have. Found my Jack Russell happily gnawing through an extension cable my PC was plugged into.
We gave her one of my dads old belts in the end to get through it. It pretty much gnawed away the whole damn thing, barring the buckle.
Already chewed the wire to the pump to our pet fountain after being confined to the kitchen on her first day without mom and dad. Then chewed phone line after digging it up while digging at carpet by the door on the next attempt. New pump on the way and new phone line already installed taking new non-chewable path. Other wires already protected because of cat who chews wires but doesn't know how to chew her food.
