This is so on the mark. I have watched almost every episode of this guy on the National Geographic Channel.
He would say to you about this chewing dog.
1) This dog has been pent up for weeks and is a frustraited little beast. He needs to get his mind in focus and that means WALKS. His fix would be to have the dog take walks with you for an hour a day holding the dog just behind your step while walking so as to let the dog know you are the pack leader.
2) Your vibe or attitude is picked up by the beast at all time so project quiet calm and love while dealing with this little spirit of dog-dom. You got this dog to spend time with it and so now your responsibility starts.
3) NO rewards of love or food when the dog is doing the not so good chewing on shoes.
4) When the dog goes for a off limits chew... replace that item saying simply NO in a firm voice with a good chew item given the dog to replace the off limits item and a mesured time later when the dog is chewing the good substitue and getting into it big time... THEN GIVE the dog PRAISE.
5) My observation with dogs is that under the neck on the chest is the one place they can't touch themselves. For special praise this area can be rubbed and saying in a deep low voice "Good Dog, Good Dog" will reinforce good behavior with amazing results.
Hope this helps
