Electricity

I had to get an electric fence for Claude.  Someone found him in the street a ways away, recently that was the final straw.  I knew he would run off for an hour every day, but I thought he was safe, hunting in the acres of open land behind my house.  We enclosed large area for him, a few acres at a minimum, but still I feel a little bit sad for him since he loves to run far and wide and fast with those long legs of his.  ...... but better alive than dead.  I know that.

I'm wondering if it's normal for a dog in training to seem a little depressed?  Today after 2 weeks of it, he seemed a little bit happier, the day was full of light, and bloom, but still not his entirely exuberant self.   I'm hoping in time, he will be ok with it, or if the lust to roam always remains.
