Every time I leave my dog outside our local shop for 3-5 minutes to buy a bottle of milk etc, he barks incessantly. He can even see me while he's barking, it doesn't matter... he knows where I am, he just doesn't like being left for any period. He's fine to be left at home.
I really wish he would chill. What should I do? I was thinking of giving him a chewy treat next time...
Anyone have this issue?
