I've had Oscar for a week and he is 9 weeks old. He barks when i go out. I've tried leaving treats in his crate before i go aout and taking it in short spaces of time. I started with a minute and worked up. I just wait around the corner and he nearly always starts barking when he realises i'm not in the room. The only time he doesn't bark is if he's a sleep whilst i'm out. I know its early days but I'm worried he may continue to do this when i eturn to work in a couple of weeks. He is a Hungarian Vizsla and he is my first dog. Other than that he is perfect.
