As suggested on here and by our trainer, we've taught 'bark' today. Now I'm terrified he won't learn 'quiet' so quickly! I'm bathing DD and can hear him barking outrageously at DH. I'm sure it's okay - maybe he's practising 'quiet' as well. We're saying 'enough' actually. I did ask DH to practise, now I'm regretting it I think!
