I have two shih tzu's (dog Oscar and bitch Molly). They sleep in the conservatory of the bungalow we've lived in for about 18 months. The past few months Molly just won't settle when its bedtime. A few minutes after I've shut them in she just barks and scrapes at the internal door. I go in, smack her nose and tell her no but have to do this at least 3 time until she settles. Anyone have any ideas? I've tried leaving light on, giving her plenty of attention through the evening but nothing. The other dog is good as gold. Lukily ds (11 months and sleeping in next room) hasn't so far been woken by her barking but it's driving me mad! Have I got to do controlled barking with her???!!!! PLEASE help if you can.
