Hi Sarah and Paul
I thought you would like an update on Mac, unfortunately he still barks when left alone but I'm not sure it is all the time as he is quite when we leave and when we return. He is good most of the time when meeting a dog for the first time he seems to reflect he other dog if they are unsure then he is unsure.
However he does have a problem with the dark, he is easily spooked when out in the dark which results in him staying on lead as he would run off but he will not go to the toilet when on lead. When it is dark he will not move away from the door the result being is that he messes indoors every night taking him out late at night has stopped him weeing over the last few nights have you any ideas what we could do next.
Hope you have a great Christmas
