thanks ladies...will let you know what happens but I do notice a lessening in the odour so perhaps it will improve on it own:(

I used to think he was piddling in the house because he missed Vern but now I think he is just being naughty as it is nearly 5 months since Vern passed.

I just cant leave him outside at night as he would drive the neighbours mad with his barking and for sure I couldnt lock him in the shed so it looksa as tho Im going to have to just keep my eyes open a bit better :*(
