Hi there,
we are having some trouble when leaving our 8 month puppy alone in the house.
We have been building it up gradually but today, when me and my mother went out, Kazuki didn't realise that someone was still in the house (my father was in bed) and he was howling. We have been told that he does this whenever he is left alone.
Kaz is a rescue dog after being abandoned by his previous owners when they were evicted. He was left in the house and then found when people came to board the house up. This has led to his problem, and we thought that by showing him we will come back that he will be ok, but the howling continues. Due to our neighbours, it is going to be a problem if Kaz howls all of the time, and we are going to be out of the house for a few hours every day starting January, due to work and college commitments.
I was wondering if anyone has and suggestions as to how we might be able to deal with this as it needs to be quickly resolved.

Thank you in advance for any suggestions.
