Leaving a puppy at home

[heidiwine]

Help!
We are going to pick up our pup in a couple of weeks. Five days after he arrives I have to go to an all day conference and will be out the house from 8:30-6:00. This is v unusual for me and I have no option but to go.
DP is going to work from home from 1:00.
So the puppy won't have either of us there from 8:30-1:00. Help - these are my options:

1. leave him alone
2. arrange for a friend/neighbour to stop by for half an hour a couple of times
3. arrange for someone to actually be in the house for most of the time.

What's the best thing to do?

nah, just bio laundry powder or liquid will do the same thing....
