I mean if you leave the house early and are out at work all day? This is one of my 87100 reasons for not getting a dog when begged by DCs who are the "only children in the world who don't have a dog".
I leave the house at 7am and I'm back at 5.30pm. Sometimes DH is here all day (shift work), sometimes not.
Do you all walk the dog at 6am before work or when you get home? Do your dogs snooze all day or eat the furniture etc?
How does it work then? :)
