Hey DD ... not to worry my sis & i rented a huge house years ago & yeh, it too stunk of dog smell BUT once the owner got it steamed cleaner after a few weeks the smell went (before we moved in i might add) ... YOU might need to still open the windows on a daily basis for a couple of weeks (maybe for peace of mind) !!

This house i live in now that DP & i purchased 4 years ago smelt of cats ... yes cats ... and poor DP is allegic to cats to top it off ...so the previous owners got the carpets cleaned before we moved in and it worked a treat (BUT forgot to check for cats hairs attached to the drapes so i went on a cleaning frenzy when i moved in)
