Maya is gated off ..... the 1st Floor is free access ...... and you know what she just goes and lays in her crate when we leave .... she sleeps until we get back .....
There will be accidents I am sure .... but maybe you can start with one room at a time .... and reward with treats if it went well ..... mine learned a lot pretty quick ... cause she got her fav. treats ..... we started little by little when she was about 5 to 6 months old .....
Good luck ....
