I agree with Ladylavendar... you gotta lay down the law
Be persistant. My Meka (8 mo) recently regressed a little. Her room is my washroom and its gated...but last month, because she had been doing so well, we thought we'd move her bed upstairs with the family and see how she'd do... Well, the first week she was GREAT! We let her have full run of the house during the day and she was going downstairs to her area to do her business with no problems... Then week no 3, it all went down hill. She started going in other places downstairs when her pad was only a few feet away
Couldnt figure it out... So now we are pretty much starting over...... Good luck to you
