My females were
and are a lot harder to train than the males. Just this morning, Gracie wet on my living room floor for NOOOO reason!
She hadn't done that in months. Rebel was fully potty trained at 5 months and have only had 1 episode of marking in the house (he is not neutered and will be 1 year old next month). When I got the doggie door he was 4 months old. He started using it right away and has been WOOOONDERFUL with it. London is A MESS!
Especially here the last week. She's gone back to doing it whenever and wherever she pleases.
