Mainly the toilet training - she just doesn't seem to be getting it. Several times, I've been outside with her for ages and she'll actually come inside and pee on the floor. It's our fault because we tend to have the bi fold doors open a lot when it's nice weather so she must be confused. We're starting to use the lead when we take her outside now and just stand in the bit she usually uses to see if that helps.
Also, we've tried to take her out in the car a few times (short journeys) and she poos every time. We have her in a fabric crate thing my MIL lent us.
The one saving grace is that she sleeps brilliantly. Takes herself off to her crate about 10pm and sleeps through til someone goes in at 7 or so.
(Doesn't help that I just got my period and have the most appalling peri-meno PMT)
