awww she's still very much a baby.
you need to have a lot of patience with her.
if she's peeing outside sometimes, praise her, make a huge fuss everytime.
don't tell her off or punish her if she has an accident inside.
she'll get the hang of going potty outside in time, but that is the key word. time.
how about making her a little sheltered potty place?
somewhere that she can go without too much wind, snow and rain might make a whole load of difference.
also you can get potty training sticks. they're impregnated with a special smell that'll help Zoey know where she's supposed to go potty.
