Oh she's a beauty
As to the housetraining.....puppies tend to pee and poop as soon as they wake up, straight after eating and inbetween too

I used to always take my pups outside onto a patch of grass
every half hour, tell them to ''Be Clean'' and within a couple of days they soon cottoned on that going out meant emptying themselves and I then gave them lots of praise and a game

During the night I would set my alarm for 3am and take them out of their crate and take them to their toilet patch, tell them to ''Be Clean'' and as soon as they'd emptied it was back to bed...with no fuss so they realise that Mummy was going to sleep and it was NOT playtime!

Yes, I still got the odd mistake during the day but 99% of these were MY fault because I was too slow and didn't instantly pick puppy up and take her outside as soon as she woke/finished eating etc. It's amazing just HOW quickly puppies learn to let you know when they want to go outside and I'm sure Cookie will soon realise what her new Mummy wants
Yes, it's tiring the first few days and you often think ''WHAT have I done!!!!!!!'' but it soon passes and once Pup is a few months old they don't need the middle of the night loo break.....mine have always snuggled up next to me in bed and don't wake until I do LOL
