Thank you for all your replies I'll try to address what I can...
I now know that sprocker isn't an actual breed! She remains unregistered 
She is crate and toilet trained thankfully, was bought from a gunner who I'd spoken to (why we were set on having her) our crate should be here soon but she's been happy enough on a dog bed so far downstairs. Thank you sex, I've got a Kong on order and will add those to my next delivery! I've not looked at the vids yet it's on my to do!
Lettuce she is high energy, has a crazy streak and loves rough and tumble and cuddles. She's also very clumsy and just adorable, she needs a firm hand (as in boundaries, she's gets a little carried away at times and nips, she's obviously teething) we have about a weeks worth of the food she's on since weening thanks to the breeder!
Pig, we trust the opinions we had at the time, they were spot on it seems!
Our intended trainer is exactly what you describe, we start in September but have a lot to be starting her on in 5 min intervals to keep it fun. She's already got a better recall than I'd imagined and dc taught her the game of catch. Very proud of all my babies!!
We've kept her downstairs, she seems fine with this and sleeps with the tshirts one of us has worn that day (my idea, seems to keep her calm there's only been a little crying today when I kept her away from the kids eating) I'll look at a harness thank you!
Shizzle, she seems to be a mix of both! Like a loon outside most of the day and asleep on the dc the rest of the time! She's in the vets end of the week so hopeful we won't be in too much longer.
Thank you so much for every bit of advice! To give an update we met her and the kids adored her, she was excitable and still is, but we brought her home and she's been fab. Come out of her shell today and can see she's high energy but equally loves lay lazing on me or dh at night, has been nipping today but a firm no and being ignored for a minute or so has been working. Have some training techniques in mind for next few days, she's highly food motivated and have I mentioned she's lovely!
She was actually a dream the first two days, she has us all figured out now though. Today has been a little challenging but in all fairness it's not all down to her. She has a lovely temperament and I'm keen to let her be a puppy but with firm boundaries, I really need to get watching those recommended YouTube videos! Thank you again, currently lay with the little one who completed our family and although a few hours earlier I was wondering on my sanity I couldn't be more sure that she's a perfect fit.
Excited about all the walks and trips we have planned! Just a little question, is the crate suitable for popping her in for an hour on the road to wherever we are going? Or should we add bars for the boot of the car? Want to keep the crate a positive and safe place, not a 'trapped' and scary experience!
Re insurance, I'm due to get her medical (she hasn't had one yet) and was going to get insurance after as assuming no jabs would be more expensive, anyone recommend a policy? Pet plan were my intended choice but £45 a month is steep for us!
