Daisy, something crazy with the site as PMing not working-just flicks me back to the top of the thread 
You're quite right, Our ginger pup is from working stock, on dad's side anyway, though a bit on mum's side back down the line, though the breeders are a family with young teenagers, a couple of labs, a westie(which pup does not like) Breeders do a lot of training with mum though, doing agility work etc. There are a long list of field trial champions on dad's side going back generations. Will keep trying with pm so you can check them out. I think sire was picked as stud as he is such a healthy prime dog-tested for everything within an inch of his life-even DNA tested for narcolepsy!!!
Alp, our behaviourist said NOT to do the pinning to the ground thing. Wags above who has a bit of a devil dog like I have, though is a guide dog pup
. She and behaviourist both said that pup to always have a lead on that you can grab if you need to, and give a gentle tug along with a No Biting. Also to hold them gently away from you on the floor, and if they don't settle then tether them to a radiator...
Devil pup, remains devilish. Am deliberately keeping her day very calm and boring, only doing training and brain training in the garden. She's a monkey though and just gives me no peace! Settle dog, settle! And stop biting me!
