Nipping just hasn't happened at all here, I am being incredibly lucky with this pup. Oddly, this one does play with toys, Harry just doesn't 'get' toys at all, you guys have mentioned upthread.
We've ditched the crate moose, it's been open anyway for the last two nights and the boys sleep together. No accidents at all from 10pm till 6.15am, but you have to fling him out of the door asap 
No poo's at all in the house and two wee's, both of which our fault, one DH lost the keys for the patio door and two, the tumble dryer repair man arrived, I shut the dogs in the study to greet him and direct him into the utilty etc.
Cardboard boxes are used a lot here, also small pop bottles, with lid on are great fun! Have lots of 'brain' toys too, which I rotate, the spaniel would 'work' for hours, so needs a fair bit of stimulation. Crisp wrappers in socks work well too, supervised obviously but the noise is interesting.
Have just enquired about agility for Harry, and going for a taster in two weeks. The lady who is the trainer has 7 (yes 7) collies, how mad is that!! Oddly, the one she got to Crufts was a puppy when the trainer broke her leg, so all the training she did was done from the sofa. The trainer said she wore him out using his brain, which just shows you doesn't it?
We have lots of soggy toys in the garden too!
Puppy doesn't quite 'get' kongs yet, but I think that comes with age?
