TMB, not boasting at all, just a nice reminder/reassurance that it does all come together if you stick with it. 
Sweetkitty, I'm sure it will go fine if you take the introductions steadily and follow GB's advice. Plenty of dogs live really happily with cats and vice versa and it's supposedly easier to sort out with puppies than it is with older dogs.
Butterflies, poor little Luna. Hope she's feeling better soon.
Pip is doing fine. This morning Mum came to sit with him while I did the school run, but she says he didn't even glance at her and set about emptying his two kongs and treat dispensing toy with gusto. (I stuffed his breakfast into them) Mind you, he didn't get his 6.30 am feed in preparation, so was absolutely starving by the time we went out. I put them in his crate with him, so he gets used to that being part of the morning routine.
I got back from taking dd at 9.05 and he was still scoffing without even noticing I'd returned at 9.35, which isn't bad, as I gave them to him at 8.40. So I'm feeling more hopeful about him being quiet for school runs now.
He's also been sleeping a lot more now the dcs aren't here to constantly disturb him, so it's been a quiet day, dog-wise at least, so far.
I am only going to give him a mini feed at 2.00 as well, so he's good and hungry for the afternoon pick-up and will put a nice big feed into his food toys again, although Mum is popping back just in case and will do the same tomorrow.
I'm going to do it a few times over the weekend as well. Just give him kongs etc and pop to the local shop with the dcs or something and then we're going to try leaving him without anyone here on Monday. It's just been impossible to organise leaving him completely alone while all 3 dcs have been home, so fingers crossed this will work.
