My pups were 3 weeks old on Wednesday and doing really well. To be honest now they are bigger, my girl is finding them really daunting, there are 10 of them and they are quite a size and mostly only goes in with them if we encourage her and sit in with her. They have started weaning and with our help are getting there.
My question is, when do you all bring them out of the whelping room into the rest of the house. There next area will be in our kitchen where we can give them more space and see more. It is a bit cold in our conservatory where we will move them again at about 5-6 weeks so they can start exploring outside as well.

Of course everyone keeps their pups in different areas, but personally mine are raised in the lounge so they are used to the sights and sounds from when their eyes and ears open.  From 4 weeks, if the weather is good enough, I put them outside for short periods and also spend periods in the kitchen with me.

I can't do that because of my other dogs. I have a real problem with one of my others who will just jump in if you leave the pen available for Mum to run in
and out.
Also I believe that Mum is entitled and needs  privacy in the first couple of weeks at least. Because the room where they are is next to our work room - we have barely seen our living room since they were born so they have seen more goings on than they would have done in another room.
If I put mine outside in the weather we have now they would just curl up and shiver so I don't plan on doing that yet.

I start bringing mine through when mum is happy for them to be moved. They still sleep at night in the spare room but in the day time spend more and more time with the family in the rest of the house. I have photos of them sleeping behind chairs, the sofa, on the other dog's beds.

Our puppies, Bassets, which are not small, were (back here in the UK) in a 4 X 4 whelping box in the living room where one of us could camp on the sofa with them overnight.   Once weaning started and they were up on their little legs, we moved the 4 X 4 box into the kitchen and added the second 4 X 4 section to it to give everybody a bit more room, without having them running around the house, under the feet of the rest of the 'pack' which wasn't advisable for any number of reasons.   And as most of our litters were planned to be into the 'better weather', if the weather was mild enough, we had them outside for short periods of time in an extended ex-pen to get some sun on their backs, and give me a chance to do a good clean out of the box!!

By the time we started weaning (around the end of week 3 going into week 4) mum certainly wasn't in with them other than to clean up after them, and initially to allow 'comfort suckling', usually standing up and once the nipping started, out - fast!!  Ouch.    10 would certainly be 'daunting'!!   So good luck with the work that lies ahead for you.....  I always loved the first 3 weeks or so, provided mum was up to her job.

Have fun - you'll be really mixed up by the time they all go home - part loving it all and part PHEW!!

Between two and three weeks.

Used to be two weeks until I had one bitch who was more guardy with pups with the other  dogs and found by three weeks she was really relaxed, so now do it at three weeks as, pups are in living-room these days from birth and not a bedroom for first two weeks, as in the past when I had young children at home.

I can't do that because of my other dogs. I have a real problem with one of my others who will just jump in if you leave the pen available for Mum to run in
and out.

Don't quite understand why that is a problem? My pups are 3 weeks and all the other dogs visit them now, it's part of their socialisation, and mum definitely doesn't mind at this stage. :) Have done this with every litter, the exception is when I have toypups as then I cannot risk a great big dog stepping on a tiny pup, so then they are in a puppy pen and visits with bigger dogs are supervised.

Ditto, I move the pups in with the other dogs at three weeks, (the other dogs aren't allowed in the livingroom where pups are before that) though two weeks in the past was fine for many fo my Mums, but noticed that the other dogs tended not to want to visit in with them until around three weeks.

The dogs have been able to go up to the run for the last week so the pups have seen the others ( although my eldest 2 try and pretend they are not there ) but I have to close it as I have two that will jump in, one of which would let the pups come up to her but when they try to feed she would go for them, guaranteed. It is OK for Mum to do that ( and I wish she would as she is not disciplining them, I am )
but I do not feel it right for this to be one of the other dogs. So when Mum needs or wants to go in we have to 2nd guess and open the pen. b
I moved them too early once before ( about 3 weeks ) and a Mum that had been very happy to be with her pups, no longer did. They are 4 weeks on Wednesday and we are moving them to-day into a bigger run in the kitchen.
There is no way I am afraid I could allow them to be free as they would be floored, not a good thing in a terrier breed.

When my bitch let the other dogs in to see the pups it was actually her younger brother that took over the parenting (apart from the feeding of course ;-) ) He would play with the pups all day if I let him :-) Mum just supervised from a distance. He was more devastated than she was when they eventually all left to go to their new homes. I always go with mum. If she allows the others in then it's ok, so long as I am there to watch over them.
