However, we live in a pretty small house, which we own, and I'm just wondering if it will be possible to have a litter here or not.I think in most cases the space INDOORS matters a lot less than the space available OUTDOORS.(For my breed, my whelping box is 4' x 4' and fits in the living room.) It's more or less impossible (although I do know some people do it and I have the greatest respect for them!) to keep an entire litter of a large breed of pups indoors until 7 or 8 weeks old. They will also need to experience as much as possible and moving outdoors to a good kennel is a good thing, and gives the mother a break too. My pups move outdoors by 4 or 5 weeks of age, which is when they simply CANNOT be confined to a small area any more as they will be active and need to run around and play a lot. (And will also have learned how to climb out of the box!) My first ever litter was accidental so unplanned and although I had the weeks to prepare, I didn't believe it would be a problem to keep them indoors all the time. It was! I'll never forget it, it was a nightmare. I remember one day I brought the video camera out to film the destruction and mess as nobody would believe me otherwise. :)
My pups go out into an 14' x 8' kennel with an attached run which is 14' x 9'. They still need a run around the garden every day though at the age mine are now, which is 6 weeks. (My breed weighs 25-30 kgs as adults.)
(I'm even wondering if I could rent a place short-term to have the litter, then move back here, which is another option, but would be expensive.) I think that is very unlikey to work due to the possible destruction. My indoor only litter completely destroyed my kitchen, down to removing skirting boards, shelves, ripping up the carpet and the plastic tiles AND removing the wallpaper.

There were 9 and far too many to possibly crate or pen.
What is the relationship between dam and litter, as they grow? Should the dam be able to get into the pen and to see them whenever she wants to, but also be able to get away from them whenever she wants to?Here I can only speak from personal experience, and people's experieces (and bitches!) vary -I have seen many people here mention their bitches stay with the pups all the time. I've not been able to. I find for the first few days, the bitch doesn't leave the whelping box at all, having to be carried outside to toilet (and she may have accidents indoors), and fed in the box. For the next couple of weeks she stays close, spending hours in it but also taking breaks having a rest outside the box. By the time the pups start eating solids, she will take less and less of an interest. With my current girl, by 5 weeks of age she will feed them twice a day and that's it. Like I said mine are 6 weeks old today, and if I let mum in to feed them, she will let them suckle for 5 minutes max, then she will start screaming, howling, barking and jumping up into the air, trying to get away from them. (Knowing how much it hurts when they descend on my legs covered by jeans with their teeth and claws, I can imagine how her poor teats must feel!!) So yes, the bitch should be able to go to them whenever she wants, but it is equally important that she can get AWAY from them too.
How much smell does a litter create? When we've picked our pups up from breeders, a couple of breeders have had litters in their large kitchen/dining room areas. I thought they would probably create a lot of smell, but perhaps not if breeders can have litters in their kitchens???Are you sure those people hadn't just moved them indoors for the occasion? Many do. I do myself, simply because it's easier to have somewhere to sit etc, than having to stand outside in a kennel or in the garden. They DO create a lot of smell and they do need a LOT of cleaning. I remember a friend of mine who had a large breed of pups that she kept indoors until 6 weeks. She used to come downstairs in the morning and vomit the first thing she did, as the smell hit her -because they were such big pups (much bigger breed than mine). Of course, the smell is kept at a minimum with careful management, but first thing in the morning for instance it can be bad, and after each meal there will be a lot of poo to clear up, and it is a lot easier away form the house. The bitch will eat all the puppy poo until they are 3-4 weeks odl (again varies in bitches) and during that time it's a lot easier of course.
As I haven't bred a litter, I have no experience of pups 3-6 wks old. What is their daily routine like? Do they sleep a lot?Sleep a lot, play a lot, eat a lot, poo and wee a lot, and also make quite a bit of noise! :) It's like babies. One moment they can be running around playing, the next they all fall asleep in a heap. The older they get, the less they sleep of course and playtimes get longer, but each playtime (such as running aruond in the garden) helps to tire them out. They usually fall asleep after a meal.
As for the noise, hungry pups can create a LOT of noise, and tend to wake you up in the morning not barking but screaming -they're impatient!
Daily rotuine from 3 weeks onwards would involve feeding 4 or 5 times, a lot of cleaning, a lot of playing and handling etc -it does take a lot of time.
Like I say, everyone will have different experiences, these are my own. :) A smaller litter of a smaller breed (I've never had less than 6 pups) would of course generate less mess, need less space etc.
