I have a 2 week old litter of pups who with mum have been separated from the other adults in the house and I'm  wondering how long everyone keeps other adults separated from mum and pups?

I usually wait until they have eyes open and can stand on their own then allow the others into the room, although they are separated with a room divider.

I just feel sorry for the others kept out of the main living area and in the very small kitchen!

for my very first liter my living arrangements meant the bitch had to have her litter in the area where myself and the other dogs spent most of our time. the other dogs were kept out while she actually whelped but after that everyone went back to their normal routine. Mum didn't mind the other dogs near her puppies thankfully.
These days I have pups up in my bedroom so I can keep the other dogs away. I sometimes let one of the other dogs up to see mum and babies so I can gauge her reaction to having another dog around. Sometimes they don't mind the visitor, sometimes they do.
I normally bring the pups downstairs at about 3 weeks old by which time mum is usually ok with the others seeing them.

I do about 3 weeks. My Mum's are usually OK about that. I have made sure that in the meantime mine have some mixing with the other dogs so no pack problems but to be honest after a couple of days recovery mine are up for it when the leads come out for the other dogs walk anyway and it would upset them more not to go. In those early couple of weeks I think they do need reassurance that when they are not there, none of the other dogs are not going in to the pups.

I should have said I don't keep mum separate from the other dogs. When she comes down to go out she mixes with the other dogs as normal. If she wants a walk then i start with lead walks on her own round the block. I am guided very much by what the dog wants.

My girls are fine being isolated for about a week then want to be back in the centre of daily activity so I put Mum and pups in a crate in the lounge during the day with the other dogs milling about and back up to the whelping box at night with a barrier to stop any other dogs getting in the room.

As the pups get older then we progress to the puppy pen and gradual access from the other adults to go into the pen.

I used to take the pups into the kitchen (where the dogs spend most time, and only way out to garden), at that tiem pusp spent frist two weeks in teh bedroom.

I had one bitch who was overly protective at this age, and since have waited until three weeks, to put them in the larger pen in kitchen.

I now whelp in livingroom (so other dogs not allowed in except quickly through to get into hall to go out for walks), and other dogs seperated from livingroom by gate.
