That's really interesting regarding calmness especially when choosing a pup. When you add in the mix of working(field) vs show (English) lab. When we chose our latest addition at 8 weeks, all her siblings were there as the breeder was planning to keep them all until about 10 weeks. We were allowed to take Bramble because of the distance we travelled..6 hours!! They were all socialised with other dogs/cats/children/visitors and of course mum and the sire visited regularly . Everything was hectic in the household but in a very comfortable way. The pups lived in the farmhouse kitchen. They also had a resident "old dog" which was good, as we had older dogs at home. We chose the boldest and most inquisitive of the litter. She has also turned out to an exceptionally calm and thoughtful pup, despite her natural high energy levels. I do wonder how much influence those formative weeks has on a pup. We deliberately were looking for working line, however also just as important to us was how the pup was raised in those early weeks. I mention this as some litters are kept in barns or kennels, and I wonder how much this affects pup in terms of early socialisation and experiences?
