>that's even worse then if they take them away from mum and siblings at 5.5. weeks and out to walkers at 6 weeks, its shocking
It's my understanding this isn't correct - when they go into the centre to be assessed and sent out to puppy walkers, the whole litter will go together and be kept together until they go to individual puppy walkers at 6wks. I also believed that mum often comes too, and stays with them at the centre until they have gone to puppy walkers.
Socialisation is paramount for guide dogs, so you can be sure they are following the most up to date guidelines and research - which finds that the best age is 6wks. Not 7 or 8wks.

http://www.apbc.org.uk/articles/puppysocialisation1"Derek found that six weeks was the best time to place puppies in private homes; any later critically reduced the time left before the puppies reached twelve weeks; but if puppies were removed from their dam and litter mates before six weeks they missed the opportunity to be properly socialised with their own kind, which resulted in inept interactions with other dogs in later life. The training success rate soared because of this policy, which was carried out in conjunction with the management of the gene pool via the breeding scheme Derek also pioneered. Annual success rates in excess of 75 percent became common. You might think that this is a special scheme for dogs with a special function. In fact, what the scheme provides is adult dogs with sound temperaments. These dogs coincidentally make the best material for guide dog training which does not start until they have been assessed at ten months or older. "
"Of those in group A we have to take into account the fact that breeders sometimes cannot find enough suitable homes quickly enough. Having said that, it is unfortunate that some breeders believe that most families are unsuitable to look after a puppy when it is six weeks old, although it is difficult to see what suddenly makes a family suitable when the puppy is eight, ten or twelve weeks old. All too often breeders, unaware of the harm they are doing, retain puppies well into and sometimes past the critical socialisation and habituation period so that they, the breeders, have time to choose which puppy or puppies they wish to keep for showing before launching the rest on the unsuspecting public. There is in essence nothing wrong in the breeder retaining a puppy for as long as they want, as long as they systematically ensure that each puppy is properly socialised and habituated as an individual. Each puppy needs to learn to cope with the environment without the support of its litter brothers and sisters and other dogs. Although this is possible, in practice, it is very time-consuming."
"Prospective owners can maximise their opportunities to socialise and habituate their puppies by obtaining them at six weeks old, having already made arrangements for the appropriate vaccination programme with a veterinary surgeon. Of course failing to obtain a puppy at exactly six weeks does not automatically lead to disaster, but the later puppies are acquired the more precious time will have been lost and the less likelihood there is of developing a sound temperament...The prospective purchaser of a puppy can check that some degree of socialisation and habituation has taken place. Ideally, they will have sought out a breeder who will let them see the puppies with their dam in their living quarters prior to the optimum "go home" age of six weeks."
