It depends on how old they are, Kanga, obviously a 6 week old will have a different routine to an 8 month old (just like babies!) But basically, they start off with 3 feeds a day which eventually drops to 2. They need to be let out for a 'busy' after each feed and regularly during the day (although, again, this depends on their age and ability to control their bladder).
Once they've had their jabs and can walk outside, they usually need at least a walk a day. I can't remember exactly what they recommend, but it's nothing ridiculous. Your supervisor will advise you when the puppy is ready to be let off the lead and will probably accompany you for the first time you let him off. It's also good to fit in as many 'experiences' for the pup as you can - trains, supermarkets, school gates, brass bands, police sirens, etc. and just general socialisation - but there's not some kind of strict list of things to do and when.
The rest of the time, they're just like a normal pet dog. They'll need to play lots and sleep lots and will probably chew your home to shreds and eat items you never considered remotely edible (twenty pound notes, venus fly traps and sunglasses, that kind of thing).
A 'routine' as such isn't really encouraged, because the dogs really need to be as flexible and resillient as possible for when they're working Guide Dogs who will have to adapt to whatever life brings with their owner. Obviously you can't leave them for long (I think 4 hours was the max they recommended) but they're not really any more demanding than any other puppy. In some ways less so, because you have someone following your progress who will always be able to share tips and offer their wisdom.
I'm excited for you! Let us know how you get on.
