Hi there!
My girl is almost a year and a half now, but our puppy schedule was very similar to what Dutchy said above - the first few weeks were exhausting, with pee breaks during the night, etc. But sticking to a routine helped BIG TIME. As for a feeding schedule, I fed her three times a day (as close to the same time every day as possible), and had a lot of puppy-safe chews on hand.
Now that she's older, we still stick to a rigorous schedule, except minus the midnight potty breaks and plus a lot more exercise.
5:30am - Get up, go for a 45 minute hike (on trails in a mountain park) - a mix of 'free style sniffing' and 'focus / heel'
6:30am - Breakfast - dry kibble in amount recommended on food bag
6:45am - I have coffee, while she gets a chew of some kind (which supplements the kibble - dried yam, Yak cheese, pizzle, "jerky", trachea, etc.)
7:am - I get ready for work, she watches cartoons on Netflix (seriously - I've found the tv on the background helps calm her down so she doesn't feel like she needs to be with me "helping" me put on my makeup)
7:45am - I leave for work, she goes in the crate
11am - Dog walker lets her out of the crate, takes her for a half hour walk (free style sniffing), and then just hangs out with her in my backyard for a half hour
12pm - I'm home for lunch, do approx. 30mins of "cardio" (fetch, fast paced walk, etc.), then 15 mins of training (using a toy or tug as incentive - so still very active)
1:30pm - I go back to work, she goes in the crate
5pm - Home from work, one hour walk
6pm - "Cardio" (fetch, tug, agility on homemade course in yard, etc.) or tracking
7pm - Dinner - dry kibble
7:45pm - She gets a chew (marrow bone, etc.), a stuffed Kong, or a treat puzzle, and we just hang out around the house / yard
9pm - Training session for 15 mins, and then cuddle time / grooming
9:30pm - She goes to bed
A few things to note:
I generally try to avoid dog parks (my girl plays rough and isn't really a fan of them...and I don't trust strange dog owners), as well as doggy daycare, etc. When she has gone to daycare in the past, her behavior has suffered and I end up getting a wild animal back. Although I don't really make time in the schedule for time around other (strange / unknown) dogs, I do have a few friends with well behaved dogs, and we occasionally will meet up for a walk together, or just for a backyard play date. Something to consider, if you are planning on enrolling your dog in daycare, etc., is that sometimes dogs are just not suited for it so you may need to adjust your plans. When I do need to leave my girl (for travel etc.) I am fortune enough to have a local GSD breeder (and president of the IPO club) who will board her; it's structured, supervised, and not a free-for-all with dogs running around acting like heathens.
Also, on days when I go out in the evening (drinks with friends, etc.), we still stick to this schedule right up until 7pm, at which point she is crated and I go enjoy the company of humans. My girl is pretty drivey, so it's just not realistic for me to go out any earlier without her getting destructive, frustrated, etc. One of the "sacrifices" (which I don't really mind at all) about making room in my life for a dog. I know she will likely settle eventually, but until then I accept that as her sole caregiver I simply don't have as much free time as I once did. There's no such thing (at this point) as grabbing a quick dinner with co-workers right after work, going to an early movie, etc.
That said, on weekends we spend a lot of time hiking, swimming, exploring the forest, etc. - typically leaving the house at 8am and not returning until dinner time. I wanted a dog who could keep up with my active lifestyle, so I don't mind that she requires a lot of exercise and stimulation. It's possible that I've kind of conditioned her to be a 'super dog'.
