Kilby'sMum
Super Boxer
The first six months will be tough but it'll be so worth it! I work from home with 2 boxers and I definitely get plenty of time to get stuff done, I usually take them for a walk (45-60 mins) then they have brekky, 30 minutes or so of playtime in the backyard (you could go to the park) and then I start work and they will sleep on the floor in the office. Around the 4hr mark I usually let them out for another 15 mins or so and then back to it for at least another 5hrs. Of course, that's a routine for an older dog and a puppy needs more frequent breaks and attention. We have never crated our girls (luxury of being able to leave them in the backyard when we go out I suppose) but when Kilby was a puppy I ordered a wooden playpen (no base, just four sides) and when Kona was a puppy I'd set that up in the office and put her in it with a few toys and a blanket or a Kong to keep her occupied which really helped because I didn't have to worry about her going where I couldn't see her and because she had plenty of room and things to entertain her there was none of that crying or barking.
On an aside, you mentioned running with your pup - not til they are older I'm afraid. I think you're supposed to wait until they're 18-24 months before running while all their bones and stuff are developing but walking is fine. I have only just started running with Kona (20mths) and it's hard work and she does tire easily so we only go about 4-5km once a week. Kilby (4yo) on the other hand can happily and easily run 15km and I'm sure she could go further if I could ;p.
