As lots of people have suggested Boxers and Spaniels, I’m going to suggest a Boxer/Spaniel cross (mainly because that’s what I’ve got and everyone else is just suggesting what they’ve got!).
He’s not destructive in the slightest, perfectly happy getting a few hours kip during the day whilst we’re at work, great with kids (goes for playgroup walks several times a week during the day with next door’s two terriers and 4yr-old girl, and she has total control over him), will happily run 10 miles with the bike, is a proper rough-and-tumble dog that you can playfight with but will also switch it off and be calm in an instant.
Only downside is that he can occasionally have selective deafness where squirrels, rabbits and deer are involved! And an inability to know his own limits in terms of trying to uproot and carry small trees… 😉
