I just think it's interesting that the planner who made the comment about dogs is based in Edmonton, and having lived there I would take his point of view with a grain of salt. Edmonton has been developing its light rail, but it is still a very car-oriented city. I think it will be some time before it develops the critical mass and density for it to realize some of the things that are working in other North American cities regarding the proximity of jobs, housing and amenities. It is especially hard to densify cities built on flat lands.
Edmonton has an incredible amount of green space set aside as off-leash dog parks. I don't think there's anything else like it in North America. But I'm not sure how much they foster social interaction. Two winters there of walking our dog day in and day out, and we definitely took advantage of those parks ... we found people to be quite antisocial. I think it's the extreme cold. Park usage was definitely way down in winter, and we frequented some of the larger, more well-known parks. Our neighborhood also seemed to empty out in winter. We're talking more than 6 months of the year here. But even when the weather was nice it was hard to really connect with people beyond a superficial greeting. My impression was that people were just very set in their existing social groups and not very open to newcomers.
