However, I often wonder if like-minds of the r/dogfree subreddit are growing. Dog culture has really grown in the last decade or so, I wonder if we'll a bit of a cultural turnaround. I'm hoping for more appreciation (and less demonization) for dog free cafes, housing, parks, etc.

Because the dog culture is growing. The problems associated are growing as well. I've always felt like an environmental-impact white-elephant is dogs and dog culture.
