You might notice that Dadaocheng is full of dogs, as well as a handful of cats. As a result, you probably have a higher chance of stepping in something a little unsavory in the neighborhood than you might in other commercial districts, so it's a good idea to watch your step as you navigate the streets and alleys.
Some of these animals have owners, while others are more communally cared for. You may need to step over a snoozing dog or two as they take advantage of the cool stone and air conditioning in front of the shops, but the important thing to note is that these dogs are harmless, despite the general stereotype local people often have of street dogs. When not lazing in front of shops, they're wandering the neighborhood, sometimes playing with each other right in the middle of an intersection, causing traffic to grind to a halt for a second or two before springing to life again.
Dadaocheng locals are used to the occasional dog-related hazard, but if you're visiting, try to be especially watchful when driving or cycling through to avoid injury to both the dogs and yourself!
