A dog has a great smell sense: while a human has about 5 million scent glands, a dog has between 125 to 200 million. The part that controls smell is also 40 times larger than in humans. A human can detect a spoon of sugar in a cup of coffee, but a dog can detect the same amount in a Olympic-size swimming pool!
The dog's sense of hearing is also significantly greater than a human’s. They can perceive frequencies twice that of a human. They distinguish sounds four times better than a human.
Now for the question: suppose an anthropomorphic dog species, which is basically capable of talking, moving, manipulating tools, aging and feeling emotions like humans, but with the senses of a dog.
I already thought that our buildings would have thicker walls and the markets would be like an amusement park for them. But what would be the biggest differences in our society if it was built by these species instead of humans (i.e., no humans or dogs evolved in our planet)?
