Smelly entryway in building

I live in NY on the second floor of a walk up and my landlord is on the first floor. He’s a single middle aged male with a dog who keeps his shoes outside the front door of his apartment and it smells as such.

I am seeking subtle hacks to neutralize the odors so when I first walk into the building or out of my apartment it doesn’t smell like dog or BO as much, and that won’t be too overt or offend my landlord. Any tips are appreciated!
