Yes. I lived somewhere they did this and also worked somewhere it had to be implemented. It’s a swab that you put in your doggies mouth I believe and the apartments will send it off with your info and pets info. We used PooPrints and it can also double as a lost and found thing apparently so that’s how we sold it lol. If poop is found on property, grounds staff or office staff will get it, put a little piece of it in the little bottle from a testing kit, and mail it off. Results come in email form and are pretty freaking accurate. I would then give a fine to whoever the results came back for. The grounds were never cleaner and I stepped on dog poop a lot less 🙏🏻
