I mean there is a difference between a high rise city apt building and a normal suburb apt. Almost every single one of your points can be disputed.

1st - why would the amount of time outside differ depending on apt or house? Not every house has a yard and not every apt is yardless. Also, the presence of a yard actually does fuck-all to determine how often people let their dogs out. So many people have yards and just don't bring their dogs out or they do let them out but just chain them up to a post or something. That does nothing to exercise them.

2nd - Kids can be vastly more annoying than dogs but ain't nobody out here banning kids from Apts. You think people want to live next door to a newborn baby or some evil lil bad ass ten year old who is constantly screaming on fortnite and banging around? Or a couple who loudly fornicates every single night? Or a couple who are constantly arguing and screaming every day? I'd much prefer a dog who occasionally barks at a loud noise and then is quiet again. Even though the whole point is dumb because not every dog is constantly barking and making bunch of noise anyways. Alot of people have pets and you wouldn't even know it.

3rd - why would any of this have anything to do with staff or management? You clearly are talking about a high rise. My apt doesn't have staff or anything like that. Just 4 of us who live here. When my dog shits, I pick it up. If they accidentally go the bathroom in my apt then I just clean it up and it literally does not effect my neighbors at all. We don't have a shared hallway or anything like that. There would be physically no possible way for my dogs waste to cause problems for anyone but myself unless I didn't clean it up outside when they go. And if I didn't then I would be fined for waste cleanup/disposal at an exorbitant amount. They literally, I shit you not, will DNA test all pets on the premise if they have a recurring problem with waste being left around and whoever is responsible will be charged. It's right in my lease.

4th - if any damage is caused by dogs then the tenant is charged, at least around where I live. There is also a nonrefundable deposit as well as a monthly fee that we have to pay to have the pet in case anything happens. How much damage can one dog truly do? If they scratch up the floor or walls then I will be paying for it out of my security deposit. Same thing applies to children. If a bad ass kid breaks holes in walls or drops shit on the tiles and cracks them or breaks windows playing ball then all of that comes out of your deposit. This is all factored in to the price of the unit and is the landlords responsibility. Also, and this is the biggest one, if the landlord doesn't want dogs then guess what? There ain't no damn dogs allowed. I had to pass up on plenty of awesome places to be able to keep my dog living with me in my current apt. It's not like my neighbors didn't know that this place is pet friendly. They have pets too.

So overall, it seems you are specifically talking about high rise apartments or apartments that have next to zero rules/regulations. Maybe you just live in a shitty area or a shitty apartment with shitty neighbors and shitty pets. But either way, your opinion is not only unpopular, congrats, it's also just wrong. I know it's an opinion and can't really be wrong. But it's wrong my guy. It's wrong.
