My neighbors have a dog that is medium size . They sleep nearly all the time . They leave food out for her and it's soft and dry food. They also have water for her .
I walk her because one of them can't even walk out the door and the other one can't pick up any poo so if she does take her out then many kids incidentally step or fall into their poo which that neighbor wants to be able to help out but she just lets the dog poo alone because if she tried to bend down to pick it up she would lose her balance.
So no dogs should be without leashes but as soon as night rolls around or if it's a weekend during the daytime without the maitenance people or the manager they let their dog go out to use the bathroom not knowing if she went poo or not .
So I end up helping them out more in reality to help out the dog because since they sleep all the time day/night that the dog more likely ends up peeing on the training pads at their place or poos somewhere inside .
Plus it gives their dog extra company plus it helps clean up the apartment yard so nobody steps in the poo .
