I live in apartment they allow pets but i had to put down a $250 dog deposit and get renters insurance.
My dog is a barker. if i leave a room, leave home or someone knocks on door or rings the bell he barks. I try to not him bark as much because i'm sure the neighbors get annoyed with it as most of them are old. and you have to watch them CONSTANTLY living in apartment.. when their puppy they LOVE to chew. i have a 6 month yorkie and he has chewed on the corners of the walls and chewed a section of the carpet in corner out. so i had to have all that repaired before our big inspection came last week...
i would look into getting another apartment that is pet friendly.. trying to sneak a dog in and out when their not suppose to be there. is quite difficult.
good luck!! yorkies are the best babies in the world
