I am currently renting a house that is 10 years old. The carpet in the house is 10 years old as well. It is very cheap and has a lot of wear and tear. A few months back my dog ripped up a corner where it meets the tile. There is no tacking strip where the carpet meets the tile at the entrance. There is about a square yard of it that is damaged and it is all tattered. I can't just put replacement padding down and lay the carpet over it due to small part of the carpet actually missing. A new 1 x 1 square might have to be installed. (See photo) My question is how do I go about it with the landlord when I move out in three months. Do I fix the issue myself and never tell the landlord or do I try to swing the idea that the whole carpet just needs to be replaced because how worn it is and there is no bother for me to clean or repair it?
