The first time the dog chewed up the carpet in this apartment, the tenant paid to have tile installed to replace the damaged area. This time he was again afraid that there was no other option. After searching online, he found MCR and we were able to repair the damage at a fraction of the cost to replace the carpet or put in tile. We could have saved him money the first time around but hindsight is 20/20. At least now he knows if it ever happens again.
