Pets are typically thought of as family. We love them, and most of the time, we forgive and forget when it comes to accidents. However, when your pet decides to accidentally use the carpet as a scratchpad and cause more damage than just a stain, you'll forgive faster than you'll forget. Now every time you look at your carpet you get those "sorry eyes" from your pet, that'll get you questioning whether or not you can fix the existing carpet or if you may need to replace it.
Carpet damage can often times be repaired. Carpet repair is done by cutting out the damaged areas and replacing those with fresh patches of new carpet. Start by measuring out the damaged area, It helps if you have saved some carpet remnants from the installation, but if not then you will need to go purchase more carpet.
