Chewing is an issue with many pets, and anything within your pet's reach is an easy target. Go over your home with a fine tooth comb to identify any chewing damage. Look along the floor trim, the threshold of your front and back doors, and the corners of doors and cabinets. Also don't forget to check carpet, window ledges and screens, especially if you have cats. Often, this kind of damage is better replaced than repaired because the odor from your pets' saliva can linger, even if you sand wood damage down and repair it. Chewed or frayed carpet can likely be stretched and re-tacked by a professional, but only if the damage is along the edges; otherwise it may have to be replaced, as well.
And don't overlook your furniture. If it has evidence of chewing, you might want to consider storing it while you're showing your home because to some buyers, the mere presence of a pet can devalue your home [sources: Evans]. Of course, much like the digging, you can help avoid the chewing issues if you exercise your pets adequately and keep them occupied with a variety of toys [source: Deneen]. This will be important to remember while you're showing your home.
