The outside of your home is the first thing potential buyers will see, so it's the first place you should look for signs of pet damage. Assess the exterior of your home, as well as your landscaping for problems. The most obvious issue to address is holes in the yard from a dog that's been digging. Make sure to fill any holes -- large or small -- before you open your home to buyers. And to stop the dog from digging further, some trainers suggest filling the holes with bricks or rocks (then cover over with dirt so they're not noticeable). Obviously, giving your dog plenty of exercise each day, and other fun chew toys, could help deter him from digging in the yard, as well [source: Deneen]. Another problem to be on the lookout for in the yard is damaged plants. Both dogs and cats often chew on plants and other shrubbery, so replace any sad looking greenery and don't let your pets near the new ones until your house has sold.
Pets can also wreak havoc on your porch, deck, fences and the exterior of your home. Inspect these structures for chewing and scratch marks. You can fix most of these with sand paper, wood fill or plaster, and paint or stain. If your deck or fence has a liquid stain, make sure you pre-treat the area with a waterproof primer to seal in the stain so it doesn't reappear [source: Kilz].
