Using only non-toxic paints that won't harm your dog, you can paint the outside of the house to match your own, or pick a fun theme like an underwater scene. If you have small children, it can be fun to allow them to paint the dog house as an art project. To keep the dog house extra dry, you can cover the entire roof with asphalt-impregnated roofing paper, or tar paper. Once you've covered the house, you can then add shingles for a traditional, sophisticated look. Keep your pup comfy by adding a blanket, dog bed, or piece of carpet inside. To add carpet, simply cut a piece of carpet to dimensions one inch smaller than the floor panel and secure it to the floor. Use wood glue if you want the carpet to be permanent, or duct tape if you want to be able to replace the carpet at a later time. Hang a name plate with your pooch's name over the front of the opening using a small nail and any type of material sturdy enough to withstand the elements. You can get personalized plates made of metal, make and paint a plate out of wood, or even hang spare dog tags. Make sure that the nail does not poke out to the inside of the house. Attach small hooks to the outside of the dog house to serve as a place to keep your dog's leash or any other toys.

Summary:
Personalize your dog house with paint. Create a sturdier roof. Furnishing the inside. Add fun accessories to make your pup's house a home.
