A dog house is a small shelter designed specifically for dogs, providing them with a comfortable and safe space outdoors. Typically made from wood, plastic, or metal, these structures protect dogs from harsh weather conditions like rain, snow, and extreme heat. They come in various sizes to accommodate different breeds and can be insulated for added comfort. Many dog houses feature a sloped roof to allow rainwater to run off easily and may include ventilation to keep the interior cool. Some owners personalize their dog houses with paint or decorations, while others opt for more functional designs that prioritize durability and ease of cleaning.
