The most durable floor types for homes with dogs include bamboo, modern vinyl, stone and tile. Hardwood and carpet both risk becoming stained or damaged by a dog's nails.
Bamboo floors are the hardest wood-based floor and are naturally stain-resistant. Modern vinyl also provides a hard, stain-resistant flooring with the added benefit of being low in allergens and quiet to walk on.
Stone and tiles made of porcelain or ceramic cannot be scratched by a dog's nails and are extremely easy to clean. However, the hardness that makes stone and tile durable can also cause the floor to be uncomfortable for dogs to lie on. Frequently trimming a dog's nails helps prevent damage to all types of floors.
