Wife and I have looked into getting an indoor dog, but have some reservations with the possible damage they could do to our floors. We have carpet and wood laminate in our house. Will they scratch the wood laminate flooring? Any breeds that are worse than others for this? Any other tips/suggestions? We would really like to get an indoor dog, but we ( me more than my wife) hate the idea of causing our floors to wear out faster/get damaged just for a dog. Thanks.
