We have a little dog and almost the whole house is carpeted. I am considering going to something else, but it is not because of my little girl dog. It is because of my husband. We have been married for 27 years, and I still don't have him house trained. Only took a couple of months for Josie and we used potty pads. We had one in every room. Now we only have one in her room in case we are gone when she decides she has to go.
