No. Many people with large dogs have hardwood flooring. Your dogs will scratch the floors and it will cause more wear; however, unlike vinyl and laminate floors, hardwood can be refinished in the future. Keep in mind that even under normal circumstances, your hardwood floors will scratch. That being said, as hardwood floors age they tend to mellow.

Depending upon the type of system you have, it is usually possible to install ceramic over radiant heat floors. Some applications will require a membrane in between the tile and subfloor. Ask your contractor what is best for you.

One of the rubs against ceramic tile is that it is cold and hard. There are floor heating systems available to make your floor more comfortable to the touch, but in terms of hardness, yes, ceramic is much like hardwood in that it doesn’t have much give. If you want something that has more cushion to it, perhaps you should consider a floating floor.
