First, get a good dog trainer or take a week off work to constantly watch the dogs to catch them in the act. (OK, I know this a building site, but you happen to have landed an architect responder who has a secret life as an amateur dog trainer.)
But even if your dogs are trained, realize heavy dog toe nails can also be murder on some hardwood, although no problem with pups under 40 pounds, usually.
- Linoleum holds up very well and is very green. Check forboflooringna.comandnovaflooring.com)
- Porcelain tile is very non absorbent and economical, but if you have a raised floor, you want to be sure your structure is designed for the weight.
If the dogs are under a year wait awhile so all the trashing is done, the dogs settle down and you can go through this big expense without having to do it again if your new floor gets eaten by the wild savages.
