Will tenant Dog scratch up Flooring? Lab/ Dalmation

We are considering renting to a couple with 50 lbs Lab -Dalmatian. They
say the dog is does not even know how to bark and is very tame. I a
concern that the dog will scratch up the vinyl tiles (are delicate) through
out the longs hallway, kitchen and dining room. If a part of the floor is
scratched up I basically have to re floor half of the upstairs, because I
can't find matching tiles anymore (bought 3 year ago). I am also
concern about the dog making too much noise, that could upset the basement
tenant. Anyone with experience with dogs & floors wear? I have never
had a dog, so I don't know what to expect. Any advise.
