WA state landlord tenant laws, replacement of carpet, tenant's responsibility

carpet replacement basics for WA State: my mother has licved in an apartment for 17 years. For the past 4 years she has had a dog. There have been a few accidents and the landlord wants to replace the carpet but wants my mother, a senior, to pay for the carpeting. I do not oknow how old the carpet was when she moved in so we will use 17 years as an age indicator for the carpet. Should she have to pay for all of the cost of the carpet replacement. We just painted her apartment at our expense since it had never been painted. - Is this your question? Add additional information
