I use washables and have for 9 years now plus they go outside also. I have tried the disposable but too costly and bad for mother earth

. I will say there is a down side to them though and that is that once a dog is trained to them most articles of clothing on the floor can be "mistaken" for potty pad once in a great while

but for the most part they work great. I purchase mine new from the nursing home I work at.
