Remy goes on walks with me all the time however, he has never potty outside. He has always use pee pads. He does his business on the pads and then walks away. I make sure I pick up his poop and flush it down the toilet right away. I have never had an issue with a smell from using the pads. I use to use the disposables up until about a month ago. I now use the pretty awesome pee pads that I got from T Bumpkins & Co and I love them. She is a member on this site and her website is
Washable and reusable dog and puppy pee pads, belly bands, and diapers by T. Bumpkins & Co.. I have about 12 of them and the designs are great. I wash them with Tide, Borax and white vinegar in warm water in the washing machine. I don't use any softener and I dry them on med heat. They come out fantastic and don't smell like urine. I would have saved money had I purchase these a long time ago. I hope this helps!
