I also took pictures of where you can see them in X/Y. Wild furfrou can be found near Lumiose City. My favorite is the one in Coumarine City, whose owner gives you the white Silk Scarf. It's a quiet harbor town with cobblestone streets and white boats bobbing up and down in the water.
This past Sunday, we met a poodle and his owner in the church neighborhood. He was very friendly and soft :) I was thankful for this "one-time, one-meeting" (一期一会). *hugs fluffy*
