It's not the possible threat of a fine that makes me pick up!! I do sympathise with owners who have big dogs.. aren't we lucky to have fallen in love with yorkies?! Yes, I always pick up...I have this great little bag that attaches to the loop of the leaad which you can fill with 2 bags (just right for our two girls!) and there is also room for little treats and a whistle can be attached so when they are running free they can be bribed into returning! As I never take this bag off, I always have bags although I carry extra in my bag too.
I sometimes (no, often!) wish that there were more bins and I didn't have to carry it for ages!!
