Awwwwwwwwwwwwwww, my Yorkies are little SNIFFERS as well. I don't mind though because I look at their walks as THEIR time. Time for them to do as they please (as long as it isn't dangerous) and time for them to just BE DOGS.
Although I will update you on that when we are in the middle of WINTER. LOL
It doesn't matter what my Yorkies do. EVERYTHING is ADORABLE !!!!!!!!
