I suppose I very well could do that. I have the extractable leash, not sure how far it goes, maybe ten feet. He is a little prissy with his "pooping", he likes to hide! Was always wondering if anyone else's yorkies like to get crazy and take off running outside. I did alot of reading about Yorkie's and realize they love to have some adventure and are very curious, and were originally bred to chase small varmits, and Milo does love all of that, but I just feel its too dangerous, but also hate to restrict him to where he doesnt have much of a chance to run run run!!
