Thank you Deb! My neighbor has no problems with little Milo coming to visit, I just about have a heart attack every time he runs up there because before I got him I had a mini schnauzer that I had for 6 years, moved to the country to my husbands farm, and one day i let her out to potty and she never came back. we looked everywhere. We have a VERY large hawk that lived in and around our barn, as well as some large owls, I think these predators ate my dog, and a bouncy little yorkie may look like a rabbit! lol. If i lost him I dont know what i would do, So i thought about getting a female yorkie this spring as a playmate for him, and so maybe he would stay close. We have a lab, but he is a hunter, and often isnt around for milo to play with! thanks for the help though, i also dislike shock collars, just didnt know what i should do!
