We have a yorkie, we bought a roll of 2 foot woven wire and made a small pen around the back door, and made sure that we never put her out without being there, due to the Hawks. She is 3 1/2 now and we can leave her out, she now weighs 8 1/2 pounds. My husband got electric fence rods to use with the woven wire, it is really portable, he moves it when he mows and when we have been without a dog, the wire is rolled up. We have done this since 1984, and in 3 different houses. Love those little ones, talk to them softly, they will learn your voice and quiet down. Hugs.
