We looked at Zip when we got our puppy. We were interested, but have a chain link fence which she can climb. I'm so glad to hear she was adopted and sounds like she's very happy. We got a 6 month old puppy from Denise and he is now 1 yr. 3 mths old. He's great and his name is Leo (our son named him). Denise was so great that we are going to be contacting her for another one. :)
