I'm Julie Z., the breeder behind Julie Ziegler located in Deforest, WI. My dog is bred for temperament, health qualities, athleticism, and a keen herding instinct. Both parents have top pedigrees that will be recognized by anyone who has experience in competitive herding - and maybe even those that haven't competed.

We have had a good experience with Julie and our new puppy. She has provided advice and tips that have really helped with raising him. There is no doubt that he came from a caring home and is highly intelligent. I would highly recommend Julie as a source of a border collie puppy. We couldn’t be happier with Pooky.
Health testing is one key piece of responsible breeding and is performed on breeding dogs to prevent the presence of heritable conditions in their puppies.
