I recently had the pleasure of purchasing my Border Collie puppy, Nori, from William at Border Agility, and the experience was absolutely fantastic. From the very start, William was incredibly professional, knowledgeable, and clearly passionate about the breed, which made the entire process smooth and enjoyable. Communication with William was top-notch. He was always quick to respond to my questions and provided detailed information about Nori’s lineage, temperament, and care needs. It was evident that he is deeply committed to ensuring his puppies go to loving and responsible homes. When I met Nori for the first time, I could see the care William had taken in raising her. She was healthy, well-socialized, and had already been introduced to some basic training, which was a wonderful surprise. The love and dedication William puts into his breeding program really shines through in the quality of his puppies. Even after bringing Nori home, William continued to offer support, checking in to see how she was adjusting and providing valuable advice for a smooth transition. This level of care and commitment is rare and greatly appreciated. Overall, I couldn't be happier with my experience. If you’re looking for a well-bred, happy, and healthy Border Collie, I highly recommend purchasing from William at Border Agility. Nori has brought so much joy into my life, and I’m confident you’ll have the same experience!
