Our Litter Has Arrived — and We Are Proud to Introduce Nimra

We are delighted to announce the safe arrival of our latest co-litter with Ruffian Joannidis — a combination we have long looked forward to. Among these promising puppies, one young female immediately captured our hearts and stood out with her presence and balance. We are proud to introduce Nimra, our keeper from the litter, whose early qualities perfectly reflect the vision and future.
