⭐️⭐️⭐️⭐️⭐️ Marissa has been amazing from start to finish! She was so easy to communicate with and always happy to answer my questions and coordinate a seamless pickup. You can truly tell how much love and care she puts into her puppies — they’re healthy, happy, and so well socialized. Our sweet girl came to us confident and loved, and we couldn’t be more grateful to Marissa and Big Zen Aussies for giving her such a great start in life.
