The experience with Big Zen Aussies has been amazing every step of the way! I’ve gotten 2 pups from them from different litters and cannot recommend them enough! Marissa is super informative and will answer all of your questions in a timely matter. Loved working with them and will definitely recommend to whoever is looking for an Aussie!

⭐️⭐️⭐️⭐️⭐️ 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.
