I'm Chelsea O., the breeder behind MAF Cattle Dogs located in Montana. We are breeding top quality cattle dogs as family pets as well as horn hunters. All our pups come with paperwork, first vet visit, first shots, and tails will be left alone unless asked otherwise.


Chelsea has been certified by Good Dog's screening team for responsible and trusted breeding practices. When you're ready to reach out, feel free to ask any questions about the breed, their program, or specific puppies.
Together, you’ll choose the puppy that’s right for you, stay in touch with regular updates, and plan how to bring your new puppy home.

"Puppies are priced at $650, $250 non refundable deposit."
Chelsea may provide a written contract or health guarantee when you purchase a puppy. This helps protect both you and your breeder, ensuring that you both have a clear understanding of the terms of your puppy purchase. If Chelsea offers a contract or guarantee, the details will be personalized by them. If you have any questions or want to know more, don't hesitate to reach out to Chelsea directly.
You can drive or fly to pick up your puppy from Chelsea.
