You do not have to own an ass to breed with one!

Conveniently located right outside the heart of Missoula on our ranch is some of the best stock out there ready to help you build yours! Our Mammoth Jack does not get to stay home long these days but he seems to be okay with that!

We do currently have a wait list for our breeding donkey so please reach out via the form and let us know what your ideal time frame would be & we will let you know when our guy is available to come to you! 

testimonials from our clients

Bob is a very friendly and helpful breeder. He was very forthwith with info about his donkeys. I recommend him to anyone looking to learn and get one. Especially those looking for Mammoth Donkeys who are harder to find and raised by experienced trainers.
