16th Annual Diamond-McNabb Ranch Horse Sale

It is an honor to bring you the 16th Annual Diamond-McNabb Ranch Horse Sale again with my sale partners Diamond Land & Livestock! This years sale will feature 80+ horses for sale.

Ken McNabb Horsemanship and Diamond Land & Livestock share a rich history, producing quality horses for everyone from the experienced ranch hand, seasoned horseman, to the recreational trail rider.

At its roots, the Diamond-McNabb partnership is born out of two families who love to ride, love to ranch and are dedicated to preserving that legacy. During a rained-out pack trip in 2007, the McNabb & True families discovered that their dreams for the future aligned. Stuck underneath a rain-soaked canvas tent, they talked about combining Ken’s training expertise with the demands of a working cattle operation and using multiple generations to create quality horses that are prepared for any job.

Now, 17 years later, that dream is thriving as Diamond-McNabb continues to produce quality ranch horses who have been exposed to all types of natural obstacles, covered miles of terrain, branded and doctored cattle, and have been brought along as safe, dependable partners. These horses have gone on to be used for trail riding, ranching, fox hunting, mounted shooting, rodeo, team roping, ranch sorting, versatility, and much more.

The 16-Year Sale will be held at the beautiful Powderhorn Ranch in Douglas, Wyoming. Gates open on Friday at 3pm and attendees are welcome to browse the selection of 80+ horses and visit with riders. A barbecue dinner is offered along with a horsemanship demonstration from Ken McNabb. On sale day, gates open at 8am, with an official preview of the horses beginning at 9am. The sale officially kicks off at 12:30pm. Attendees may browse my Ken McNabb Tack Store (featuring McNabb Saddlery, headstalls, reins, bits, saddle pads hobbles, fly care, cinches, apparel & much more) and Powderhorn Gift Shop throughout the weekend and all are welcome back to the ranch on Sunday for Cowboy Church.

Preview horses, watch videos, and learn more about the sale at dmhorses.com. Videos of each horse will also be made available on the Ken McNabb YouTube channel.

Here are just what a couple of our customers have to say:

“I have worked with Diamond-McNabb for three years now and our experience has been great! The online auction process works very well even for a non-technical type like me. I have always found it helpful and beneficial to talk with Hailey, Hannah or Ken about the potential horses. They took the time to learn about our program needs and type of riders before making recommendations. Monte, Tundra and Boone are all doing well and I have found that the ranch horses have a very good foundation to build on for the riders.” -Dick, Multiple Sales 

“Diamond-McNabb is so special to my family and me. Since 2013 we have bought One True Horse x 6. We bought 2 in-person and 4 through online and phone bidding. All have been great. People notice my horses, they are set apart by the way the act in all environments. I’ve made a lot of lifelong friends due to the DM program too.” -John, Multiple Sales 

“Through phone conversations with the Diamond-McNabb staff, Tom and I excitedly drove the 8 hours to attend the 14th annual Diamond-McNabb Ranch Horse sale. We studied the sale catalog, watched the YouTube videos, then made our list and the first person we met was DeeDee McNabb! She was every bit as kind and sweet as she is seen on Ken’s shows. She said, “We need to get you to Ken to look over your list.” Ken, the true and professional horseman, spent time with us as well and we felt like we had just met some genuine new and trusted friends. With intentions to purchase one horse, on sale day Hip #11, Truffle, became mine! As the sale continued, I couldn’t help but feel that Tom and Hip #44, Carmen, were meant to be and so she became ours as well… The sale team nicknamed us “the joyful couple” as our happy family went home with 2 Diamond-McNabb horses. Their training is like no other horses we have ever had! This was our first experience with an auction and every staff member was super helpful, extremely knowledgeable and made us feel welcome. Blessings!”

“I attended my first Diamond-McNabb Ranch Horse Sale in June 2022 and purchased Biscuit, now called Buck. I have owned Buck for 7 months and he always puts a smile on my face. His ranch training has made him a calm and gentle horse who has been great for trail, camping and sorting cows. I have taken him out alone in the creeks and hills, in groups, out to a regional wilderness park for riding and cattle sorting. I have pointed him down the sides of steep hillsides and asked him to climb up loose dirt hills. In short, he has done everything asked of him. He then goes off and takes a nap but is ready to go full blast when you ask him. He is simply a great little guy with a wonderful disposition and is also the hit of the barn with his personal and friendly approach to all that happen by. The sale was organized, professional and enjoyable. All of my questions were answered before the sale and on sale day, and Ken even discussed the horses of interest to me for suitability for my use. Anyone looking for a great ranch horse should checkout the sale.”
-RK and “Biscuit” | June 2022 Sale

“Fitz, now named Liberty, will be the staple for three very happy grandkids for the next few years; loved, babied and pampered along the way. He is such a sweet soul and we love him! Clearly, he knows what he’s doing not only with the grandchildren who adore him(and he adores the attention), but in ranch use as well. So much so that I have gone to using him as a mentor to work our own two-year-olds. He’s calm and level-headed with outstanding hillside obstacle attributes. He seems to put the two-year-old’s at ease to concentrate on the work at hand. We will look forward to your summer auctions in the future with anticipation. Thanks again.”
– BW & “Fitz” | June 2022 Sale

“Hello Diamond-McNabb! I love love love my two DM horses! I know several of my riding buddies wish they had one of their own. The first horse I bought from your sale was in 2016; Hip #34 Levi. The last horse I bought from your sale was Hip #2 Cider in 2022. I reached out via email prior to attending both sales in person in order to shorten my list and received a helpful and honest reply pretty darn quick! I loved that they would honestly identify a horse that would not be suitable for me and suggest others that would. Once at the sale I found everyone still incredibly helpful. Both my horses are exactly as represented. I ride 500-600 miles a year and they are both so solid regardless of terrain or weather. I’ve put many friends on them both (experienced and inexperienced) without needing to worry. Both have a great work ethic and ride off after time off as though they were ridden just the day before. My riding friends like to tuck their horses in behind my two DM horses because they know my two won’t spook or act silly. When it is time to retire Levi I will be back!”

“After meeting her before the auction weekend, I knew immediately that Trixie was the horse for me! I was very unsure about how to bid, etc. so Ken and staff introduced me to someone who could help. On horse sale day I was so excited and nervous, and Trixie was hip #70 so I had to wait a long time sitting next to the man who was helping me. When we got her I was stomping my feet and everyone around me was cheering me on! The next day was Sunday and I attended the cowboy church service given by Ken’s dad. It was a wonderful sermon and I felt that everyone in our country should hear what he said! I felt like I was in a “happy bubble” the whole time I was at the ranch. EVERYONE was so friendly and helpful, like one big happy family. The Diamond-McNabb horse sale is so organized, making everyone feel so welcome! What a great experience it was in getting another horse! Trixie arrived in Idaho a few days later and I am so very thankful to have this very special sweet, kind, and athletic horse.” -ST & “Trixie” | June 2022 Sale

“When I retired, I knew I wanted to purchase two horses, which would allow me to fulfill a childhood dream and share my passion with family and friends. I was familiar with Ken McNabb from RFD-TV and when I discovered he had an annual sale, I researched further. I sensed integrity and sincerity in the content available and felt the representation of faith was genuine. Through phone calls with Diamond-McNabb staff, the online videos and catalog, I determined I would focus my search on the June 2021 sale. After speaking with the Diamond McNabb crew in person at the preview, my wife and I were even more convinced we could come home with two very well-trained horses. Although we could not be certain of getting horses on our priority list, we were confident the horses were represented honestly and the good-fit guarantee gave us comfort. Happily, we came home with two wonderful 8-year-old geldings: Pistol and Pancho. We are very happy with both horses and have confidently had friends and family ride them in the arena and on trails. Their ground manners are impeccable and their talent far exceeds mine. I learn more from them than they do from me. I am hoping to attend a clinic in the future. Thanks to the entire Diamond-McNabb family, Pancho and Pistol are now part of ours.” -S&L and “Pancho & Pistol” | June 2021 Sale

“At 49 years old, I was looking to find my very first horse. A horse suitable for a beginner rider who I could trail ride within the Colorado Rockies. Boy, did I hit the jackpot when I found Magnum in the 2017 sale! Not only is he a trail horse deluxe, he is fantastic working cows. I learned about the Diamond-McNabb horse sale from a gal down in south Texas where I grew up. As a first time horse buyer, I felt completely comfortable purchasing a horse from this sale.  The terms of the sale were very fair and all the folks involved were very helpful, honest and knowledgeable about all of the sale horses. I now have 4 DM horses: Magnum, Aladdin, Duke and Arizona! Each horse I bought turned out to be exactly as described by the comments in the catalog and by the people familiar with the horse.”

“If you are looking to purchase a horse I highly recommend Diamond-McNabb. All four horses that I have purchased between 2010 and 2019 are still with me to this day and anyone can ride them including my wife and grandkids. The Diamond-McNabb employees are very friendly and will help you find the right horse for your needs.” DN & Horses | Multiple Sales

“This letter of reference is for Diamond Ranches and Ken McNabb. We have purchased 4 horses over the past 4 years, one of them being returned per your warranty agreement and repurchased a horse the following year, which is exactly as you stated. We are pleased with everything to do with the sale, your livestock, and the quality of this event. Anyone looking for a good horse I highly recommend this sale and these people. I am planning on going to this next year’s sale, hopefully without my checkbook…haha!” – A&L and Horses | Multiple Sales

“Reviewing the horse sale catalog, online information and previewing the horses on Friday is a must in your shopping process! Remember your riding abilities, and how the horse will be used in your selection. The actual auction was exciting, something I have never experienced before. It was very easy from start to finish and I highly recommend it. The quality of horses is exceptional. Shafter is the first horse I’ve owned that I have not trained myself. He is the very best and is the love of my life. Thank you.” -RT & “Shafter” | June 2014 Sale
