Also, when I first start working with the mustang, is it better to do join-up first or getting it to let me touch it? I’ve seen Monty start with petting first using the chute, however since I don’t have that I wasn’t completely sure.

Hi Talia. Welcome to the Uni. Wow! You are taking on a challenge & no mistake. A mustang, born in the wild. I'm guessing, as you don't know its age, you haven't chosen one yet - just advised an interest. That being the case you have time to build chute & a round pen, both of which would be advisable. Not only are mustangs wild, by the time they reach their first owners they are traumatised & very wary of humans having, by necessity, been man handled. Before you worry about which Dually you'll need I suggest you concentrate on the lessons on the Uni regarding mustangs - you are potentially embarking on a very dangerous path, not only for you but also the horse. 

I have no experience of mustangs but I do have a little welsh A ( 11:3 ) who came to me 12 years ago - branded the incredible bucking pony. If I hadn't taken him this lovely little guy would have been put to sleep/put down - for human error! He was a 6 year old lead rein pony. He was bought to show (well bred). Then the owners found out they were to be grandparents so they decided to ride the pony - yes, feet by his knees. Walk & trot were fine BUT no lead rein pony has ever been asked for canter by the rider. I surmise this happened: given canter aid a couple of times but failed to understand so hit with a whip. What happened next I do know. He bucked off his rider. Then he bucked off his riders wife - probably under the same circumstances. Max is a bit cheeky but nothing deserving death! He's 240 kilos but happily carries my 85 kilos, far more in proportion than other equines. Why? Because the ONLY time he bucked with me I dropped my hands, stood over his withers & pushed my legs off his sides ( if you want me off, do handstands )! He stopped immediately, looked back at me as if to say " what's your game "? And the bond was created. 

The danger you are in is making basic mistakes that this mustang will face consequences for. If you get yourself injured - no mustang asks to be in captivity, it'll be the horse that gets the blame. No one is going to believe that you made the wrong choices & the horse simply reacted from instinct. You make the wrong choices & the horse will get the blame, possibly costing it its life but definitely its right to a humane future. IF you do this, do it right, follow the roadmap Monty has put in place. Give yourself the best chance of success, give this horse the best chance of success. Do this right & I wish you every success. Cheers. Jo.

Hi Talia. If you look in the forum history for 'Trust is a two way street' you'll find where I posted my experience with my homebreds & their sire. None of whom are related to Max. Hey, I guess I have an incredible relationship with all of them, thanks to Monty who, started Holy Moley with first saddle & rider in 2019. Go to YouTube, Monty Roberts & Kelly Marks @ SNEC 2019. The first 3 minutes are another horse but then it's my little chestnut mare. Cheers. Jo.

Thank you! 

I’m actually going to be participating in an extreme mustang makeover!! 
(Something I’ve wanted to do for years) which is why I can’t pick it out for myself.
And I do have a round pen set up! 

I’ve been focusing on watching all the videos on mustangs for a while!
Additionally while I am training the mustang myself, my older sister who has already trained a mustang will help me whenever I need it! I plan on being very careful too! 

Fantastic! Sounds like you HAVE thought this through. I wish you great success. To answer your question you will probably want a red or a black Dually. There is an overlap between the two, the red one being the smaller. My red Dually fits all of mine with spare adjustments, including Humphrey, my Irish cob (14 hh) who sired Kirk & Holy Moley. However, Monty uses a normal halter initially with mustangs. By setting it to sit just below the cheek bones & measuring it you could use the orange button to ask which Dually you need. Cheers, Jo.

Thank you!! 

I already have the black one for my horse, so I’ll go ahead and order the red one!
