How much it helps depends on the person knowing how much he has or has not learned. When I first got started in horses, Statelinetack had a bunch of free videos by Chris Irwin. Those videos were of enormous help to me, but they didn't pretend to make you a horse trainer. They just helped you with things like: how to best approach a horse, how to lead a horse, how a horse interprets and expresses aggression, how to handle a horse so the horse won't feel bullied, etc. They were great for teaching me why my horses sometimes acted irritated or nervous around me, and how I could make them feel comfortable.
What worries me is when I see videos like "How to start a colt!" Frankly, if you think you need to see a 30 minute video on how to start a colt, you shouldn't buy a colt and try to start him. If you are just looking to expand your horizons, it is fine. But you cannot learn how to train a problem horse from a video.
Mia doesn't have a malicious bone in her body, but she has enough inner demons of fear and a big lack of confidence that she can be challenging for someone like me to ride. But in today's market, there was no one with experience who would have bought her (or taken her in) for the pleasure of training her and selling her, because the end result wouldn't have enough value to pay for her training. So it was to the auction with her, or up to me to find help and try to work thru things with her. She has been a great horse for me, because she motivated me to learn and she pushes my envelope darn near every ride. But she has been a horrible horse for me, because I've never known what it is like to relax on a horse. Every ride is an adventure, but sometimes I don't want adventure. Boring would be nice, once in a while!
I honestly think Mia is at the upper limit for someone like me to ever work with. She was way beyond my limit for knowing how to train her. Even with watching a trainer work several horses, and hours of videos, and books, and advice - those aren't a substitute for 20 years with horses, or for an innate understanding of them. And Mia is, to her credit, a sweetheart. After 4+ years with her, I feel comfortable saying she would never intentionally hurt me...but I can still feel stiffness and a bit of soreness in my lower right back, where she unintentionally hurt me 4 years ago in January.
I think the video trainers provide a valuable service to someone who is willing to admit they also need a human to help them. I think they ruin some horses by giving people the belief that they know how to train a horse even tho they are barely competent enough to lead one on a lead line...
I guess, in the end, for some people, there is no cure for stupid.
We seem to be singing from the same sheet on this one anyway!!!
I cringe when I hear someone say that they have learnt how to catch, lead, groom and tack up etc all thanks to one youtube video trainer (Trainer in the loosest possible sense of the word). All I can say is they're really lucky that they bought a good obliging horse that someone else had put a lot of effort into because really these are things that you need to know before you buy a horse - and then they move on to a challenging one and most often disaster strikes
These are the same people who will tell you if things don't work out that its your fault - that you got it wrong - when in reality its often you are just too far out of your comfort zone or the horse is just too much for you. Some things you can put right and some you cant
I got a horse about 8 years ago that had been point to pointed but not fast enough and the seller thought he might make a nice one day eventer.
I loved that horse from day 1, he was perfect on the roads, he came on really well in his dressage and showjumping but the moment his feet touched an open stretch of grass he was gone. I did a few terrifying cross country courses on him - he never hit anything but I felt so out of control over things that weren't going to easily fall down I knew I was out of my strength zone even in the strongest bit. I had him for a while with a rider who competes at the Badminton level and she said he seriously scared her too so as most of our local rides involved going over fields I decided to let him go - to a 6ft 2 196lb man who hunted him no trouble. He just had more weight behind the bit than I ever could
Could be you need a more solid reliable horse bsms
that will give you confidence and show you how to relax and enjoy riding more? I wouldnt like to suggest that at the expense of anything bad happening to Mia though - maybe a second horse?
