Others may disagree but I always think the key to gaining your horse's respect starts on the ground. If you can control his feet, you control him, as they say. I use voice a lot and don't tolerate barging, big nudges to roll me over and see what snacks emerge from my pocket or failing to back up when asked to from the ground.... all those sorts of things.
I also believe that my horses respond better to my voice commands and fierce tone of voice, rather than anything more forceful. Obviously they get verbal praise as well. As a child I was taught that your VOICE is the most important of the aids (again, others may disagree)
If they don't respect us on the ground, then I think it's impossible to have their respect when we are on board! This approach has worked really well for a couple of difficult horses I've had, and I am ever conscious of maintaining firm but gentle discipline on the ground as the pre-requisite for their respect for the rider.
Hope this helps a bit...
Good advice as always from Faracat and Ancient Hacker (I was worried about you, haven't posted in ages!), but whatever you do don't take your horse's behaviour personally! I honestly don't believe they are trying to be 'naughty' they just need a bit of consistent handling.
Is there anything in particular he is doing which is bothering you?
Ancient Hacker has said what I would have wanted to, much more eloquently!
It might be worth checking out Kelly Marks - Perfect Manners and Perfect Partners books, both are very good and give lots of good exercises to try and things to remember to try and put into practise. I've had my pony almost a year and still refer to these books.
I've also had various in hand lessons, which I found really helpful to get a feel for timing and found it easier to put into practise with another pair of eyes.
I like to interact with my horses without halters or ropes to start with. I spend time sitting near them and sharing their space really is one way of putting it.
The other thing is to be patient and not be in a hurry. Act as if you have all the time in the world.
I forgot to send good wishes to usernamepending - so, good wishes.
And hi Rhino - I've been quiet lately as I've been working too hard (don't we all these days
I'll confess about the voice thing: my mum taught me in my early riding days, I guess I was about 4 years old, that you should always be able to control your horse with your voice, in case you fell off while out hacking and broke both your arms. You could navigate your horse home with all those fabulous voice skills... but I never thought to ask how on earth I was going to get back on the darn horse with two broken arms. Aaah, the innocence of childhood.
