I know this is an old post, so hopefully your horse is sound and healthy your husband has a great horse and your at a barn with a trainer you can agree with.
I personally think that what has happened in the show industry and especially with the hunters and dressage horses is ridiculious. I don't know what your previous horse experience is, but alot of trainers try to keep you in the dark strictly for profit. What you don't know they are going to charge you for. She will get an agent fee 10% a finders fee 5% will charge to go look @ the horse. So she already makes $2-3,000 then the horses training +$ ,board +$ , lessons+$. You can have a showing "green" thats not green. Also look at other disciplines funny how a teenaged actually been to the olympics Eventer who does dressage[HUS] and Jumps[stadium] can be bought for $80,000 but you can't touch a "Hunter" for under $1000,000. Look outside the box, QH are wonderfully athletic and very safe and forgiving great husband horses. Hate to see anyone being taken advantage of, there are enough clients/horses that trainers need to start putting honesty back as the # 1 priority.
