There's a dealer that sells cobs and hacking horses, near Gatwick http://www.hackinghorses.com/index.php But generally http://www.horsemart.co.uk I find is a sort of all round selling site. They have categories, and most 'hacking' horses come under, light hack, family and cobs I believe
Beware of doing what most people do, in assuming that something that's been in a riding centre/trekking set-up will fit the bill.
Most horses that have survived in that environment have learned to cope with every Tom Dick & Harry using their mouths as a balance strap and every numpty rider using them as a kick-a-long, and usually have developed bad habits along the way, which they'll try-on with anyone new. Also you have to bear in mind that in a riding school they get a fair bit of regular work and routine, and in a new home without that level of work they'll frequently get bored and bad habits will surface. So beware!!
Sorry can't recommend anywhere. Technically a good dealer or agent should be able to find something; but its finding the "good" dealer is the problem.
Word of mouth is the best thing; but these sorts of horses/ponies are like hens teeth to get hold of and what's frequently advertised as a "happy hacker" frequently is either spooky, has issues, is terrified of traffic, or pulls like a train etc etc.
I'm looking for someone o loan mine as a happy hacker, genuine been there done it, now needs to not school and jump due to arthritis. Not spooky great in traffic, we are out there! I'm way too far away to help I'm afraid.
i second this- i fell into this trap and bought an ex riding school pony- she was far from a confidence giver when in a private home, yet was everyones favourite at the riding school
Riding school ponies tend to just 'follow the one in front' and therefore can be really nappy, we had one as my sister's first pony.... he bolted across 3 fields with her and the PC told us that "he was too dangerous to be in OUR pony club".... we kept him for 8 years, and now he lives down the road from us, and is still being ridden at 28 still a nappy bugger though haha
My big cob Billy was in a riding school for 8yrs before I bought him he was idle and very hard work. I defintely would reccomend that my friend goes down that route she really needs something sensible to grow old with x
Why don't you look at The Veteran society? or one of the equine charities to see if they have a happy hacker available? free up the space for another horse?
