NOT FOR SALE 12mth lease only

We are lookinng for someone to lease miss Sparkles for 12 months, until my girls have enough experience to ride her independantly.
She is best suited to a independant (not beginner) young rider/teen/small adult. Or as a leading rein.
Has been used last 12mths as leading rein pony for 6yo twins.
A 16yr old has been riding her for about a month and she hasn't put a foot wrong.
Sparkles is 12.3 and rising 18
* She has foundered in the past, so needs to be yarded. Has not shown any soreness at all since we have had her.
She scrambles if floated alone. but will NOT whilst floated with another horse.
Other than those 2 things, she is perfect.
**no 1st time horse owners please
** parents or adults only to contact me please.
She is up to date with all worming, farrier and dental. Will be leased with her winter combo and bridle/bit
Contract must be signed. She is very very dear to us and Ivydane who was kind enough to entrust her to us.
The ONLY reason i am leasing her is this way she will still get spoilt while the girls hone their skills. If nobody suitable is found she will relax and spell for this time.
