Horses are not supposed to be even messed with until they are done growing at 2 some still grow till they are 3 years old.
Say what???? What type of horses do you work with???
No horse in the UK can have a lifetime height certificate done until they are 7yrs old, I believe......surely that would indicate that a horse is not yet mature until that age?
My rising 4yr old hanoverian/ tb is still growing now....he will easily top 16hands and he is only standing at a smidge over 15.2hh at the moment! He stood at 14.3hh aged 2yrs and 15.1 at 3yrs! He has definitely grown since he was 3!!
My just turned 6yr old tb/dutch wb mare has only just stopped going arse high now but my vets still wont agree to have a lifetime height cert done for her, and so I have to have one done yearly for now!
It is V.V.V.V.Very dangerous to belive that a horse is fully grown at the age of 2/3 as that is when they get pushed too hard too soon.
Sorry it is a touchy subjects with me im affraid as I have a nackered old boy with cripling arthritus in his fore-legs due to him being worked/jumped too high too young by previous idiots!
KANSAS TWISTER I had a similar problem to you.....my mom was diagnosed with cancer (a brain tumour) just after I got my horse back from being broken(hate that word) (i had spent a fortune on this event trainer having him for 4weeks). He was just rising 4yrs old and unfortunately the only option I had was to turn him away....
He was out for over 6months and only came back into work once my mother had passed away....i got stuck into training him very soon after to kind of keep my mind occupied I suppose!
IT WAS THE BEST THING I EVER DID!!! He had remembered the basics and picked everything new up super quik. He had filled out and looked like a proper horse, he had levelled up and gained some brilliant manors from being out with a load of other youngsters who had told him whats what.
Aslong as your horse gets the right care and isnt left unattended I would say turn her out! It doesnt hurt at all and also wont cost you ther earth while your spending time with your loved one!
Hope everything works out!
