At what age would you introduce...?

I have a young highland pony. I taught him the very basics of lungeing, just stand, walk and trot, maximum 5 minutes each rein, earlier this year when he was 3 years and 3 months. He has only done it 3 or 4 times in total, I won't be doing any more lunging until he is over 4, I'm not a huge fan of lungeing youngsters!
 
agree. lunging on a circle is very tough on young growing bones. damage can be done easily.

TIMING AND RATE OF SKELETAL MATURATION IN HORSES

The Schedule of Growth-Plate Conversion to Bone

The process of converting the growth plates to bone goes from the bottom of the animal up. In other words, the lower down toward the hoofs you look, the earlier the growth plates will have fused; and the higher up toward the animal's back you look, the later. The growth plate at the top of the coffin bone (the most distal bone of the limb) is fused at birth. What that means is that the coffin bones get no taller after birth (they get much larger around, though, by another mechanism). That's the first one. In order after that:


Short pastern - top and bottom between birth and 6 months.

Long pastern - top and bottom between 6 months and one year.

Cannon bone - top and bottom between 8 months and 1.5 years

Small bones of the knee - top and bottom of each, between 1.5 and 2.5 years

Bottom of radius-ulna - between 2 and 2.5 years

Weight-bearing portion of glenoid notch at top of radius - between 2.5 and 3 years
Humerus - top and bottom, between 3 and 3.5 years

Scapula - glenoid or bottom (weight-bearing) portion – between 3.5 and 4 years

Hindlimb - lower portions same as forelimb

Hock - this joint is "late" for as low down as it is; growth plates on the tibial and fibular tarsals don't fuse until the animal is four (so the hocks are a known "weak point" - even the 18th-century literature warns against driving young horses in plow or other deep or sticky footing, or jumping them up into a heavy load, for danger of spraining their hocks).

Tibia - top and bottom, between 3 and 3.5 years

Femur - bottom, between 3 and 3.5 years; neck, between 2.5 and 3 years; major and 3rd trochanters, between 2.5 and 3 years

Pelvis - growth plates on the points of hip, peak of croup (tubera sacrale), and points of buttock (tuber ischii), between 3 and 4 years.

And what do you think is last? The vertebral column, of course. A normal horse has 32 vertebrae between the back of the skull and the root of the dock, and there are several growth plates on each one, the most important of which is the one capping the centrum. These do not fuse until the horse is at least 5 ½ years old (and this figure applies to a small-sized, scrubby, range-raised mare. The taller your horse and the longer its neck, the later the last fusions will occur. And for a male - is this a surprise? - you add six months. So, for example, a 17-hand Thoroughbred or Saddlebred or Warmblood gelding may not be fully mature until his 8th year - something that owners of such individuals have often told me that they "suspected)

Significance of the Closure Schedule for Injuries to Back and Neck vs. Limbs

The lateness of vertebral "closure" is most significant for two reasons. One: in no limb are there 32 growth plates! Two: the growth plates in the limbs are (more or less) oriented perpendicular to the stress of the load passing through them, while those of the vertebral chain are oriented parallel to weight placed upon the horse's back. Bottom line: you can sprain a horse's back (i.e. displace the vertebral physes - see Figs. 5 and 8) a lot more easily than you can displace those located in the limbs.

Here's another little fact: within the chain of vertebrae, the last to fully close" are those at the base of the animal's neck (that's why the long-necked individual may go past 6 years to achieve full maturity - it's the base of his neck that is still growing). So you have to be careful - very careful - not to yank the neck around on your young horse, or get him in any situation where he strains his neck (i.e., better learn how to get a horse broke to tie before you ever tie him up, so that there will be no likelihood of him ever pulling back hard. For more on this, see separate article in this issue).
 
Amazingly I have lunged younsters, and seen hundreds of others lunged as 3yr olds as preparing and part of breaking them in. This over the last 35yrs. Many went on to be very sucessful competition horses, good performers in other sectors and many reaching a very good age whilst still working/enjoying life.......................... Can´t think of any who appeared harmed by the careful educated handler lungeing them. Maybe it all depends on HOW these things are done, and by whom ????
 
there's absolutely nothing wrong with lunging a young horse, so long as you keep in mind that it needs to be on a large circle and for a limited amount of time. in fact, I think its extremely beneficial for them, because it helps them gain balance as well as coordination and muscling before someone actually sits on their backs.
But because of the fact that they are still growing, I wouldn't lunge much before 3 years old :)
 
I wouldn't lunge till they are at least 4 or 5yrs old and only for short periods of time if at all - I personally don't lunge mine, long lining is far better. Lunging doesn't teach a horse to balance it forces it to as it has to to be able to cope with such an un-natural activity and such tight bends. It does damage joints, a horse will get its balance by going in a straight line and turning when you ask it to just as well. No matter how much ground work you do it will never build up all the muscles/balance needed to carry a rider - only carrying a weight will do that.
 
Mine was taught to lunge as a 3 year old.

Was hardly ever done (didn't need to) but i felt it was important that she knew *how* to. Was all part of her early education.
 
I go straight to long reining, I find lungeing bores the heck out of me and the horses!

Most of mine have never lunged.
