White Saddle Cloth Test -

This is the easiest and cheapest test you can do and one of the best ways to assess fit.

NEVER buy any saddle that you have not taken home and done this test with first. The dynamics of your saddle will of change once your weight is applied to it and the only way to really asses fit is when it is weighted and the horse is in motion.

Ride for at least half an hour, more if possible using only a thin white saddle cloth (or a pale colour) under the trial saddle.  Take enough time to get a good dirt impression from the saddle panels, and then examine your dirt marks carefully.  Most good saddleries will carry some test saddles so you can take them home and even most owners will allow you a trial of second hand saddles.

After all they don’t want you to return them later either.  Sometimes placing a material saddle cover over the saddle will protect it from any marks or damage whilst you trial it.

What you are trying to establish is if the saddle panels are wide enough and disperse weight throughout their entire length, and if they mirror in reverse the shape of your horse's back.  It doesn't matter what type of saddle you choose, English, Stock, Western whatever........... it must pass this test to avoid pressure points.

The saddlecloth imprint will tell you a great deal about the way your saddle fits once your weight is added to it. Spread it out on the ground next to your upturned saddle and look at them both carefully and ask yourself these questions.

Is the imprint even throughout all the areas of the panels?

 

If the imprint is symmetrical and even, you know that your weight is being distributed evenly throughout the entire panel which disperses the pressure over the greatest area.  If the imprint of the panels is in patches, then your saddle does not fit. Dark areas are where the saddle is bridging and there is heavy pressure.

The light areas are not receiving any weight at all.  This creates immense pressure in the dark areas. Dark patches only in the front panels of the saddle indicate that the saddle is receiving all the pressure there and is pivoting off this area and probably moving from side to side at the back causing friction and heat.

Dark areas on one side only?  Maybe you are carrying an injury and are sitting with your weight more on one hip, maybe there is atrophy of the other side of your horse's back.  Maybe there is asymmetrical muscle development due to a clubby hoof.

Dark areas at the back of the panels (often evident with Australian stock saddles) show that all your weight and the consequent pressure to the horses is to the back of the saddle and you are not being centred properly. These saddles are designed to sit you at the back of the saddle with your feet forward and have fairly rigid construction through the pommel which unless they are an exact fit will act like a nut cracker on the withers area.

Check the saddle thoroughly underneath:

There should be no hard spots in the padding and definitely no nasties like bolts or fittings pushing through which would be driven into his back.  These can lay just below the surface and not be seen by the naked eye.  Use your hands and press deeply over the entire padding.

Sometimes stuffing will compact and roll up into hard solid rolls which are hard to detect with your hands but your horse will certainly feel them when you sit on the saddle.

Saddles should also be symmetrical, take the time to really compare one side to the other, look along the channel to see if it is straight.   

The channel up the centre of the saddle should be wide and high.  It should not narrow towards the back as the horse's spinous processes are smaller there than near the withers.  It must be wide enough never to touch the spinal processes or trap the muscles that attach there when the horse flexes sideways.

Panels themselves should be wide sitting just above the shelf of ribs.  There should be no places where the panels have bowed and pushed in towards the spine and no sharp edges where the leather has folded as the stuffing has compressed and become sharp.  It is almost impossible to detect a broken tree unless the saddle is dismantled by a saddler so often these go unnoticed expect by the horse!  

Next place check for dynamic fit – place your saddle on the horse without a saddlecloth.

o        Place the saddle on the horse where you would normally put it but don’t do up the girth.  Put one hand on the centre of the deepest part of the saddle to stop it moving.

o        Put your other  hand as if you were offering to shake hands with someone (it will have to be your left hand if you are facing the near side of the horse).

o        Pass your left hand into the pommel at the withers, deep into the channel, right up to your thumb ( till it won’t go any further ).  Still keep your hand in that handshake position so your fingers lay flat against the horse’s shoulder.  

o        Stiffen your fingers and then pass your hand down under the front panels towards the horse’s foreleg. Keep your hand firmly jammed in as far as it will go but also continue to keep your fingers flat against the horse’s shoulder.

o        Slide it right down from top till it emerges out of the saddle at the bottom. 

o        If the saddle fits well you should feel a little resistance at the top of the panels, but you should be able to smoothly run hand straight downwards with only a small amount of force.  If you find your hand is jammed at the top of the panels by pressure from the tree and you need to use some force to slide it down, then this is not the saddle for your horse as once you add your weight to it, it will surely drive itself into the horse’s withers in the places where your hand became stuck.

You should be able to see daylight all the way along his spine and the front near the withers should give good clearance and not touch his withers even when your weight is in the saddle and a thick saddle blanket is under it.  Once mounted put your hand under the pommel and feel to be sure that the saddle still is well off the top of the spinous processes of the withers.

The saddle should sit level on the horse’s back and the deepest part of the seat should be half way between the pommel and the cantle so the tree can disperse the weigh evenly along its length.  If the back is lower than the front or vice versa then your weight will be forced towards the lower portion and the panels will not bare weight evenly.

Don’t be tempted to adjust a saddle that is not level by placing wedge pads under the rear or front of it, as these tend to move around and cause more problems than they cure.  Saddles that need constant adjusting just don’t fit...give up on them and get one that does.

Next do up the girth and check to see if the saddle is still sitting correctly.  Is it still level?

Does it now appear to want to lift up at rear and dig into the horse's shoulders?

If your saddle will not stay forward without a very tight girth, or you have to anchor your saddle forward with a tight breastplate (which is then damaging your horses shoulder muscles) your saddle is too far forward.  Usually the saddle moves back to the correct position, leave it there! Cruppers also should be unnecessary.

Never stretch your horses front legs out to pull the skin from under the girth.  Horses do not have a shoulder joint like ours and to them this is an extreme stretch and when done to a cold or sore horse may cause a muscle tear.  In fact never stretch cold horses.

By now you may be thinking, oh dear, I will never find the right saddle and feel panic setting in.  It is often a frightening thing for horse owners to acknowledge that their favourite saddle has actually been causing problems.

Be patient and be prepared to try a few saddles.  Once you have an understanding of what your saddle is doing to your horse it makes it possible for you to make informed choices about your next saddle. Saddlery owners today are usually more than happy to assist you to find what you need, after all happy customers are their best advertisements

All saddles will have some impact on your horses back, how much depends on what saddle you choose but regardless of its outward appearance the mechanics of any saddle are exactly the same. Many horses never reach their full potential because training has become a punishment.

Common behaviours that our horses’ will

exhibit if they have ill fitting saddles:

If your horse is exhibiting some of the following then suspect that you have an advanced saddle fit problem already.

First of all does your horse snarl and lay back his ears when he sees you coming with your favourite saddle?  You may love it, he hates it and it telling you so as it makes his time with you a punishment.

Does your horse's back have areas of white hair, or if he is a grey, areas that don't seem to get wet when you hose him?  White hair indicates damage from pressure, usually ongoing and done months ago.  Pressure or friction has actually damaged the hair follicles causing them to grow back without pigment.  Much the same as freeze branding does. 

Areas that don't seem to sweat are also caused by severe trauma killing the sweat glands. 

This damage is often evident under where the stirrup bars exert force in the hollow at the wither. Riding instructors often say that standing in the stirrups lifts your weight off the back.  This is a myth, this  practice does not "take your weight off the horse's back" and unless you have actually learned how to levitate above the horse it just concentrates your weight onto the two points where the stirrup bars attach to the saddle, driving the tree into his back at those points.

Even sweat marks are not a good indication of saddle fit as often areas of earlier damage will not sweat even after the muscles have returned to normal.   Only the white saddle cloth/dirt map test mentioned below will give true indications of fit once your weight is added.

Does your horse have high head carriage or an over developed ewe-neck?  The reasons for this are mentioned earlier in these notes.  This is always a warning sign of serious problems.

Does your horse exhibit head tossing or want to reef the reins out of your hands and stretch his neck downwards? 

This is caused by the horse wanting to relieve the pain from the saddle. By stretching his neck forwards it stretches the ligaments of his neck and back and gives temporary relief to tight muscles. Much the same as we are want to do when we are tight between the shoulder blades.

Does your horse resent girth tightening and 'blow up'? 

Riders still seem to dismiss this as just horse behaviour and I have even seen horses abused and kneed in the stomach for supposedly "blowing up" when the girth is tightened.  This is one of those nasty old wives tales (or should I say bad horse manager's tales). 

Horses never fake discomfort.  They are also not capable of holding their breath deliberately, as this is not a concept they have. What is actually happening is that they anticipate are about to be hurt and become tense.  This causes them to tighten all their abdominal and thorax muscles, giving the impression that they are holding their breath. When they relax after the girth is tightened they appear to deflate! Much as we do when the dentist steps back from the chair and announces "finished" and we sink back down more comfortably into the chair

Is your horse cold backed and sometimes bucks when first mounted? 

This is usually because the muscles of his back have become shortened and are in a very contracted and reactive state.  The application of your weight causes the panels under the saddle to press into these tight sore muscles and the muscle will then cramp.  Sometimes horses will even buckle at the knees when mounted trying to get down and away from this painful pressure.

Does your horse start his ride (or workout) calmly but become agitated and jog and fidget as the ride proceeds? 

Horses who become unsettled the longer you work them usually find that this is the only way they can cope with their sore backs.  These are usually the type of horse who is too polite to buck but is reaching the end of his tether!

Is his back hot or tender to the touch, or have raised areas when the saddle is removed?

These are friction burns. Saddles that don't fit tend to pivot from the girth points. Moving from side to side causing great heat and skin damage. Often owners are told that they can help by placing a thick saddle pad under an ill fitting saddle.  Actually what you are doing is forcing more bulk into an already too small space.  Just like buying shoes that are too small and then wearing them with hiking socks!

Does your horse resist flexing to one or both sides, or not want to pick up his canter leads one way? 

Horses often resist flexing because the saddle panels are too close to his spinal processes.   The part of his spine you can feel along his back is just the top of long spinal processes, which rise up from his vertebrae.

Many muscles and ligaments have attachments to these processes and they do actually move quite a lot under the saddle.  It is important that saddles with a channel down the centre don’t trap these processes and prevent movement and that saddles without any channels such as Western style saddles have very thick soft pads under them and that they are never used on thin horses who have atrophied backs or they will place a lot of pressure on the spinal processes once the rider's weight is pressing the saddle down.

Remember these types of saddles were originally designed to be able to rope and anchor a full grown bull to the saddle horn. They are unyielding and solid and their girthing system was designed so that they would never pull sideways around the horse. They were purpose built for working stock and not meant for casual trail riding.

A word about “girthy” or “cold backed” horses.

The girth presses on the pectoral muscles under the chest and against his sides where the serratus muscles lay over the ribs.  Both these muscles are thin and easily made sore.  The pectoral muscles bring his legs backward with every stride so every stride causes discomfort if they are damaged.  Pear shaped horses have all this force concentrated on a small area of pectoral muscle directly under their belly.  Girths need to be as wide as possible and in a neoprene sleeve so as not to crush these muscles. 

The fashion at the moment is for long girth points, which extend below the saddle.  These cause areas of direct pressure against the horse's side where the thin serratus muscles lay.  Be sure to buy a wide girth with plenty of material behind the buckle to protect the horse’s sides. Just as wide panels spread the forces so do wide girths.

Western style cynch setups are also responsible for a lot of damage to the serratus muscles and the steel rings can cause circular areas of muscle atrophy if these girths are done up too tightly.  Their very design allows for a huge amount of leverage and owners should be aware of this.

Sometimes girthyness may be due to nerve dysfunction to the girth area creating altered impulses.  This may be from damage to the stay apparatus muscles of the forehand from long term hoof problems or spinal trauma that needs investigation by a veterinary chiropractor.

Don’t do up your girth when you are sitting in the saddle.  This gives you way too much leverage force from above. Check tightness by passing your fingers under the front section between the horses legs.  Not just behind the elbow where there is a natural hollow or you will get a false impression of the tightness.

If your girth needs to be very tight to keep the saddle from slipping then your saddle doesn't fit properly.  If you saddle fits well then the girth should be almost unnecessary unless the horse shies.

Avoid pulling the saddle sideways around the horse when you mount.  When this happens the girth also may pull the pectoral muscles sideways and upwards. Some horses become so frightened of this pain they will not stand still for mounting. Putting a girth sleeve over the girth will prevent this as then the girth moves in the sleeve and doesn’t pull directly against the horse’s sides.
