Signs of a Bad Saddle Fit for your Horse
You should be able to stick two of your fingers between the saddle gullet and your horse’s withers. The saddle should have even contact along both sides of the bars. After girthing up, your saddle should look even on the horse’s back, not tipping up or drooping down.
Body Language. A horses who is irritated may stomp his feet. Pawing with the front legs usually indicates boredom or stress, but some horses will do this when angry. His hind leg may be cocked or raised to indicate irritation or that he may be preparing to become aggressive and kick.
There is no one answer but on average I would say 60 days. I have seen as little as one week, but usually the first 30 days to get the horse on board then add instructions the second 30 days.
For most breeds, this will occur when the horse is approximately 2 years old. Some trainers choose to start training when the horse is a late yearling, meaning he is between 18 and 24 months of age, while others will wait until a horse is 2 1/2 before training starts.
Teaching the yearling to carry something on their back won’t hurt them at all. Get them use to carrying a saddle pad, but introduce it slowly as you don’t want to get them scared of it. Let them smell it before you ever put it on them.
Place the saddle on your horse’s back. If it fits correctly, the saddle should look level with the pommel while allowing the cantle to be one inch higher than the pommel. Attach the girth and tighten, making sure that you are able to fit at least two fingers in between the pommel and the horse’s withers.
Look at his ears
To know if your horse loves you, you have to learn how to observe and interpret the movements and positions of his ears. If he has loose and relaxed ears around you, it’s a sign that he feels comfortable with you. Another positive sign is that the horse keeps its ears slightly back when being ridden.
