How can a horse be properly evaluated?
Avoiding injury
The reality of equestrian activities is that death and serious injury, including permanent paralysis, are not rare events. Such outcomes cannot be entirely prevented by proper training of horse and rider, the correct use of sound equipment in adequate facilities, or by riding only under proper supervision - but they can be readily prompted by any or all of the opposite practices. Horse shopping can be a very dangerous pastime for that reason.
Horses are so expensive to transport that a horse is usually first evaluated at its home facility. Despite what is advertised by the seller, this may be a field or paddock that has poor footing for riding and may even be shared by other horses. This is not a safe place for any amateur to ride a new horse for the first time.
Tack may be supplied by the seller for a trial ride, and that arrangement often has the advantage of a bit and bridle that the horse is accustomed to, rather than a novel arrangement. It is not impolite to double check all aspects of the tack rather than take the word of the seller that "everything is fine". The potential buyer is wise to watch the horse being brought in and being tacked up.
The equestrian who is interested in avoiding catastrophe is generally advised to never ride a horse, no matter how safe and well-trained the animal is said to be, without seeing the horse ridden immediately beforehand by a person who is familiar with it.
