horse of a different color
Horses are registered at
birth, and the registration includes a record of the horse's
color. When a horse trades hands due to sale, the registration
is also transferred. Sometimes the color recorded on the registration
may not match the actual color of the horse, leading one to
suspect the horse is not the one in the registration.
horse sense
Horses are intelligent
animals. They demonstrate the ability act sensibly and to avoid
situations that might cause them harm such as taking a fall,
hence good common sense.
long in the tooth
The age
of a horse can be roughly determined by examining its teeth,
since a horse's gums recede as they age. The longer the teeth
of a horse appear to be, the older the horse.
