Muscle resistance and affect on the horses mouth

“Once the resistances of the muscles are overcome and the animals are balanced, all horses have soft mouths, as the school horses prove, often with very flat bars. If the muscles resist with full force, if the hindquarters thrust more than the forehand supports, etc., the horse will always seek his lost balance in the hand. And then all of them have hard mouths, like race horses who take an arm-numbing contact in spite of the sharpest bars and bits. Thus, the hard-mouthed horse becomes soft-mouthed, when he develops the strength to carry his neck, and the soft-mouthed horse becomes hard-mouthed under a weak rider.” ~ Friedrich v.Krane


The United States Pony Club Manual of Horsemanship: Basics for Beginners/D Level

“A pony who lives outdoors usually has healthy skin and hair and does not need to be groomed daily, except to get him clean for riding and for special occasions. He should be checked over and have his feet picked out every day, whether he is ridden or not, and his eyes, nose and dock should be cleaned. In some parts of
the country, he should be checked for ticks, especially in his mane and tail. Besides that, he will only need currying and brushing with the dandy brush to make his coat smooth. The body brush will not do much good on a pony that rolls every day, and you do not want to remove the natural grease and scurf from his coat, as it protects him from getting wet and cold. After riding, sweat marks should be brushed out or rubbed out with a towel.
