H
- HALF KEG OF SHOES
- 50 pounds of shoes. From the days when horseshoes were sold in small wooden kegs that contained 100 pounds of shoes.
- HAND
- A unit of measure equal to 4 inches, used to measure the height of a horse at the highest point of the withers. The number of whole hands is properly followed by a hyphen, then the remaining height in inches. Thus a horse who measures 5 feet and two inches at the withers would be designated "15-2 hands". This is sometimes written with a decimal point replacing the hyphen, which is inadvisable because the decimal point is, on some rare occasions, used to designate following tenths. Hence the 15-2 hand horse might also be designated either "15.2 hands" or "15.5 hands".

- HOOF CAPSULE
- The insensitive, outer elements of the hoof which function as a "wrapper," encapsulating and protecting the sensitive elements of the hoof. Although the term would generally apply to the hoof wall, it could also be inclusive of all the exfoliating elements: the sole, the frog, and the periople.

- HOT FITTING
- Often, but not always, done when hot shoeing; holding a hot shoe against the prepared bottom of the hoof until it scorches it sufficiently to indicate high spots of horn which need to be removed to make the surface of the hoof level. This fitting can be done cold by close observation but requires more skill.
- HOT NAIL
- See: Close nail; Quick.
- HOT SET
- To briefly press a hot horseshoe against the bottom of a horse's hoof. This is traditionally done as an aid to leveling the hoof and shoe, and to burn clips into the hoof wall. Hot setting has also been recommended as a way to kill surface germs and to seal the perimeter of the sole. Aka: Hot fitting.
- HOT SHOEING
- Horseshoeing with the aid of a forge. May involve fabricating the horseshoes from barstock and/or hot setting.
