Register Your Horse, Pony, or Miniature

A PtHA® Color Registry Horse must have four square inches of cumulative white in the qualifying zone and underlying pink skin. May be registered with an approved outcross breed or be of undocumented parentage.

The color requirement is modified with the size of the horse requiring only three square inches for ponies and two square inches for miniatures.

The PtHA® Color Registry does not accept any horses with Appaloosa characteristics, nor Mules or Donkeys.

Horse stallions cannot be registered unless both parents are registered with PtHA® or a PtHA® approved outcross breed. Pony, Miniature, and Utility horse stallions can be registered with undocumented parentage.

For example, but not limited to: Pinto, Paint, Quarter Horse, Arabian, Saddlebred, Thoroughbred, Warmblood, Draft, etc.

The two color patterns are the Tobiano and the Overo. The Tobiano coat appears to be white with large flowing spots of color, often overlapping. Spots of color typically originate from the head, chest, flank and buttock, often including the tail. The Overo coat appears to be a colored horse with white markings. Spots of white appear to be jagged and usually originate on the animal’s side or belly spreading toward the neck, tail, legs and back. White almost never crosses the back.


The Pinto comes in four different classifications – Miniature, Pony, Horse and Utility.

A miniature Pinto is any equine measuring 35 inches or less. A Pinto pony is any equine measuring more than 39 inches to 56 inches. A Pinto horse is an equine measuring more than 56 inches or 14 hands.
