Professional Education

Horses in pasture

Training horses, caring for them, and teaching riding, each require different skill sets, each of which is specialized. Until we develop a program specific to Maryland, HSM will recognize anyone who is certified or licensed by a program on our list as an HSM Equine Professional.

Mare and Foal Nursing

Our mission is to support breeders in Maryland who are purpose-breeding for sport, regardless of discipline, and to help those breeders market their horses outside the state. Any Maryland breeder that meets our qualifications is eligible for our breeder benefits.

The ethical treatment of equines in sport requires us to balance the competitive demands that we place on horses and ponies with and their physical and mental well-being. Our horses are our athletic teammates, not pieces of sports equipment.

Maryland Pony Breeder of the Day: Casey Edinger and Slackwater Farm

Welsh Ponies

Casey Edinger at Slackwater Farm in Dameron, St. Mary’s County, is one of the country’s up-and-coming Welsh pony breeders. Thirteen of her Section B and Section C Welsh are registered with WPCSA, and most of those are also registered with the US Equestrian Federation. Her first registered foal was born in 2018; the most recent was born last April. She was the Champion Welsh Breeder at the 2022 Maryland Pony Breeders Yearling Futurity. Edinger uses a few bloodlines in her breeding program that are not currently seen in many of our Maryland-bred ponies. Two examples are her 2023 Welsh cross Slackwater Mischief Managed, who comes down from Kristin deLuca’s German Riding Ponies in Connecticut; and her Massachusetts-bred broodmare Ashland Ginger Rose, who brings in the Glanteifi bloodlines from Wales and the Gallod pedigrees from Canada. The WPCSA registry is filling with more Slackwater ponies every year, to such an extent …

Maryland Sport Horses

Thoroughbred bloodlines are the bedrock of the modern performance horse. Not only are Thoroughbreds excellent all-around athletes and keen competitors in their own right, the European performance breeds carry significant amounts of Thoroughbred blood in their pedigrees.

Thoroughbreds have been in Maryland since before the American Revolution. The first recorded Thoroughbred race in Maryland was in 1743 (the Annapolis Subscription Plate), and Selima, one of the foundation mares of the American Thoroughbred, was imported in the 1750s to Belair in modern-day Prince George’s County. The Thoroughbred is the State Horse of Maryland.

A majority of sport horses bred in Maryland carry Thoroughbred blood. Some are full Thoroughbreds. Some are European performance breeds that that are themselves dominated by Thoroughbred blood. Some are Thoroughbreds crossed with a European breed. And still more are Welsh and Connemara show ponies crossed with Thoroughbreds.

The Maryland Sport Horse Registry records five-generation pedigrees of Maryland-bred sport horses and sport ponies.
