Leonard D. Sale wrote in 1896 in The Horse Review of Chicago that an Assateague resident imported and released a "Canadian bred pony stallion" in an effort to improve the breed. The resulting ponies from the Canadian pony were described as being "course-haired, gummy-legged and large brute". However Wallace's Monthly said that the part Canadian ponies were larger with better necks and head carriage.

The stallion also was apparently gaited as some of his descendants paced, "A few island ponies pace, but they carry an infusion of the Canadian scrub blood." Some Chincoteague Ponies have been found to have the gait gene.
