Short-haired Corgis may give birth to long-haired Corgis. Short-haired Corgis carry the recessive long-haired gene, which means they have the genetic potential to produce long-haired Corgis. Also, short-haired corgis are dominant heterozygotes, which means their offspring may have different coat types.

However, it should be noted that the result of this breeding is not 100%. Definitely, because heredity is a complex process involving the interaction of multiple genes and genetic factors.
