Can a horse be registered a standard breed if mare and sire are paints?

Yes, a horse can be registered as a standard breed if both the mare and sire are Paints, but it typically depends on the specific breed registry's rules. Many registries have criteria regarding the lineage and color patterns of the horses. If the Paints have the appropriate bloodlines and meet the registry's requirements, their offspring may be eligible for registration as a standard breed. Always check with the specific breed registry for their guidelines.
