It means that the breed has been over-breed. The female is breed over and over, too often and without proper testing. I have heard of lots of Cocker Spaniels with genetic eye problems from over/improper breeding. Overbred is when a dog has litters back to back, usually every 6 months.
The English Springer Spaniel field-bred dogs tend to have shorter, coarser coats than show-bred dogs. The ears are less pendulous. Field-bred dogs are wiry and have more of a feral look than those bred for showing. The tail of the field-bred dog may be docked a few inches in comparison to the show dog.
