How to Choose a Working Cocker Spaniel Stud Dog

Choosing a stud dog is one of the most consequential decisions in a breeding programme. It's not just about what the puppies will look like — it's about their health, temperament and working ability for the next twelve to fifteen years of their lives. Here's how to approach it sensibly.

Health testing comes first

There is no responsible shortcut here. Any reputable Working Cocker stud dog should have clear or carrier DNA test results for the conditions relevant to the breed: PRA (Progressive Retinal Atrophy), FN (Familial Nephropathy), AMS (Acral Mutilation Syndrome), DM (Degenerative Myelopathy), EIC (Exercise-Induced Collapse) and GSD VII.

Beyond DNA, look for a current BVA eye certificate, hip and elbow scores, and ideally gonioscopy (glaucoma screening). A stud owner who can't or won't produce these certificates is a red flag — not because their dog is necessarily unhealthy, but because they haven't bothered to check. And if they haven't bothered to check, that tells you something about their approach to the rest of their breeding programme.

Kennel Club registration and DNA profiling

For your litter to be KC registrable, the stud dog must be KC registered. Always ask for the KC number and verify it on the Kennel Club website. A DNA profile on the stud is also a mark of transparency — it allows any parentage dispute to be resolved cleanly.

Temperament and working ability

With Working Cockers, temperament and drive are heritable traits. Meet the dog in person if at all possible. A calm, confident dog with natural hunting instinct — keen nose, good retrieve drive — is going to pass on more of the right stuff than a nervy or over-sharp dog, however impressive his pedigree looks on paper.

Ask about the stud's working history and the performance of previous litters if he's proven. A dog with multiple successful litters from varied bitches gives you more reliable information than a dog that's never been tested against other genetics.

Complementing your bitch

Think about what your bitch brings to the table and what you'd like to improve. A very wide-ranging, fast bitch might benefit from a more methodical, steadier stud. A bitch that's a touch light in bone might be complemented by a stud with good substance. The goal is a litter that's better in the areas that matter — not just a repeat of what you already have.

Linebreeding vs outcrossing

Some breeders prefer linebreeding (using dogs with a common ancestor) to fix desirable traits. Others prefer outcrossing (using unrelated dogs) for hybrid vigour. Neither approach is universally right — it depends on what you're trying to achieve and how consistent your bitch's lines already are. Discuss this with your stud owner; a good one will have an informed view.
