Different tests answer different questions
- A DNA test looks for a specific genetic variant, such as HUU.
- A clinical eye examination assesses the eyes on the examination date.
- A radiographic scheme assesses hip or elbow joints.
- A BOAS functional grade assesses breathing before and after exercise.
Confirm that the result belongs to this dog
- Registered name and registration number.
- Microchip number or another reliable identifier.
- Laboratory or recognised scheme, date and result.
- Agreement between the tested parents and the litter pedigree.
Clear, carrier and affected do not grade the whole dog
These terms refer to one variant and its inheritance pattern. A carrier of a recessive variant is not necessarily ill, but mate selection should prevent genetically affected puppies. Interpretation requires the test, breed and both parents to be considered.
What to ask the breeder
- What are each parent’s strengths and risks?
- Why was this particular pairing chosen?
- Which original results can be viewed?
- What should the puppy’s family monitor throughout life?
