Parson Russell Terrier

Lifestyle Needs

Parson Russell Terrier

The Parson Russell is a working Terrier which has three coat types: rough, broken coated and smooth.  He is typically a robust, lively and intelligent little dog.  He adores human company and loves to be involved with family activities.  He will bark loudly if strangers call or if he gets excited chasing prey. Ideally he would prefer a country lifestyle with plenty of opportunity to run free.  He would also benefit from activities such as agility to challenge his mental and physical energies.

Genetic Diversity
(Known as Coefficient of Inbreeding: 'COI'. It should be as low as possible.)

The UK Kennel Club breed average COI is 10.0% - See 'A Beginners Guide to COI'

Gene Pool Size
(Known as Effective Population Size: 'EPS')


EPS is a measure of how many individuals are contributing genetically to a breed population. It is a measure of the size of the gene pool in a breed. Lower than 100 is considered critical by conservationists and below 50 brings a breed close to extinction. For more information see the Kennel Club article.

Health and Welfare Problems due to Conformation
(Body shape and physical characteristics)

None known

BVA/KC Health Schemes:

  • Eye disease:  Primary lens luxation (PLL) (annual testing or DNA test – see below)
  • Hip Dysplasia

Estimated Breeding Values (EBVs) : No EBVs are currently available for this breed

DNA Tests Available
DogWellNet and IPFD Harmonisation of Genetic Testing for Dogs (HGTD)

  • Primary Lens Luxation (PLL)
  • Late onset Ataxia (LOA)

Availability of a DNA test does not mean that it is always necessary or even desirable for breeders to use this test.

Other Breed-Specific Health Screening Schemes

  • Patella test
  • Brainstem auditory evoked response (BAER) test for deafness

Ask the breeder to show you the certificates for the above tests/screening for both parents. If any of the above tests have not been considered necessary by the breeder (and there may be good reasons), ask her to explain why.

Other Diseases Reported
(For which there are currently no genetic or screening tests for sire or dam)

  • Patellar luxation
  • Hyperuricosuria (Urate Stones) HUU
  • Spinocerebellar Ataxia (SCA)
  • Deafness
  • Late Onset Ataxia (LOA)
  • Neonatal Granuloprival Ataxia (NGA)

Ask the breeder about the medical history of the parents, grandparents and great grandparents. Consider carefully whether to purchase a puppy if some of these or other diseases are in the family line.

Ask about the breeder’s policy in cases of serious genetic diseases occurring to your puppy in later life. Good breeders will request to be informed of such events in order to improve future breeding decisions.

You are strongly advised to buy from a breeder who uses (or is prepared to use) the AWF Puppy Contract and Puppy Information Pack (PIP):

The breeder should also be familiar with the CFSG/DBRG Code of Practice for Dog Breeding
