Sealyham Terrier

Lifestyle Needs

Sealyham Terrier

The Sealyham Terrier was once reputed to be a tough little hunter of vermin.  They are a versatile breed.  Some still work but many are pet dogs.  He’s a typical terrier by nature, so not suitable for someone looking for a lap dog. Sealyhams are strong, fast, energetic, lovable and fearless.  He needs regular exercise and mental stimulation. Frequent grooming is required to keep his coat clean and tangle free.

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

The UK Kennel Club breed average COI is 4.8% - See 'A Beginners Guide to COI'

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

111.13

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)

The Sealyham’s short legs do limit his ability to run and play.

BVA/KC Health Schemes: www.bva.co.uk/chs

  • Eye disease: Primary lens luxation (PLL) (annual testing) ; Total retinal dysplasia (TRD) (litter screening).
  • Hip Dysplasia (HD) breed 5 year mean score 11 (parents should be lower)

Estimated Breeding Values (EBVs) : No EBVs are currently available for this breed
www.thekennelclub.org.uk/about-ebvs

DNA Tests Available
DogWellNet and IPFD Harmonisation of Genetic Testing for Dogs (HGTD)
www.dogwellnet.com/breeds

  • Primary lens luxation (PLL)

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

  • Congenital deafness
  • Eye disease: Cataract; Glaucoma

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)

  • Keratoconjunctivitis sicca (‘Dry Eye’)

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):  www.puppycontract.org.uk

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