Sealyham Terrier

Lifestyle Needs

Sealyham Terrier

The Sealyham Terrier was once reputed to be a tough little hunter of vermin but is now, like so many other breeds, just a household pet. He’s a typical terrier by nature, so not suitable for someone looking for a lap dog. He needs regular exercise and mental stimulation. Also frequent grooming to keep his coat clean and tangle free.

Inbreeding Coefficient - COI
(Should be as low as possible)

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

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).

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/ctp

  • Primary lens luxation (PLL)
  • Degenerative Myleopathy (DM)
  • Factor V11 Deficiency

Availability of a DNA test does not mean that it is always necessary or even desirable for breeders to use this test. Good breeders will have followed the recommendations of the appropriate breed clubs, Kennel Club and/or other qualified experts.

Unofficial (Breed Club) 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. Some breeders will also agree to contribute towards medical costs or refund purchase price.

You are strongly advised to buy from a breeder who uses (or is prepared to use) the RSPCA / BVA AWF Puppy Contract and Puppy Information Pack (PIP):  www.puppycontract.org.uk

You are also advised to buy from a breeder who follows the Dog Breeding Reform Group’s (DBRG) Standard for Dog Breeding:
