English Toy Terrier
The English Toy Terrier is small in size, slim and lightweight. He makes an ideal companion dog, is generally non-aggressive and full of charm. He is happy in most home environments and like all dogs needs daily exercise. His short, glossy coat needs grooming no more than once a week.
Inbreeding Coefficient - COI
(Should be as low as possible)
The UK Kennel Club breed average COI is 11.1% - see 'A Beginners Guide to COI'
Effective Population Size - EPS131.6
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.

DNA Tests Available
DogWellNet and IPFD Harmonisation of Genetic Testing for Dogs (HGTD)
- Xanthinuria Type 2A

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
- Patellar luxation
- BAER testing
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)
- Demodectic mange
- Legg-Calve-Perthes disease
- Heat stress
- Eye disease: glaucoma, lens luxation, cataract
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
