Group 9 · Companion dogs
Boston Terrier
The Boston Terrier is a cheerful, compact American companion dog with tuxedo markings and a friendly nature. It is playful, clever and suits city life. The breeding programme of Dierenwelzijn Vlaanderen also pays attention to BOAS and the breathing of the parent dogs.
Health
These examinations come from the official breeding programme for the breed Boston Terrier by Dierenwelzijn Vlaanderen (Animal Welfare Flanders). They apply to the puppies’ parents.
In short
Both parents must have 2 examinations:
- 2 DNA tests
The breeding programme also recommends 5 further examinations.
A sample for DNA tests can be taken either with a mouth swab or by a blood sample. To carry out the examinations, the breeder uses a vet or a laboratory. For each examination below, you can see from what age and how often it must be done. Ask the breeder for the results of both parent dogs.

A breeding programme reduces the risk of hereditary conditions, but does not offer a 100% health guarantee.

Considerations when buying
According to the breeding programme approved by Dierenwelzijn Vlaanderen, these examinations must be carried out on both parent dogs: Canine multifocal retinopathy 1 (CMR1) and Degenerative myelopathy (DM). The breeding programme also lists these recommended examinations: Craniomandibular osteopathy (CMO), Patellar luxation (PT), Progressive retinal atrophy – cone-rod dystrophy 4 (cord1-PRA/crd4), Von Willebrand disease type 1 (VWF1) and Eye disorders. According to the breeding programme, BOAS is a hereditary condition for which no generally recognised scientific test is currently available. Dogs with severe breathing problems, too short a stop and narrow nostrils (stenotic nares), diagnosed by a vet, are not used for breeding. A puppy with a Flemish pedigree comes from parent dogs bred according to this breeding programme. Ask for the results of both parent dogs and compare them with the overview above. A Boston Terrier needs moderate exercise: a few walks a day and playing together are enough. In warm weather, plan walks for the cooler parts of the day. Its short coat is easy to look after.
Questions for the breeder
- Have both parent dogs undergone all the mandatory examinations in the breeding programme, and may I see the results?
- Is the general eye examination of both parent dogs still valid? According to the breeding programme: Valid for 2 years.
- Will the puppy receive a Flemish pedigree from a recognised breed registry association?
- How are the puppies socialised before they go to their new home?
Breed-specific challenges
The Boston Terrier is cheerful, people-oriented and clever, and enjoys short, playful training sessions. Do not go for the shortest possible muzzle, but for a breeder who has the examinations of the breeding programme carried out and is honest about the breathing of the parent dogs.
