The Norwich Terrier is tough, spirited, and full of energy. But terrier breeds face their own health challenges - knee problems, skin allergies, and dental disease can add up fast.
Measured risks
How often they happen is backed by published studies.
What is this?Hide
Breed study [1] 65.8% showed clinical signs (mild to severe) among 401 dogs screened at a breed-club health clinic; caused by an ADAMTS3 risk variant (32.9% homozygous, 48.6% heterozygous, allele frequency 0.57) (Marchant et al. 2019, PLOS Genetics). Screened, self-selected population - flag selection bias. Only 12 Norfolk Terriers were screened in the same study, too few to draw conclusions for that breed.

All dogs General canine obesity prevalence; no Norwich Terrier-specific breed effect confirmed.
Up to 40% of adult dogs are overweight. Obesity accelerates joint deterioration, increases cardiac load, and shortens life expectancy by 1-2 years. Full profile →

How we know these numbers
- Confirmed = measured or gene-confirmed specifically in this breed
- Breed study = scientists counted it in this exact breed
- Body type = comes from the dog's build - size, skull, skin
- Genetic risk = the gene is proven, the odds are not
- All dogs = an average for all dogs, not this breed
- Not measured = nobody has counted it yet

My mother-in-law's boxer. Problem. $1,200 in tests, no answers. Another vet solved it with $8 pills. When you're scared, you'll pay anything - and some vets price accordingly. So I built what I couldn't find: real costs, real exclusions, plain language. Not selling policies.
