The Parson Russell 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
All dogs General canine obesity prevalence; no Parson Russell 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 →
What is this?Hide
All dogs All-dogs baseline skin disorder rate; no Parson Russell Terrier-specific breed effect confirmed.
Chronic skin inflammation causing persistent itching and repeated infections. Full profile →
What is this?Hide
All dogs All-dogs baseline diagnosed dental disease rate; a UK health survey of 209 Parson Russell Terriers found 29.19% affected by at least one condition and 70.81% unaffected, among the lowest-elevated-risk breeds overall (O'Neill et al. 2017, Canine Genetics and Epidemiology).

Known risks
Well documented in the breed - but no study has counted how often.

Breed study [2] A KCNJ10 gene mutation (c.627C>G), originally characterized in Jack Russell Terrier and later reconfirmed segregating in Parson Russell Terrier, was found at 22.1% homozygous and 28.6% heterozygous in a German cohort of 77 dogs (Gast et al. 2016, BMC Veterinary Research) - a single-country cohort figure, not a universal breed prevalence. Replaces a generic, unsupported heart murmur/MVD placeholder.
This breed carries a second, distinct, gene-confirmed ataxia disorder, shared with the related Jack Russell Terrier. Full profile →

Not measured A modest patellar luxation odds ratio (1.5) is documented for the related Jack Russell Terrier (O'Neill et al. 2016, Canine Genetics and Epidemiology, n=13,520 JRTs), but that study did not separately confirm Parson Russell Terrier, and an odds ratio is not the same as the 12% prevalence figure this replaces. OFA screening database: 0.6% of 532 submitted patella exams graded abnormal. Voluntary submissions - true population rate may differ.

Not measured No confirmed Parson Russell Terrier-specific cataract prevalence found.

Breed study [1,2] A missense mutation in the CAPN1 gene, autosomal recessive, causes spinocerebellar ataxia with onset 6-12 months, progressing to truncal sway and pelvic-limb hypermetria; affected dogs are typically euthanized by around age 2 due to poor quality of life. This disorder was first described and its causal mutation identified specifically in this breed (Forman, De Risio, Mellersh 2013, PLOS ONE). A German validation cohort (n=77 Parson Russell Terrier + 9 Jack Russell Terrier) found zero copies of this exact variant, suggesting regional/lineage variation or an additional causal variant (Gast et al. 2016, BMC Veterinary Research). Replaces an unsupported generic Legg-Calve-Perthes placeholder.
This breed is where this real, gene-confirmed neurological disease was first described and its causal mutation identified. Full profile →

Not measured No confirmed Parson Russell Terrier-specific hypothyroidism prevalence found.

Breed study [3] A CHRNE gene frameshift mutation, autosomal recessive, causes congenital myasthenic syndrome, confirmed segregating in both Jack Russell Terrier and Parson Russell Terrier; onset 5-10 weeks with exercise-induced weakness, often with megaesophagus, and most affected pups die within 1 year (Rinz et al. 2015, Neuromuscular Disorders - originally described in Jack Russell Terrier). No population prevalence percentage has been published. Replaces an unsupported generic epilepsy placeholder.
This breed shares a real, gene-confirmed, often-fatal neuromuscular disease with the closely related Jack Russell Terrier. 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
- How we grade evidence →

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.
