The Kooikerhondje is athletic, graceful, and bred for the field. But sporting breeds carry specific health risks - hip problems, ear infections, and eye conditions are part of the working dog package.
Measured risks
How often they happen is backed by published studies.
What is this?Hide
Breed study [1] 23.6% (199 of 842 dogs) affected in a Dutch national screening program 1994-2011, with a female:male ratio of 1.62; prevalence fell from 28% to 19% over the study period after screening was tied into breeding selection (Wangdee et al. 2014, The Veterinary Journal). Replaces an unsupported generic hip dysplasia placeholder - no comparable hip dysplasia study or figure exists for this breed.
This breed has a real, high, dedicated screening-program-confirmed rate of this joint condition - far more significant than hip dysplasia in this breed. Full profile →
What is this?Hide
All dogs All-dogs baseline skin disorder rate; no Kooikerhondje-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; no Kooikerhondje-specific breed effect confirmed.
Periodontal disease affects over 80% of dogs by age 3. Bacteria from infected teeth enter the bloodstream, damaging heart, kidneys, and liver over time. Full profile →
What is this?Hide
All dogs General canine otitis externa baseline; no Kooikerhondje-specific breed effect confirmed.
Recurring ear infections requiring ongoing treatment and monitoring. Full profile →
Known risks
Well documented in the breed - but no study has counted how often.
What is this?Hide
Not measured The breed club describes hereditary eye disease as rare within the breed, without a quantified percentage; no PRA-specific study was found.
Inherited retinal degeneration causing gradual blindness with no cure. Full profile →
What is this?Hide
Not measured The breed club reports only 1-5 epilepsy cases per year (an absolute count, not a rate), which cannot be converted to a defensible prevalence percentage without knowing total population size.
Recurrent seizures. Medication Full profile →
What is this?Hide
Not measured No confirmed Kooikerhondje-specific hypothyroidism prevalence found.
Underactive thyroid. Lifelong medication Full profile →
What is this?Hide
Breed study [3] An IBA57 gene mutation (c.439C>T, p.R147W), autosomal recessive, causes hereditary necrotising myelopathy, with onset 3-15 months and progressive, fatal ataxia and paralysis (Frontiers in Genetics, 2023, PMC10425596; original clinical description 1993). The Dutch breed club states affected animals are no longer born within its population due to mandatory DNA testing since the mutation was identified. Replaces a generic, unsupported cancer placeholder with a real, historically breed-defining condition.
This breed carries a real, gene-confirmed, historically fatal spinal cord disease, now largely controlled through mandatory DNA testing. Full profile →

Breed study [2] An original screening of 717 dogs (356 puppies) found 19 probands plus additional affected dogs with this severe bleeding disorder (Slappendel, Beijer, van Leeuwen 1998, Veterinary Quarterly); a DNA test was later developed (van Oost, Versteeg, Slappendel 2004, Journal of Veterinary Internal Medicine). The Dutch breed club states no affected animals are currently born within its population due to mandatory testing. Replaces a generic, unsupported bloat/GDV placeholder with a real, historically breed-defining condition.
This breed carries a real, historically severe bleeding disorder, now essentially eradicated through mandatory DNA testing. 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.
