The Border Collie is intelligent, driven, and tireless. But herding breeds carry genetic risks - hip dysplasia, eye diseases, and epilepsy are common. An active dog needs an active health budget.
Measured risks
How often they happen is backed by published studies.
What is this?Hide
Breed study [2] 29.6% carrier / 1.5% affected homozygotes, NHEJ1 mutation, Italian cohort n=334 (Marelli et al. 2022, Vet Rec Open). Carrier frequency, not clinical disease rate; varies by population.
An inherited eye defect from the classic "Collie" gene family, present at lower rates in Border Collies than Rough/Smooth Collies.

All dogs All-dogs baseline skin disorder rate; no Border Collie-specific breed effect confirmed in available literature.
Chronic skin inflammation causing persistent itching and repeated infections. Full profile →
What is this?Hide
All dogs [4] All-dogs baseline diagnosed dental disease rate (O'Neill et al. 2021, JSAP); no Border Collie-specific breed effect confirmed.
Periodontal disease is diagnosed in 12.5% of dogs in a year, and prospective exams that check every tooth find it in 44-64%. Bacteria from infected teeth enter the bloodstream, damaging heart, kidneys, and liver over time. Full profile →

All dogs OFA registry dysplastic rate 1974-2015 (10.8%, improving to 8.4% for dogs born 2011-2015). Voluntary breeder-submitted screening data, likely underestimates true population prevalence.
Malformed hip joint causing pain, limping, and progressive arthritis. Full profile →

All dogs [3] All-dogs baseline (Kearsley-Fleet et al. 2013, Vet Record). Border Collie is not named among breeds with elevated epilepsy odds in this or other epidemiology studies found.
Recurrent seizures requiring lifelong medication and monitoring. Full profile →
Known risks
Well documented in the breed - but no study has counted how often.
What is this?Hide
Not measured No confirmed breed-specific prevalence or odds ratio found for Border Collie. OFA thyroid screening: 4.3% of 326 panels abnormal (mostly compensated autoimmune thyroiditis - antibodies that often progress to hypothyroidism; 0.6% overt disease). Voluntary submissions - true population rate may differ.

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.
