The Short Haired 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
All dogs [2] General canine population rate (Lund et al. 1999), not Collie-specific.
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
Confirmed 70-97% of Rough and Smooth Collies in the US and UK carry at least one copy of the NHEJ1 gene deletion that causes CEA (multiple molecular surveys); severity varies widely and most carriers show only mild changes.
An inherited eye malformation present from birth, ranging from mild choroidal thinning to retinal detachment and blindness. No treatment reverses it.
What is this?Hide
Confirmed OFA reports 2.8% dysplastic among evaluated Collies, one of the lowest rates of any OFA-tracked breed.
Malformed hip joint causing pain, limping, and progressive arthritis. Full profile →
Known risks
Well documented in the breed - but no study has counted how often.
What is this?Hide
Confirmed [3,4] MDR1 mutation is homozygous (affected) in 35% of US Collies and 48% of French Collies sampled (Neff et al. 2004, Pharmacogenetics; Mealey et al. 2001, AJVR). Smooth and Rough Collies share the same lineage and mutation.
A gene mutation that makes Collies dangerously sensitive to ivermectin, loperamide, and several other common drugs, causing neurologic toxicity at normal doses.
What is this?Hide
Breed study Dermatomyositis is a well-documented hereditary disease specifically described in Collies and Shetland Sheepdogs (Collie Health Foundation, multi-locus genetic studies), but no population-wide prevalence percentage has been published.
An inherited autoimmune disease attacking skin and muscle, usually appearing in puppies under 6 months as facial sores and hair loss.
What is this?Hide
Not measured A rare rcd2-type PRA has been reported in Collies, but no breed-specific prevalence study was found. Not to be confused with the much more common Collie Eye Anomaly, listed separately above.
Inherited retinal degeneration causing gradual blindness with no cure. Full profile →
What is this?Hide
Not measured Epilepsy is reported anecdotally in Collies, but no breed-specific incidence study was found.
Recurrent seizures requiring lifelong medication and monitoring. Full profile →
What is this?Hide
Not measured No Collie-specific prevalence data found.
Chronic skin inflammation causing persistent itching and repeated infections. 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.
