Specific cover types
Hereditary and congenital cover under UK pet insurance
Last updated
In short
Most UK pet insurers cover hereditary and congenital conditions provided no symptoms were present before the policy started or during the waiting period. The catch is that many breed-specific risks (hip dysplasia, syringomyelia, brachycephalic obstructive airway syndrome) often produce subtle early signs that get noted by vets and turn into pre-existing exclusions. Insure on day one of ownership.
Key takeaways
- Hereditary and congenital conditions are usually covered if no symptoms predate the policy.
- Breeder pre-purchase exams that note minor abnormalities can trigger exclusions.
- Some insurers permanently exclude specific congenital defects (e.g. cherry eye in some breeds).
- Brachycephalic conditions are increasingly excluded by some insurers as a class.
- Day-one insurance from week 8 is the cleanest way to avoid hereditary-condition exclusions.
Hereditary and congenital conditions are responsible for a meaningful share of UK pet insurance claims, particularly in pedigree dogs and pedigree cats. This guide explains what’s covered, what’s increasingly being excluded, and how to protect cover for breed-specific risks.
Hereditary vs congenital: a quick definition
Hereditary conditions are genetically inherited from the parents. They may not present at birth but develop later. Examples: hip dysplasia, progressive retinal atrophy, syringomyelia in Cavaliers, hereditary cataracts.
Congenital conditions are present at birth, regardless of cause. Some are hereditary (passed on genetically), some are developmental (caused by problems during pregnancy). Examples: liver shunts, heart defects, cleft palate, undescended testicles.
UK pet insurance treats both categories the same way at quote time and at claim time, with one exception: a small number of insurers exclude specific named congenital conditions for specific breeds (e.g. cherry eye in Bulldogs, entropion in Sharpei).
The standard wording
Most UK pet insurance policies cover hereditary and congenital conditions provided:
- No signs or symptoms predate the policy start or waiting period. Same definition as any other pre-existing condition.
- No prior investigation or treatment. Including pre-purchase exams that flagged anything.
- The condition isn’t on a named-exclusion list. Some insurers list specific conditions for specific breeds at quote time.
If your puppy is healthy at policy start and the condition presents months or years later, it’s usually covered.
The signs-before-policy trap
Hereditary conditions often produce subtle early signs. A young puppy with very mild hip dysplasia might show occasional bunny-hopping or reluctance to climb stairs. A Cavalier puppy with early syringomyelia might scratch at the air. These signs go into the clinical record, and they can later be cited as evidence the condition predated the policy.
Two practical defences:
- Insure on day one of ownership so the policy precedes any vet visit.
- If a vet notes anything at all in the clinical record, consider whether to disclose it at quote time. Insurers respond to disclosure at quote stage by either (a) explicitly accepting the risk, (b) explicitly excluding it, or (c) declining to insure. All three are better than ambiguity at claim time.
What’s increasingly being excluded
UK insurers have tightened cover on a few categories in the last two to three years.
Brachycephalic obstructive airway syndrome (BOAS)
Surgery for BOAS in flat-faced breeds (French Bulldogs, English Bulldogs, Pugs, Boston Terriers, Boxers) costs £2,500 to £6,000. As Frenchie ownership has exploded, insurer claims data has driven a few brands to start excluding BOAS surgery for high-risk breeds at quote time.
Currently:
- Cover BOAS: ManyPets, Napo, Petplan Covered For Life, Agria, Waggel
- Cover with conditions: Animal Friends (subject to underwriting), Direct Line (high premiums for flat-faced breeds)
- Exclude or heavily restrict: A growing number of comparison-site brands
If you have a Frenchie, Bulldog, or Pug, this is the single biggest piece of small print to check.
Hip dysplasia in working breeds
Hip dysplasia is largely covered, but some insurers add inner limits or require the breeder’s hip score evidence at quote time. Labradors and German Shepherds are the most-affected breeds.
Syringomyelia in Cavaliers
Cavalier King Charles Spaniels with syringomyelia (a neurological condition) can run up £5,000+ in MRI and ongoing medication. Most UK insurers cover it, but a small number now exclude it as a named condition for the breed at quote time.
Cherry eye in specific breeds
A surgical condition in some breeds (Bulldogs, Beagles, Cocker Spaniels) where the third eyelid gland prolapses. Surgery is £400 to £1,200. Some insurers exclude it specifically for breeds where it’s very common.
Common congenital conditions that are usually covered
If no symptoms predate the policy, the following are usually covered:
- Liver shunt (portosystemic shunt) — surgery £3,500 to £6,000
- Heart defects (PDA, pulmonic stenosis, ventricular septal defect) — surgery £4,000 to £10,000+
- Megaesophagus — lifetime management £1,000 to £2,000/year
- Hydrocephalus — diagnostic and management costs vary widely
- Patellar luxation — surgery £2,000 to £4,000 per knee
The bilateral exclusion question (see cruciate cover) applies to several of these too, particularly patellar luxation.
What to ask the insurer at quote time
Five questions for any breed-prone owner:
- “Is my breed subject to any named exclusions on your standard policy?”
- “Does the policy cover BOAS surgery for [my breed]?”
- “Is hip dysplasia covered for [my breed], and is there an inner limit?”
- “What’s the bilateral exclusion wording for [my breed’s known bilateral conditions]?”
- “If my puppy’s pre-purchase exam noted [whatever], does that affect cover?”
Get the answers in writing. Frontline staff sometimes give answers that contradict the schedule, and only the schedule wins at claim time.
Breeds where this matters most
| Breed | Key hereditary/congenital risks |
|---|---|
| French Bulldog | BOAS, IVDD, allergies, cherry eye |
| English Bulldog | BOAS, hip dysplasia, cherry eye, skin |
| Pug | BOAS, eye conditions, allergies |
| German Shepherd | Hip and elbow dysplasia, degenerative myelopathy |
| Labrador | Hip and elbow dysplasia, hereditary cataracts |
| Cavalier King Charles Spaniel | Syringomyelia, mitral valve disease |
| Cocker Spaniel | Cherry eye, ear conditions, hereditary deafness |
| Maine Coon | HCM (heart), hip dysplasia |
| Persian cat | PKD (kidney), brachycephalic eye conditions |
For each of these breeds, day-one lifetime cover with the highest vet fee limit you can afford is the right starting point.
Summary
Hereditary and congenital conditions are usually covered by UK pet insurance if no symptoms predate the policy. The main risks are subtle early signs in clinical records that turn into pre-existing exclusions, and a tightening trend on brachycephalic conditions in flat-faced breeds.
Day-one insurance for a puppy or kitten is the cleanest defence. For breed-prone owners, ask explicitly about named exclusions before buying. See our breed-specific guides and the 2026 best UK pet insurance picks for the brands that handle hereditary risks best.

Are hereditary conditions covered by UK pet insurance?
Yes, by most standard policies, provided no symptoms or investigations predate the policy. Hip dysplasia, elbow dysplasia, and most genetic eye conditions are covered when they first present after the policy started.
Are congenital defects covered?
Usually yes, with the same condition: no signs before the policy started. Congenital heart defects, liver shunts, and similar are covered when first diagnosed during cover. The catch is that some defects produce mild signs from birth that the vet records, which can then count as pre-existing.
Is brachycephalic syndrome (BOAS) covered?
By most UK insurers, yes, but the wording is tightening. Some insurers now exclude BOAS surgery for high-risk breeds (Bulldogs, Frenchies, Pugs) at quote time. Read the schedule. ManyPets and Napo currently cover BOAS in flat-faced breeds; some other insurers don't.
What if my breeder's pre-purchase exam noted a minor abnormality?
Disclose it. The clinical record will be requested at any future relevant claim. If you disclose at quote time, the insurer will tell you whether it's an issue. If you don't and they find out later, the policy can be voided. ManyPets' historic-condition rule (clear for 2 years) sometimes helps if the abnormality fully resolved.
