Hip dysplasia and pet insurance: OFA screening, enrollment age, and what gets excluded

What the veterinary sources say the condition is

The American College of Veterinary Surgeons (ACVS) describes canine hip dysplasia as a condition that begins as a dog grows and causes instability, or a loose fit, of the hip joint. Over time that looseness leads to cartilage loss, scar tissue and bone spurs. The ACVS page names hereditary factors as the largest single risk factor, says rapid growth or weight gain can make it worse, and says it occurs most commonly in large-breed dogs. OFA's own page frames it the same way: the condition typically develops because the hip joint formed abnormally, and OFA adds that severity and the age at which lameness starts are hard to predict, with calorie intake and exercise level among the factors that can influence how bad it gets.

Two features of this condition matter more to an insurance reader than to a clinician. The first is that signs are inconsistent. The ACVS page says affected dogs may show symptoms at any stage of the disease and that many show no obvious signs at all. The signs it lists are lameness, reluctance to rise or jump, shifting weight toward the front legs, loss of muscle in the hind limbs and hip pain. A dog can therefore carry the condition for years before anyone writes "limping" in a record, and the first written note may come long after the joint began to change. The second is that the ACVS recommends early screening at roughly 10 to 16 weeks of age, which means a diagnostic record can exist in a puppy that has never limped.

Insurance wording, by contrast, turns on dates and records. A policy does not ask when the joint formed. It asks when a sign was first noticed by you or your veterinarian, and whether that date falls before the policy started or inside a waiting period. The rest of this guide is about that gap between biology and paperwork.

OFA rates for the breeds this site profiles

OFA runs a voluntary registry. A veterinarian takes the radiographs and sends them for grading, and OFA uses seven categories: excellent, good and fair are within normal limits, while borderline, mild, moderate and severe are considered abnormal. Its disease statistics page publishes the share of evaluated dogs in each breed that were rated dysplastic. The table below collects the rows that appear on this site's breed profiles, ordered from the highest rate to the lowest, with the number of evaluations behind each. The figures are the ones printed on those profiles after the OFA statistics page was read on October 22, 2026; they were not re-read for this guide.

Source: Orthopedic Foundation for Animals, disease statistics by breed, https://ofa.org/diseases/disease-statistics/, read October 22, 2026 and carried onto this site's breed profiles. These are dogs whose owners submitted films. OFA's hip page says dysplastic grades are closed to the public unless the owner opts in to the open database, so the published counts describe screened dogs, not every dog of the breed.

Three readings of the table are fair and one is not. It is fair to say that rates differ enormously between breeds, that the highest rates sit in heavy or stocky breeds, and that a Labrador's 11.3 percent comes from a far larger sample than a Saint Bernard's 49.9 percent. It is also fair to say that the Doberman and Great Dane rows show a large breed is not automatically a high-rate breed. What the table cannot tell you is the chance that your own dog develops the condition. Submission is voluntary, breeders may choose which dogs to submit, and the numbers pool decades of dogs. Treat them as a reason to read the hip clause, not as a forecast.

The sample-size column also explains why some breed profiles on this site lean on the condition and others barely mention it. If you own one of the breeds near the top, the rest of this guide describes the claim you are most likely to meet. If you own a breed near the bottom, the same rules still apply, but other conditions on its profile probably decide the policy.

Screening creates a record, and the record is what an insurer reads

OFA offers preliminary evaluations for dogs between 4 and 23 months old (OFA hip page, read October 22, 2026). Early screening is a breeding and management tool, and many owners do it. For a buyer of insurance it has a side effect. Whatever the film shows becomes part of the dog's veterinary history, and the NAIC Pet Insurance Model Act defines a pre-existing condition by reference to veterinary advice, treatment or signs from verifiable sources before the effective date or during a waiting period (Section 3F, read October 22, 2026).

That does not mean screening is a mistake. A normal result is a clean record in writing, and an insurer reading a file with an excellent or good rating has nothing to exclude. The practical lesson is about sequence. If you plan to screen a young dog and you also plan to buy a policy, the policy should usually start first, so the waiting period has run before any abnormal finding is written down. A dog that is screened on Monday and insured on Friday has an abnormal film in the record that predates the policy.

The same logic covers the quieter records. A visit note that says the dog was stiff after a long walk, a groomer's comment passed on to the clinic, or an electronic record that mentions a gait change can each be read as a sign. The Model Act puts the burden on the insurer to prove that a pre-existing exclusion applies (Section 5A), but proof is easier when the note is plain. Ask your clinic for the full record before you enroll, read it as an insurer would, and consult the pre-existing conditions guide on how a borderline note is treated.

The treatment paths and the invoices they produce

The ACVS page describes several treatment paths, chosen by the dog's age, size and degree of joint damage. Each one produces a different invoice and may raise a different coverage question. No dollar amounts are printed in the table. The worked example further down uses labelled illustrative bill totals instead.

Treatment paths from the ACVS Canine Hip Dysplasia owner page, https://www.acvs.org/small-animal/canine-hip-dysplasia, read October 22, 2026. The invoice and clause columns are CoverMyBreed summaries for insurance education. Treatment decisions belong to your veterinarian.

Two things stand out from the table. First, the youngest paths happen when a dog is barely old enough to have cleared a waiting period, which is why enrollment age matters so much for this particular condition. Second, the oldest dogs on the medical-management path produce small invoices that repeat for years, so the question there is renewal behavior rather than a single large payout. The deductible and limits guide explains how an annual deductible repeats on a condition that never ends, and the claim payout simulator lets you run your own settings through it. For hydrotherapy and other maintenance sessions that run year after year, the physical therapy coverage guide works out how quickly an annual rehab sublimit runs out on an open-ended course. For the monthly arthritis injection that can follow on the medical-management path, the Librela arthritis insurance guide prices twelve months by label weight band and shows how a dysplasia note already in the record can pull the later arthritis under the same exclusion.

Seven insurer documents, read for the hip dysplasia clause

The insurer directory on this site records what each company's official pages and sample policy state, each with its verified date. Seven of the 19 records name hip dysplasia explicitly. The others either do not mention it or treat it as one of the general hereditary or orthopedic conditions, so their rows are left out rather than guessed. The list runs in directory order and is not a ranking. Sample policies are state forms, and several are years old, so the sentence in your own policy governs.

Read as a set, the rows show five different mechanisms behind the same dysplasia sentence: an optional add-on (AKC, PetPartners), a hard enrollment-age condition (Healthy Paws), a long orthopedic wait (Embrace and Fetch), a blanket look-back for signs (Trupanion) and a bilateral or chronic listing (Odie). They do not map to one another. A dog enrolled at three years with a clean record could be fully covered under one wording, covered only after a 12-month wait under another, and not covered at all under a third unless a paid endorsement is added. That is the reason this guide asks you to compare the clause and not the headline price.

The NAIC Model Act sets a ceiling for states that adopt it. Its Section 3D lists hip dysplasia among the orthopedic conditions, and Section 5B caps waiting periods for illnesses and non-accident orthopedic conditions at 30 days, with a required exam-waiver route. Where a state has not enacted that language, an insurer's longer special wait can stand. The Model Act page on the NAIC site does not publish a current count of adopting states, so this guide does not either; your state insurance department can tell you what applies where you live.

Where your dog is now, and what that means for the clause

Because the rules hinge on dates, the useful question is where a dog sits on the timeline today. The rows below describe typical positions and what to check. They are not advice about any individual animal.

The second hip, and why bilateral wording matters here

Hip dysplasia is usually thought of as a joint condition, so a second affected hip is no surprise. Insurance forms handle it with bilateral clauses. Embrace's FAQ uses hip dysplasia and cruciate tears as its examples of a bilateral condition, and Odie lists hip dysplasia on its bilateral list. The AKC sample defines a bilateral condition as one that affects both sides of the body and says a condition that presented on one side before coverage is pre-existing on the other side too.

The cruciate ligament guide works a two-knee example under three different wordings of the clause, and the same three readings apply to hips, so that example is not repeated here. See the cruciate ligament tear guide for the arithmetic, and the hereditary and bilateral exclusions explainer for the wording to look for. The hip-specific point is timing. If the first hip is operated on while the dog is insured and covered, the second hip is normally covered too, because the condition began after the policy. If the first hip was noted before coverage, the second hip is the clause that decides whether the policy pays anything.

Large and giant breeds raise another issue. Their conditions tend to stack, so a dog with hips on its record may also have elbows or knees on it. The large and giant breeds guide looks at how a policy's annual limit holds up when several orthopedic conditions arrive in the same year.

Questions to put in writing before you buy for a hip-prone breed

Ask these in writing, keep the replies with the policy, and ask for a section number when an answer refers to "the policy".

1. Is hip dysplasia covered in the base plan, an optional endorsement, or not at all?
2. Is there an enrollment-age limit for hip dysplasia cover, and does it count from the effective date?
3. What is the waiting period for orthopedic conditions, and how can a vet exam shorten it?
4. If hip dysplasia is diagnosed while I am insured, will it stay covered at every renewal without a new wait?
5. If one hip is covered, is the other hip treated as the same condition or as a new one, and does the deductible apply again?
6. Are rehabilitation, prescriptions for joint pain, and recheck imaging covered as part of an orthopedic claim?
7. Are secondary conditions, such as arthritis, covered if hip dysplasia itself was excluded?

Collect the answers and compare them in the line-by-line quote comparison method, so a lower premium is weighed against a narrower clause instead of being mistaken for a saving.

Before you request a quote

Open the profile for your breed and note which orthopedic conditions it names, then ask your clinic for a copy of the record so you know what an insurer would read. The new puppy guide covers enrollment timing for dogs in their first year, and the waiting periods guide shows the clocks you will be counting. For other conditions driving a large-breed premium, return to the conditions hub. A published breed anchor is a sample and not a quote, so get a live quote before deciding.
