# Genetic Testing for Dogs Explained: A Breeder Guide

> **Quick Summary:** A canine DNA test only checks specific gene variants, so a clean result says nothing about hips, hearts, knees, or eyes. Buyers should read each result as clear, carrier, or at-risk, and remember that carrier-to-carrier pairings give puppies a 25 percent chance of being at-risk. For crossbreeds like Havapoos and Cavapoos, the tested panel needs to cover both parent breeds, not just one. Sage Puppies documents DNA, OFA, and exam records for every litter so families can verify the full health picture before they buy.

A breeder hands you a one-page report and says the words *health tested*. Then a small puppy toddles across the floor, and you have about ninety seconds to decide what all of it means. That moment is the problem this guide solves.

Many buyers assume a **DNA test dogs** result is a clean bill of health. It is not. **Breeder genetic testing** covers only specific gene variants, and a report says nothing about hips, hearts, or knees unless a vet examined them. A **canine DNA testing** panel is one layer of proof, not the whole stack.

This guide walks you through reading a real report, telling DNA results apart from physical exams and parent screening, and asking the right questions for Havanese, Havapoo, and Cavapoo puppies, drawn from how we document health records for every Sage Puppies litter.

## What canine DNA testing can and cannot tell you

A DNA test dogs get today reads specific spots in their genes and reports what it finds. That sounds simple, but the result is narrower than many buyers expect. A report can tell you which variants a dog carries. It cannot promise the dog will stay healthy, and it cannot diagnose a sick dog on its own.

### Variant, predisposition, and diagnosis are three different things

A **variant** is a known change in a gene. A **predisposition** means that change raises the odds of a disease. A **diagnosis** means the dog is actually sick, and only a veterinarian can make that call. For example, the SOD1 mutation is described by the [AKC Canine Health Foundation](https://www.akcchf.org/breakthrough/genetic-test-for-degenerative-myelopathy/)
 as a major risk factor for degenerative myelopathy, not a certain outcome. UC Davis notes that [genetic results show risk](https://synergy.vetmed.ucdavis.edu/news-article-spring-2023/what-genetic-testing-can-and-cant-tell-you-about-your-pet)
, not a medical verdict. Treat an “at risk” result as a reason for monitoring, not a sentence.

### One disease can have different mutations in different breeds

This trips up many first-time readers. A disease’s name stays the same across breeds, but the underlying mutation often changes. Cornell’s canine health center explains that [many tests are breed-specific](https://www.vet.cornell.edu/departments-centers-and-institutes/riney-canine-health-center/canine-health-topics/benefits-canine-dna-testing)
, and a panel built for one breed may miss the variant that matters in another. That matters for crossbreeds like a Havapoo or Cavapoo, which inherit from two breed backgrounds. A clear result on the wrong panel proves little, so ask which mutations a test actually covers.

### Parentage testing is a separate use

DNA profiling also confirms which dog sired or whelped a litter. This has nothing to do with disease risk. When you review a breeder’s paperwork, parentage results sit apart from [parent screening and puppy health records](https://sagepuppies.com/genetic-health-tests-every-puppy-should-have/)
. Read each document for what it claims, and expect both to be available.

## How to read a dog’s DNA test results

A DNA test dogs report sorts each screened condition into one of three outcomes: clear, carrier, or at-risk. Once you know what each word means, the rest of the page falls into place.

### Clear, carrier, and at-risk explained

**Clear** means the dog has two normal copies of the gene, so it neither has the condition nor passes the mutation on. **Carrier** means one mutated copy and one normal copy. Carriers are usually healthy themselves, but they can pass the mutation to about half of their puppies. **At-risk** means two mutated copies (or one, for dominant conditions), so the dog may develop or pass on the disease. Cornell’s canine health center notes that puppies from a clear parent bred to a carrier can also be called clear by parentage, which is another phrase you may see. At-risk and carrier are not the same thing, and reading them as identical is the most common buyer mistake. When a lab flags at-risk, it means elevated risk, not a certain diagnosis, much like the SOD1 example above.

### Worked pairing example for a prospective litter

Say a dam is a carrier for a recessive condition and the sire is clear. Every puppy inherits one normal copy from the sire, so none will be at-risk. Statistically, half will be carriers and half will be clear. Breed two carriers instead, and each puppy has a 25 percent chance of being at-risk. That’s why pairing logic matters more than any single result. [Embark’s own guidance](https://help.embarkvet.com/hc/en-us/articles/11328997793819-What-does-At-Increased-Risk-or-Carrier-in-my-dog-s-health-results-mean)
 recommends avoiding at-risk pairings when you have the choice, and responsible programs follow that rule. You can ask any breeder to walk you through [how both parents were health tested](https://sagepuppies.com/5-questions-to-ask-about-health-tested-puppy-parents/)
 before you commit.

### No-call, inconclusive, and breed-not-applied results

Not every line in a report is a verdict. A **no-call** means the lab couldn’t read that marker, so it retests or lists no result. **Inconclusive** results need a second look or a different test. **Breed-not-applied** means the variant isn’t known to occur in your dog’s breed, so it carries little weight. Ask the breeder what each flagged line means rather than assuming the worst.

## What genetic tests a breeder should run before pairing a dam and sire

A responsible pairing starts with the tests each breed’s parent club recommends, then adds anything the actual ancestry calls for. Skip the first step and you may test for the wrong things. Skip the second and you may miss a variant hiding in a poodle or Cavalier line.

### Start from the current parent club and OFA requirements

Every recognized breed has a parent club that lists the health screens it wants before breeding. The [OFA’s breed-by-breed database](https://ofa.org/chic-programs/browse-by-breed/)
 shows those requirements, and a dog that completes them earns a CHIC listing, though that listing means the tests were done, not that every result passed. For the Havanese, the [breed club’s health guide](https://havaneseclubofamerica.org/health-issues-and-testing/)
 lists patellar luxation, cardiac exam, hearing, and hips among the core screens. A breeder should verify each parent’s results in a public database rather than take a screenshot on faith.

### Then add variants relevant to the actual ancestry

Purebred requirements are only the floor. For crosses like the Havapoo or Cavapoo, each parent brings a different set of risk variants, so a breeder should test each dog against both sides of the pairing. A Cavapoo sire, for example, needs the Cavalier-relevant checks, not just the poodle list. Multi-panel DNA tests cover dozens of variants at once, but a panel result should list which variants were actually included. “Screened” means nothing if the gene for a relevant condition was never tested.

### Confirm parentage and record everything

Good programs also run a parentage marker set, which confirms which sire produced which litter. Results should be permanently identified to the dog and kept with the puppy’s exam and clinical records. At Sage Puppies, for instance, parent records travel with each puppy file so buyers can see the full picture.

## Physical screening that no DNA swab can replace

A DNA report tells you which variants a dog carries. It says nothing about how the body actually developed. Hips, knees, and eyes can still fail in a dog with clean genetics, so breeders and vets check the physical structure itself.

### Hips, knees, and eyes are evaluated differently

Each joint and organ uses its own screening method. Hips are judged by X-ray, usually scored through OFA once a dog reaches two years old. Knees are checked by hand, because a vet can feel a loose kneecap, called *patellar luxation*, during a plain physical exam. Eyes need a board-certified ophthalmologist who looks inside the eye for inherited disease. In other words, three separate checks, three different skills, and one DNA swab covers none of them. The [OFA’s hip screening procedures](https://ofa.org/diseases/hip-dysplasia/hip-screening-procedures/)
 explain what a proper hip evaluation involves.

### PennHIP is about hips, not knees

PennHIP is a second hip method, not an all-joint test. It measures how loose the hip joints are using several X-ray views under sedation, and dogs can be evaluated as young as 16 weeks. Research summaries note it can detect laxity far earlier than standard scoring, though it still only speaks to hips ([NIH review](https://pmc.ncbi.nlm.nih.gov/articles/PMC2657530/)
). If a breeder cites PennHIP, ask what it covered.

### Keeping the puppy’s own record separate

Parent screening is not puppy health. Your puppy’s vet exam, vaccines, and deworming live in their own record, and it helps to know [how to read a puppy vet record](https://sagepuppies.com/how-to-read-a-puppy-vet-record-before-buying/)
 before pickup.

## What to ask a breeder to show you before you buy

A good breeder expects questions and has paperwork ready. Your job is to ask for the right documents, then read them yourself rather than taking claims on faith.

### Ask for the actual result, not the word tested

“Tested” means nothing without the result behind it. Ask to see the [OFA record](https://ofa.org)
 for each parent, which lists any hip, knee, eye, and cardiac evaluations, plus DNA test results by name. Then ask for the parent’s actual lab report for the conditions relevant to the breed. For a Havanese, that usually includes patellas, hearing, cardiac, and eyes. A written pedigree with registration numbers helps you verify that the dogs in the paperwork are the dogs you met.

### Red flags worth pausing over

Watch for vague answers like “the parents are healthy” with no records attached. Other warning signs: a breeder who only texts, refuses a video call, will not let you visit or meet the mother, or pressures you to place a deposit same-day. Also pause if a report shows two carriers bred together, since each puppy then has a 25 percent chance of being at-risk.

### A short question list to bring to the breeder

Family reviews puppy health records with breeder

- Which health screenings did each parent complete, and can I see the records?
- Can I meet the mother, at least by video?
- What happens if a puppy tests positive for a condition later?
- What does your health documentation include at pickup?
- May I speak with a family who bought a puppy from a past litter?

Honest breeders answer these without hesitation. At Sage Puppies, for example, every puppy goes home with documented exam records so families can see exactly what was checked and when.

## Genetic testing for cross-breeds: Havapoo and Cavapoo questions

Cross-breed reports raise a fair question: which breed’s list applies? The answer is both. A Havapoo puppy can inherit variants from the Havanese side, the Poodle side, or both, so the relevant panel is the union of the two parent breeds’ concerns.

### Build the list from both parents

For a Havapoo, that means combining Havanese screening (heart, hearing, and eye checks such as for [Poodle](https://embarkvet.com/pages/cavapoo)
 conditions like progressive retinal atrophy) with the Poodle panel. For a Cavapoo, the Cavalier side adds cardiac issues, including mitral valve disease, plus syringomyelia screening, alongside the Poodle list.

Ask a breeder which variants their panel covers and how results guide pairings. [Reputable breeders](https://www.petmd.com/dog/breeds/cavapoo)
 base health decisions on this testing rather than skipping it because cross-breeds “aren’t purebred.”

### Popularity brings its own questions

Havapoos and Cavapoos have surged in popularity, which means more breeders offering them, with varying testing rigor. Because they aren’t AKC-recognized, there’s no mandatory breed health requirement, so a breeder’s testing choices are voluntary.

Verify that the parents’ DNA reports are breed-relevant, not just generic. Ask to see certificates, and ask how [orthopedic and eye concerns](https://www.petmd.com/dog/breeds/cavapoo)
 on the non-Poodle side were screened. Solid answers here tell you more than a cute photo ever will.

## Records, registries, and how to verify them yourself

### What OFA and CHIC actually record

The Orthopedic Foundation for Animals (OFA) is a public database of health test results, and its advanced search lets you look up any dog by registered name, breed, or [OFA number](https://www.ofa.org/advanced-search/)
. Results include X-ray evaluations and DNA test outcomes. A **CHIC number** is different: it confirms a dog completed its breed’s required test list, and the [CHIC report](https://ofa.org/chic-programs/)
 lists each test, the dog’s age, and the result. It does not certify the results are good. A dog can hold a CHIC number while carrying risk variants, so read the individual entries, not just the number.

### Labs, reports, and how to ask good follow-up questions

A DNA report is only as strong as the lab behind it. Ask which lab ran the test, whether results came from a cheek swab the breeder collected or a vet-drawn sample, and whether the lab posts results to OFA directly. Then ask to see the actual report, with the parent’s name visible, not a summary screenshot. Good follow-ups: “Which variants were tested?”, “Were both parents tested?”, and “Can I see each report in full?” Honest breeders answer quickly and hand over paperwork without hesitation.

## Frequently Asked Questions

### Q1: What genetic tests should a breeder run before pairing a dam and sire?

Start with each parent breed’s club and OFA-required screens, then add DNA panels covering variants relevant to the dog’s actual ancestry. For Havapoos or Cavapoos, that means testing both breed backgrounds, plus a parentage marker set.

### Q2: How do I read a dog’s DNA test results as clear, carrier, or at-risk?

Clear means two normal copies, so nothing is passed on. Carrier means one mutated copy; the dog is usually healthy but can pass it on. At-risk means elevated disease risk, not a diagnosis.

### Q3: What health tests should I ask a breeder to show me before buying a puppy?

Ask for OFA records for hips, patellas, cardiac, hearing, and eye exams, plus the actual DNA lab reports with each parent’s name visible. Verify results in OFA’s public database yourself.

### Q4: Can two carrier parents ever be bred responsibly?

Generally no. Two carriers produce puppies with a 25 percent chance of being at-risk, so responsible programs pair carriers only with clears.

### Q5: Does a CHIC number mean the parents are healthy?

No. CHIC only confirms the required tests were completed. Read each individual result.

### Q6: Do DNA panels cover crossbreeds like Havapoos properly?

Only if the panel includes variants from both parent breeds, so ask which mutations were actually tested.

## Conclusion

A DNA report is one layer of proof, not the whole picture. Read each result as clear, carrier, or at-risk, and remember that at-risk means elevated odds, never a diagnosis. Pairing logic matters more than any single line: carriers bred to clears produce healthy litters, while two carriers do not. For Havanese, Havapoo, and Cavapoo puppies, testing should cover both sides of the ancestry, and DNA results sit apart from hip, knee, eye, cardiac, and hearing exams. Ask for the actual lab reports and OFA records, then read them yourself. Paperwork you can verify is worth more than the word *tested*.
