Everything I ask shepherd buyers to verify applies to giant breeds, only more urgently. A Great Dane or a Mastiff carries shepherd-level genetic risk under two or three times the body weight, grows to adult size on an accelerated clock, and has fewer screening generations behind it. The questions are the same; the tolerance for a wrong answer is smaller.
This article extends the screening conversation from shepherd breeds to the giant group: what is different about the risk, which resources walk through a specific breed, and the exact questions to put to a breeder before you choose a puppy.
Where can francophone owners read a breed-level walkthrough?
Breed-specific documentation is where general advice becomes usable, and giant-breed buyers are lucky to have it in several languages. For French-speaking owners, the Swiss guide on Great Dane hip dysplasia screening walks through the breed in contextualized detail: the FCI standard and its five recognized coats, the history of the breed, dysplasia screening and prevention for this giant, the gastric dilatation-volvulus emergency every Dane owner should understand, and a documented method for verifying a breeder from identity papers to contract.
Its method matches the discipline I recommend here: reference texts on one side, practices that vary by country on another, and decisions that belong to a professional clearly marked as such. The Great Dane Club of America's health resources cover the same breed from the North American side, including the health schemes its member breeders use.
Do giant breeds face different dysplasia risks than shepherds?
The mechanism is identical: a ball and socket that develop out of alignment under genetic predisposition and environmental pressure. What changes with size is the physics and the clock. A giant breed puppy may gain a kilogram a week during peak growth, loading immature joints that have less margin for error than a Shepherd's. Excess calories and mineral imbalance during that window do more damage per week of mistake.
The clinical picture also differs. Giant breeds present earlier and decline faster once symptomatic, because body mass multiplies the force through a compromised joint on every step. And where a senior Shepherd can often be managed comfortably for years, a giant breed with the same radiographic grade runs out of compensating muscle sooner. Screening before purchase matters more, not less, when the dog will weigh seventy kilograms.
What should buyers ask about hip scores before choosing a puppy?
Ask for the screening results of both parents, by registry, method, and date, and ask to see the documents rather than a summary. In North America that means OFA grades or PennHIP distraction indices; in Europe it means the national scheme letter grades issued under FCI-affiliated clubs. A result you cannot trace to a dated document is a claim, not a score.
Then widen the question. What are the hip results of grandparents, siblings, and earlier litters? Has the breeder ever produced a dysplastic dog, and what did they change afterward? A breeder who answers with data is running a program; a breeder who answers with reassurance is running a sales pitch. Our guide to hip dysplasia genetics explains why even two Excellent parents can produce an affected puppy, which is exactly why the family record matters more than any single certificate.
Finally, ask what happens if your puppy develops dysplasia. The answer reveals whether the breeder sees the sale as an endpoint or the start of a documented relationship. The same buyer-side discipline applies to the large working breeds between shepherds and giants; our piece on hip screening in large working dogs covers that middle ground.
Reading the risk correctly
None of this is an argument against giant breeds. It is an argument for entering them with open eyes. A screened, documented Great Dane puppy from a program that publishes its results is a reasonable decision. An unscreened puppy marketed on size and colour is a debt the dog will pay later. And when the choice is between a striking appearance and a documented score, the score wins every time; we make that case in detail in why health data outranks looks.
Screen the parents, verify the paperwork, keep the puppy lean through the growth window, and you have done what any buyer reasonably can. The rest is genetics and luck, which is why the part you control deserves this much attention.
Screening does not stop being useful because a dog is small. For at-risk breeds, the same logic applies: radiograph the hips under a recognized protocol, submit the images to a scoring body, and record the result rather than relying on a casual opinion. The practical difficulty is that small breeds are often screened less, so fewer reference data exist. If you want to see how a documented system handles this, including health checks and litter declarations, read Spitz health checks in France for the breeder questions that reveal real paperwork. Ask any breeder for the actual score, not a verbal assurance.
