Hip dysplasia is one of those conditions that can feel confusing and unfair: some dogs look “fine” for ages, others struggle early, and the internet is full of confident claims that don’t match real life.
The simplest accurate way to think about canine hip dysplasia is this: the hip joint doesn’t form as tightly as it should, which can allow looseness (laxity), partial slipping (subluxation), abnormal wear, and—over time—irreversible osteoarthritis (arthritis) and degenerative joint disease.
Most dogs with hip dysplasia are normal at birth, and the condition develops as they grow. It’s considered multifactorial, meaning genetics play a major role, but environment (like growth rate, nutrition and body weight) can influence how strongly it shows up in an individual dog.
This article is for owners who want practical, evidence-based guidance: what you can notice at home, what I’m looking for in an exam, how diagnosis actually works, and what treatment pathways exist—from conservative management through to surgery.


When does hip dysplasia show up?
Hip dysplasia can become evident during or just after the rapid growth phase. Joint laxity (the “loose hip” part) can be detectable as early as 12–24 weeks of age, and some vets can screen from around 12–16 weeks if there’s concern. Some dogs don’t show obvious signs until later, when arthritis has had time to build.
You’ll often see two common patterns:
- Young dogs: signs related to looseness/instability and early discomfort
- Adult/senior dogs: signs driven more by arthritis and chronic pain
Also: some dogs have significant radiographic changes but show minimal outward signs for a while, and others are clearly uncomfortable with relatively modest changes. Pain and function don’t always match an X-ray perfectly.
What causes hip dysplasia?
Genetics: the main driver
Hip dysplasia is widely recognised as an inherited condition. That doesn’t mean “one gene = one outcome”—it’s complex and polygenic—but it does mean family history and breed background matter.
Environment: the volume knob (growth rate, nutrition, body weight)
Even when genetics load the gun, environment can influence how loudly it fires. Research discussing hip dysplasia and related orthopaedic disease repeatedly points to factors like nutrition, growth rate and overall body weight as relevant influences on expression and progression.
Here’s what that means in real, owner-doable terms.
Calories and growth rate: “steady growth” beats “fast growth”
Puppies need enough energy to grow, but over-feeding and rapid growth can stress developing bones and joints. For large and giant breed puppies in particular, controlling calorie intake and monitoring growth rate is consistently emphasised as important, because rapid growth and excess body weight can worsen orthopaedic outcomes.
Practical take:
- Feed to a lean body condition, not to the “he looks hungry” standard
- Weigh your puppy regularly and adjust amounts as they grow (I can help you track this)
Minerals for bone development: balance matters (don’t DIY supplements)
Large/giant breed puppies have specific needs around calcium and phosphorus balance for skeletal development. A key issue is that puppies don’t regulate calcium absorption the same way adults do—so excess calcium can be a problem, not a bonus.
Practical take:
- Avoid adding calcium or “bone and joint powders” to a complete puppy diet unless I’ve specifically recommended it
- Choose a diet formulated for growth that already has the correct mineral balance
What I recommend in the real world (simple and safe)
If you want the lowest-drama, most reliable approach: pick a reputable, complete growth diet and stick with it.
For most puppies, Hill’s or Royal Canin puppy diets are my go-to recommendations. For large breed puppies, choose the large breed puppy varieties (they’re formulated with growth and skeletal development in mind).
Not sure if your puppy is likely to be “large breed”? With crossbreeds, it’s not always obvious, and getting it wrong can mean feeding the wrong type of diet during the main growth phase. If you’re on the fence, just get in touch — tell me your pup’s age, current weight, and breed mix (if you know it), and I’ll give you a straight answer on whether they should be managed like a large-breed grower.

Body weight: the lever you can control every day
If your puppy (or adult dog) is carrying extra weight, the hips are under extra load every single step. Keeping a dog lean is one of the most meaningful, controllable levers you have for joint comfort long-term.
Which dogs are at higher risk?

Breed risk: useful, but needs honest caveats
Some breeds are over-represented in hip dysplasia datasets, but it’s critical to be transparent about what those datasets actually represent.
In a large US hip-screening database (OFA records spanning 1970–2015), the proportion of dogs graded as dysplastic varied widely by breed. In that dataset, higher proportions of dysplastic hip ratings were reported in breeds including:
- Newfoundland (24.8%)
- Bloodhound (24.7%)
- American Staffordshire Terrier (24.4%)
- Bullmastiff (24.0%)
- Rottweiler (20.1%)
- German Shepherd Dog (18.9%)
- Golden Retriever (18.8%)
Lower proportions were reported in breeds including:
- German Shorthaired Pointer (3.9%)
- Flat-coated Retriever (3.7%)
- Belgian Tervuren (3.1%)
- Belgian Sheepdog (2.8%)
Limitation (important): these figures come from a voluntary screening database, not a random sample of all dogs. Owners and breeders may be more likely to submit dogs they expect to score well, and participation varies by breed. So these numbers are best read as “what showed up in screening submissions” rather than true population prevalence.
Aussie reality check: in Brisbane and surrounds, I commonly see hip and arthritis conversations come up in dogs like Labrador Retrievers, German Shepherd Dogs, Staffies (Staffordshire Bull Terriers and AmStaff types), and larger working breeds. With Kelpies and Australian Cattle Dogs, it’s often less about “classic hip dysplasia” and more about the broader category of hind-end pain, overuse injuries, and arthritis as they age — but the practical approach is similar: assess properly, keep them lean, build the right muscle, and manage pain early rather than toughing it out.
Mixed-breed dogs aren’t “immune”
Hip dysplasia affects dogs regardless of whether they’re purebred or mixed-breed. Breed can shift risk, but it doesn’t create a forcefield.
Signs you might notice at home
Owners usually don’t see “hip dysplasia”. You see a dog who’s subtly changing how they move, rest, or play.
Common owner-noticed signs can include:
- Stiffness, especially after rest
- Reluctance to jump, climb stairs, or get into the car
- “Bunny hopping” gait behind
- Reduced willingness to run, play, or go for longer walks
- Soreness after exercise
- Lameness that comes and goes
- Muscle loss over the hindquarters over time
- A dog who’s more irritable about being touched around the hips/back end
If your dog is showing any of these, it doesn’t automatically mean hip dysplasia—but it does mean it’s worth a proper assessment.
How I diagnose hip dysplasia (and why X-rays matter)
The short version
A hands-on exam can raise suspicion, but radiographs (X-rays) are the backbone of diagnosis and grading.
What the vet exam can tell us
In an exam I’m looking at things like:
- Gait and posture
- Pain response and range of motion
- Muscle symmetry
- Signs consistent with joint laxity
- Other causes of hind-end pain that can look similar
What X-rays can tell us
Radiographic schemes vary internationally, but they generally assess hip conformation and changes consistent with dysplasia and osteoarthritis.
The OFA system, for example, categorises hips as:
- Excellent, Good, Fair (considered non-dysplastic)
- Borderline
- Mild, Moderate, Severe dysplasia
Different systems may use different measurements and scoring approaches, but the goal is similar: evaluate hip structure and the presence/degree of degenerative change.
PennHIP vs OFA (owner-friendly explanation)
If you’ve heard these names and felt like you needed a decoder ring:
- OFA-style scoring is based on radiographic assessment categories
- PennHIP incorporates objective measures of hip laxity
Both are used to inform breeding decisions and risk assessment. What matters for you is not the acronym — it’s whether the imaging answers the practical questions: what’s going on, how painful is it likely to be, and what’s the best plan from here.
What treatment looks like (realistically)
There isn’t one magic fix. Treatment is usually about:
- reducing pain
- improving function
- slowing the arthritis snowball where possible
Weight management (often the biggest win)
If your dog is even slightly overweight, the hips are carrying extra load every single step. Keeping a dog lean is one of the most practical, evidence-aligned ways to reduce joint stress.
Exercise: keep moving, but don’t smash the joint
The goal is consistent, controlled activity that builds muscle without repeated high-impact strain.
Good options often include steady walks and structured strengthening. I’m cautious with repetitive high-impact stuff like constant ball throwing, hard stops and starts, slippery floors, and “weekend warrior” bursts.
Pain relief and anti-inflammatory medication
Many dogs benefit from veterinary-prescribed pain control and anti-inflammatory strategies. The exact plan depends on age, severity, other health conditions, and how the dog responds.
If you’re worried about long-term medication, that’s a normal concern. The practical approach is: we weigh quality of life, monitor response, and adjust thoughtfully—rather than leaving a dog sore because the idea of medication feels uncomfortable.
Supplements and supportive care
Some supplements are commonly used in arthritis management plans. The key is to treat them as supportive, not as a replacement for weight control, appropriate exercise, and pain management when needed.
Home modifications (quietly powerful)
Small changes can make a big difference:
- Non-slip rugs/runners
- Ramps for cars and steps
- Orthopaedic bedding
- Keeping nails trimmed for traction
- Blocking slippery areas during flare-ups
This is especially relevant for mobile vet clients: I can often spot environmental “pain triggers” in the home that don’t show up in a clinic consult.
Surgery (for the right dog, at the right time)
Surgical options exist for canine hip dysplasia, but they’re not one-size-fits-all. The biggest practical factor is timing: some procedures only make sense in a narrow age window (before arthritis is established), while others are used later as “salvage” or replacement options.
Juvenile Pubic Symphysiodesis (JPS)
JPS is an early-intervention procedure for puppies where the surgeon closes (fuses) part of the pubic growth plate. The goal is to change how the pelvis grows so the hip sockets end up covering the femoral heads better as the puppy matures. It’s aimed at reducing future subluxation and slowing the arthritis snowball.
When it can be performed (age): typically very early — most commonly quoted around 12–16 weeks of age (it’s a narrow window, and suitability depends on imaging and surgeon assessment).
Double Pelvic Osteotomy (DPO) / Triple Pelvic Osteotomy (TPO)
DPO/TPO are “hip-preservation” surgeries for young dogs. The pelvis is cut and rotated so the hip socket provides better coverage of the femoral head, improving stability and reducing abnormal wear. (TPO involves three cuts; DPO is a modified approach with two cuts — the intent is similar.) These procedures are generally for dogs that have hip laxity/subluxation but do not yet have significant osteoarthritis.
When it can be performed (age): usually in young dogs before arthritis is established, commonly around 6–10 months (timing is case-dependent and based on radiographs and growth stage).

Femoral Head and Neck Excision (FHO / Femoral Head Ostectomy)
FHO removes the femoral head and neck, eliminating bone-on-bone contact in a painful hip. The body forms a “false joint” (fibrous pseudo-joint). The aim is pain reduction rather than restoring a normal hip. Outcomes depend heavily on rehab and muscle mass; it often suits smaller/lighter dogs best, but can be used in other cases where appropriate.
When it can be performed (age): can be performed at a wide range of ages (puppy through adult), because it’s not reliant on a narrow growth window. It’s chosen when pain/function warrants it and other options aren’t suitable.

Total Hip Replacement (THR)
THR replaces the diseased hip joint with prosthetic components (a new femoral head/neck and a new acetabular cup). It’s typically considered for dogs with significant pain and dysfunction, often where arthritis is advanced or other options won’t give a good outcome. The goal is the most “normal-feeling” function possible compared with other salvage procedures.
When it can be performed (age): generally once the dog is fully grown / growth plates are closed (often ~12 months+, sometimes older depending on breed size and surgeon preference), and when the dog’s overall health and anatomy suit the procedure.

If surgery is on the table, the best next step is usually referral to an orthopaedic surgeon for imaging review and a tailored recommendation.
Can hip dysplasia be prevented?
You can’t guarantee prevention, but you can reduce risk and severity:
- Choose breeders who use recognised hip screening and make evidence-based breeding decisions
- Keep growing dogs at a healthy body condition—avoid rapid weight gain
- Feed an appropriate growth diet (and for large breeds, a large breed puppy formulation)
- Build fitness gradually; avoid high-impact “all gas, no brakes” exercise in young dogs
Long-term data suggests that selection using phenotypic (radiographic) screening can reduce disease liability over time, but improvement is breed-specific and depends on participation and selection intensity.
When to book a vet check (and when it’s urgent)
Book an assessment soon if you notice:
- persistent stiffness or lameness
- reluctance to jump or do stairs
- reduced activity or obvious discomfort after exercise
- hind-end weakness or muscle loss
Seek urgent care if:
- your dog can’t bear weight
- there’s sudden severe pain
- there’s a major mobility change over hours to a day
How a mobile vet visit can help (especially for anxious or sore dogs)
For dogs with painful joints, the clinic experience can make everything harder—slippery floors, stress, rushing, and a dog that’s already guarding a sore body.
An at-home consult lets me assess movement in a familiar environment, reduce stress, and build a practical plan that fits your dog’s real day-to-day life (floors, stairs, car access, bedding, routines).
If you’re in Brisbane, Ipswich, Logan, Moreton Bay or surrounding areas, I can assess your dog at home and talk you through the options clearly—no pressure, no rushing.
