Early Signs of Hip Dysplasia β The Short Answer
The earliest signs of hip dysplasia in dogs are often subtle β a slight reluctance to jump, a brief stiffness after rest that resolves quickly, or a marginally wider stance in the rear β and they can appear as early as 4β6 months of age in large breed puppies, months before a definitive diagnosis is possible on radiograph. The most recognised signs β bunny-hop gait, difficulty rising, obvious rear-end weakness β typically appear later, after the condition has been developing for months. Catching hip dysplasia early means knowing what to look for before the clinical signs are obvious, and bringing specific observations to your vet rather than waiting until the dog is visibly lame. This guide covers all 10 signs, in the order they typically appear.
10 Signs of Hip Dysplasia in Dogs
Post-rest stiffness that resolves quickly
One of the earliest and most frequently missed signs. A dog with early hip dysplasia will often show stiffness in the hindquarters for the first minute or two after rising from sleep or a rest period β then appear to "walk it off" and move normally. Because the stiffness resolves quickly, owners often dismiss it as normal puppy clumsiness or cold-weather stiffness. In a large breed puppy between 4 and 12 months, any consistent post-rest hind-end stiffness warrants observation and documentation β photograph or video the first 30 seconds of movement after rest for your vet.
Reluctance to jump or use stairs
A previously enthusiastic jumper who becomes hesitant to jump onto furniture, into a car, or up stairs is signalling that the loaded hip extension required for jumping has become uncomfortable. This often appears before any obvious lameness β the dog modifies behaviour to avoid pain rather than displaying overt distress. Watch for: pausing before jumping, taking stairs more slowly than previously, choosing not to jump when an obvious opportunity presents itself (a favourite sofa or a car they normally run to).
Bunny-hop rear gait
The bunny hop β bringing both hind legs forward simultaneously rather than alternating β is the most widely recognised sign of hip dysplasia. It is particularly visible when the dog is running at speed. The dog adopts this gait to reduce hip joint loading by distributing propulsion across both hind legs simultaneously rather than the full hip extension of the normal alternating stride. Watch from directly behind the dog at a free run on open ground: normal gait alternates left-right-left; a bunny hop moves both rear legs together.
Narrow or swaying rear stance
At rest and during slow movement, dogs with hip dysplasia may carry their rear legs abnormally close together (narrow-based stance) to reduce hip abduction stress, or may display a side-to-side swaying ("rolling") motion in the hindquarters during walking. The sway is most visible from behind at a slow walk β the hips move more laterally than in a normal dog. This compensatory movement pattern is a response to joint laxity (looseness) in the hip socket that allows the femoral head to shift during weight-bearing.
Shortened rear stride
Dogs with hip pain instinctively shorten their rear stride to reduce the range of hip joint motion required per step. This is visible as a reduced reach of the hind legs compared to the front legs during walking β the dog's rear legs appear to be "holding back" relative to the front. A useful comparison: watch the dog walk from the side and observe whether the rear paw placement matches or falls well short of the front paw placement on the same side. A significant shortfall in a young large breed dog is a meaningful observation.
Difficulty rising from lying down
The motion of rising from a fully rested position requires significant hip extension and load transfer through the pelvis. Dogs with hip dysplasia often show this as the first obviously effortful daily activity β taking multiple attempts to rise, using front legs to "pull" themselves up rather than pushing off with the rear, or vocalising during the effort in more severe cases. Difficulty rising is often more pronounced after prolonged rest (overnight) than after shorter naps.
Exercise intolerance β tiring earlier than expected
A dog that consistently tires earlier than peers of the same age and breed during play or walks β lying down during a session that previously caused no fatigue β may be pacing itself to manage hip discomfort rather than genuinely fatigued. This sign is particularly easy to miss in puppies, where variations in energy level are common and often attributed to normal puppy behaviour. The key indicator is consistency: a pattern of earlier-than-expected fatigue across multiple sessions, not a single low-energy day.
Muscle mass asymmetry β one side wasting faster
Dogs with unilateral (one-sided) or bilateral hip dysplasia where one hip is more affected will unconsciously weight-shift to the less painful side. Over weeks and months, the less-used side develops visible muscle atrophy (wasting) compared to the more-used side. This is most visible in the thigh muscles of the hindquarters β run a hand along both rear thighs and compare the muscle bulk on each side. Asymmetric hind-end muscle mass in a young large breed dog is a specific clinical observation worth reporting to your vet.
Personality or behaviour changes β reduced play drive
Pain changes behaviour. A dog that was previously eager to play, run, and engage but has gradually become more reluctant, irritable when the rear end is touched, or less interested in initiating play may be modifying its behaviour in response to hip discomfort. This sign is highly non-specific β many conditions and circumstances can affect play drive β but combined with any of the physical signs above, it provides an important behavioural context. A previously enthusiastic dog becoming specifically reluctant about activities that load the hind end is a meaningful pattern.
Audible clicking or popping from the hip
Joint crepitus β the clicking, popping, or grinding sound from the hip joint β can sometimes be heard or felt during passive manipulation of the hip (a movement your vet will perform) or occasionally during normal movement. It indicates irregular contact between joint surfaces and is a significant clinical sign when present. Owners rarely hear it spontaneously during normal movement, but it is a common finding during veterinary examination of dogs with moderate-to-advanced hip dysplasia.
How Signs Appear by Age
Earliest window β subtle signs only
Post-rest stiffness (resolves within 1β2 minutes), occasional reluctance to jump, slightly wide rear stance at rest. These signs are easily missed or attributed to normal puppy development. PennHIP evaluation (the only validated radiographic method before 16 weeks) can identify joint laxity risk as early as 16 weeks in specialist hands.
Growing load β signs become more consistent
As the puppy adds weight rapidly, joint laxity produces more consistent symptoms. Bunny-hop gait becomes visible during running, reluctance to use stairs is more pronounced, and difficulty rising after rest is more obvious. This is the window when most large breed dog owners first bring hip concerns to their vet. OFA hip evaluation is not valid before 24 months for official grading, but preliminary radiographs can be taken from 12 months.
Young adult β established pattern
Signs are now consistent and multi-session. Muscle asymmetry may be visible. Exercise intolerance is established. The dog has developed compensatory movement patterns β shortened rear stride, weight shift to front limbs β that experienced handlers can identify from a distance. OFA evaluation at 24 months provides the definitive adult radiographic picture.
Early adult β degenerative changes begin
Secondary osteoarthritis develops in the dysplastic joint, adding an inflammatory component to the mechanical dysfunction. Signs that were previously activity-related may become present at rest. This phase is where effective management in the growth window pays dividends β dogs with well-managed hip dysplasia enter this phase with better joint architecture and slower OA progression than those who were not managed during the growth window.
Vets cannot observe your dog every day. When you notice any of the signs above β even a single episode of post-rest stiffness or a single bunny-hop stride β write it down with the date, duration, and circumstances. A log of specific observations over 2β4 weeks is far more useful in a veterinary consultation than "I think he's been a bit stiff sometimes." Video clips of gait abnormalities, recorded from behind and from the side at a walk and trot, are equally valuable β most smartphones capture this clearly on a flat surface.

Take the Quiz βSigns That Are Easy to Miss
Several of the signs above are frequently misattributed or overlooked entirely. The three most commonly missed:
Post-rest stiffness misread as "cold stiffness"
Owners of large breed dogs in cooler climates often attribute post-rest stiffness to cold floors or cold weather β "he always stiffens up in winter." True environmental stiffness affects all four limbs relatively equally and resolves once the dog has warmed up. Hip dysplasia-related stiffness is disproportionately rear-end and resolves with movement regardless of temperature. Filming the first 30 seconds of movement across different weather conditions usually reveals whether the stiffness pattern is truly environmental or consistently present.
Bunny hop dismissed as "how this dog runs"
Owners who have never owned a large breed dog before sometimes accept the bunny-hop gait as a breed or individual characteristic β "she just runs like that." A bunny-hop rear gait is always a clinical observation. It is not normal for any dog of any breed. If you observe it consistently and have not yet raised it with your vet, raise it at your next appointment.
Exercise intolerance attributed to laziness
A young large breed dog that sits or lies down during play sessions β particularly one that was previously high-energy β is sometimes labelled as a "calm" or "lazy" temperament. Pain is the first differential for an unexplained reduction in activity drive in a breed that was previously motivated to play. If the pattern correlates with physical activity (the dog tires specifically during runs or play that loads the hind end), it is worth noting.
When to See Your Vet
Book a veterinary appointment promptly if your dog shows:
- Any visible lameness β weight-bearing reluctance, limping, three-legged walking at any point
- Consistent bunny-hop rear gait during running (even if the dog appears otherwise comfortable)
- Vocalisation or yelping during normal movement, handling, or rising
- Visible muscle asymmetry between the two rear thighs
- Post-rest stiffness that has been present for more than two weeks
- Any combination of two or more of the 10 signs above occurring in the same dog over the same time period
Overt lameness β visible limping or weight-bearing reluctance β is a late sign of hip dysplasia. By the time a dog is visibly lame, the condition has typically been developing for months. The earlier hip dysplasia is identified, the more management options are available and the more effective growth-window interventions (exercise management, weight management, supplementation) can be. Waiting until lameness is obvious means missing the window where the most proactive interventions are possible.
What to Do If You Suspect Hip Dysplasia
- Bring your observation log to the vet β specific, dated observations of gait, stiffness duration, and reluctance behaviours are more actionable than general concerns.
- Request a physical hip examination β your vet will perform an Ortolani test and hip range-of-motion assessment. These manual tests can identify joint laxity and discomfort before radiographic changes are visible.
- Ask about PennHIP evaluation β for puppies under 24 months, PennHIP (performed from 16 weeks) provides the only validated measure of hip joint laxity risk. It predicts OA development risk more accurately than the standard OFA hip-extended view in young dogs.
- Manage body weight β every extra kilogram of body weight increases the mechanical load on the hip joint. Keeping a growing large breed dog lean throughout the growth window is one of the most evidence-based interventions for hip dysplasia management.
- Start joint supplementation during the growth window β from 8 months through confirmed plate closure, MoveGuard Growth provides nutritional support for developing joint tissue. See: When Should You Start Giving Your Puppy a Joint Supplement?
Can Hip Dysplasia Be Prevented?
Hip dysplasia has a significant genetic component β the baseline predisposition is inherited. A dog from two OFA-evaluated parents with excellent hip scores has meaningfully lower hip dysplasia risk than a dog from unevaluated parents or parents with fair or poor scores. But genetics sets a floor, not a ceiling β environmental factors during the growth window significantly influence how a genetic predisposition expresses itself clinically. See: What Is Canine Hip Dysplasia? Causes, Symptoms, Stages and Treatment.
The environmental factors with the strongest evidence for hip dysplasia outcome:
- Growth rate β excess caloric intake that accelerates growth rate worsens hip dysplasia expression. Large breed puppy food with controlled calcium (0.7β1.2% DM) and appropriate caloric density is not optional for breeds at risk.
- Body weight β lean body condition throughout the growth window and into adult life reduces mechanical hip joint loading. Every study on hip dysplasia outcome consistently shows worse clinical severity in heavier dogs.
- Exercise type and intensity β high-impact repetitive exercise during the growth window worsens joint laxity outcomes. Controlled exercise and avoidance of jumping and sustained running during the growth window reduces developmental joint stress.
Hip dysplasia cannot be eliminated by management alone if the genetic predisposition is significant β but the severity of clinical disease, the age of onset of osteoarthritis, and the quality of the dog's working life are all meaningfully influenced by what happens during the growth window. Owners who recognise the early signs, act promptly, and manage the growth window proactively give their dogs the best possible outcome regardless of genetic baseline.

The earliest signs are often post-rest stiffness that resolves quickly within a minute or two of moving, reluctance to jump or use stairs, and a slightly swaying or narrow rear stance. These appear in large breed puppies as early as 4β6 months and are frequently missed or misattributed. The more obvious signs β bunny-hop gait, difficulty rising, and visible lameness β typically appear later, after the condition has been developing for months.
Definitive diagnosis requires veterinary examination and radiography β hip dysplasia cannot be confirmed by observation alone. However, consistent patterns of the signs described in this article are meaningful indicators that warrant a veterinary assessment: post-rest stiffness, bunny-hop rear gait, reluctance to jump or use stairs, and difficulty rising. PennHIP evaluation from 16 weeks provides the earliest validated assessment of hip joint laxity risk. OFA evaluation at 24 months provides the standard adult diagnosis.
Subtle signs can appear as early as 4β6 months in affected large breed puppies β post-rest stiffness, reluctance to jump, and rear-end gait changes. More obvious signs typically emerge between 8 and 18 months as the puppy adds weight and the developing hip joint undergoes increasing load. Secondary osteoarthritis, which adds an inflammatory component, typically develops from 2β5 years in dogs with established hip dysplasia.
An ideal starting point is around 8 months, when gut maturity is established and the growth window is at its most active phase. For large breed dogs at elevated hip dysplasia risk β Labrador Retrievers, Golden Retrievers, German Shepherds, Rottweilers, and other high-prevalence breeds β starting MoveGuard Growth at 8 months provides growth-window nutritional support for developing joint tissue during the period when management has the most impact on long-term outcomes.
The genetic predisposition cannot be eliminated β it is inherited. However, environmental factors during the growth window significantly influence how a genetic predisposition expresses clinically. Controlled growth rate (correct large breed puppy food), lean body condition, exercise management during the growth window, and early joint supplementation all have evidence supporting their role in reducing the severity of clinical hip dysplasia in genetically predisposed dogs.
