Dogs do not tell us they are in pain. This is not stoicism in the heroic sense. It is a survival behavior inherited from ancestors where showing weakness attracted predators. The German Shepherd, working dog by heritage, often masks discomfort better than most breeds. I have examined German Shepherds with genuinely terrible radiographs, bone-on-bone arthritis, who trotted into my examination room with barely a perceptible change in gait. Their owners were shocked by the X-ray findings.
This capacity to hide pain means that behavioral and physical signs, observed carefully over time, often provide earlier warning of developing problems than waiting for obvious lameness. Learning to read these signs is one of the most valuable skills an owner of a shepherd breed can develop.
The Spectrum of Pain Expression
Hip pain in dogs exists on a spectrum, and so does its expression. Acute, severe pain, such as a traumatic injury, may produce vocalization, immediate non-weight-bearing, and obvious distress. Chronic hip dysplasia pain rarely presents this way. Instead, it builds gradually and the dog adapts gradually, making individual signs subtle and easy to dismiss as normal aging or temporary tiredness.
The key to recognizing chronic hip pain is pattern recognition, not individual symptoms. One morning of stiffness might be nothing. Stiffness every morning for three weeks is a pattern that warrants attention. The signs below should be evaluated in terms of frequency, duration, and whether they represent a change from the dog's previous behavior.
Gait Changes
The way a dog moves is the most direct expression of hip function. A trained eye can extract significant information from watching a dog walk, trot, and turn. You do not need a trained eye to notice obvious lameness, but subtler changes are worth knowing.
Bunny hopping: The signature gait abnormality associated with bilateral hip problems. Instead of alternating the rear legs during movement, the dog uses both together, taking off and landing simultaneously. This reduces the hip extension required from each joint individually. It is most visible when running on a surface where the dog can be observed from behind.
Short-striding rear gait: Reduced extension of the rear legs during each stride. The dog appears to push off without fully extending, keeping the hip in the less painful mid-range of motion rather than achieving full extension where dysplastic joints often hurt most.
Hip sway: Exaggerated lateral movement of the hindquarters when walking, sometimes called a rolling gait. This represents compensation for reduced front-to-back hip mobility.
Asymmetric footfall: When only one hip is primarily affected, the dog will shift weight toward the sound limb. Watch from behind for unequal loading, the sound-side limb seeming to carry more weight.

Postural and Resting Changes
How a dog holds themselves at rest reveals a great deal about hip comfort. Compare your dog's current resting habits to how they behaved a year ago.
Sitting with legs extended: A dog comfortable in their hips typically sits with their hind legs tucked neatly under or to the side. A dog with hip discomfort often extends one or both rear legs forward or to the side, avoiding the hip flexion that a normal sit requires.
Lying position changes: Dysplastic dogs often prefer to lie on their side rather than in the sphinx position, as lateral recumbency places less stretch on the hip structures. They may also change lying positions more frequently than before, unable to get comfortable.
Difficulty rising: The transition from lying to standing requires significant hip extensor strength and range of motion. A dog with painful hips may take multiple attempts to rise, push up with front legs first and drag the rear up behind, or hesitate before rising as if anticipating the discomfort.
Reluctance to sit on command: A dog who previously sat readily on cue but now hesitates, sits incompletely, or looks uncomfortable sitting may be experiencing hip pain. This is particularly telling because it represents a change from established behavior.
Activity and Behavioral Changes
Pain changes behavior. Dogs in chronic discomfort gradually restructure their activity patterns to minimize pain. These changes happen slowly enough that they can be mistaken for normal maturation.
Reduced enthusiasm for exercise: A dog who was previously excited for walks who now seems indifferent or who slows noticeably partway through activities they previously sustained without difficulty.
Reluctance to climb: Avoiding stairs, hesitating before jumping into a vehicle, refusing to get on furniture the dog previously mounted freely.
Shortened activity sessions: Lying down mid-play, seeking shade or rest during activities where the dog previously maintained energy throughout.
Irritability: Pain lowers the threshold for negative behavioral responses. A dog that has become more irritable, snaps when touched in the hip area, or reacts negatively to approaches that previously produced no reaction may be experiencing underlying pain.
Sleep changes: Difficulty settling, more frequent positional changes through the night, waking earlier than usual, or seeking softer sleeping surfaces all suggest discomfort.
Physical Signs You Can Observe
Regular hands-on interaction with your dog provides important physical information beyond what casual observation reveals.
Muscle asymmetry: Place your hands on your dog's hindquarters regularly and compare the muscle mass on each side. Significant muscle atrophy over one hip and thigh compared to the other indicates chronic disuse of that limb. Once you notice this, you are likely past the earliest stages of the problem.
Temperature differences: An actively inflamed joint is often warmer than the surrounding tissues. Comparing the temperature over each hip joint by gentle palpation may reveal asymmetry.
Reaction to hip palpation: Gentle pressure applied over the hip joint and surrounding musculature should produce no particular reaction in a comfortable dog. Flinching, turning to look at you, tensing muscles, or attempting to move away from the pressure suggests local pain.

When to Act on What You Notice
Not every sign warrants emergency veterinary intervention, but persistent or progressive signs warrant timely evaluation. Guidelines for timing:
- Seek prompt evaluation if your dog becomes suddenly non-weight-bearing on a rear limb without obvious trauma, shows acute distress with movement, or demonstrates pain that is clearly worsening.
- Schedule routine evaluation if you notice consistent gait changes, morning stiffness occurring more than occasionally, or behavioral changes suggesting reduced comfort or mobility.
- Discuss at next wellness visit if signs are subtle and inconsistent but represent a change from previous behavior patterns.
When you describe your observations to your veterinarian, be specific. Note when signs occur, in what context, how frequently, and how they compare to the dog's previous behavior. Specific observations lead to more targeted examination than general statements like "he seems a bit stiff sometimes."
Connecting Observation to Diagnosis
The signs described above can indicate hip dysplasia, but they are not exclusive to it. Other conditions including lumbosacral disease, bilateral cruciate injury, degenerative myelopathy, and other causes of rear limb dysfunction can produce similar presentations. Your observations drive the veterinary examination, which in turn determines the appropriate imaging and diagnostic workup.
Early detection is enabled by exactly the kind of attentive observation this article encourages. The owners whose dogs benefit from early intervention are those who noticed something, acted on it, and found a problem while options still existed. You are already in that group by knowing what to look for.
If hip dysplasia is confirmed, the comprehensive understanding of the condition and the range of management options available give you the foundation to work effectively with your veterinary team from that point forward.
