What does a vet check during a joint examination?

When your dog starts showing signs of stiffness or limping, a veterinary joint examination becomes essential for understanding what's happening beneath the surface. These comprehensive assessments help identify the source of discomfort and guide treatment decisions that can significantly improve your dog's quality of life.

A thorough orthopaedic examination involves much more than a quick feel of your dog's legs. Veterinarians use a systematic three-part approach that combines careful observation, movement analysis, and hands-on assessment to build a complete picture of your dog's joint health.

Understanding what happens during these examinations can help you prepare your dog and recognise the early warning signs that warrant professional attention.

The Three-Part Examination Process

Veterinary joint examinations follow a structured approach designed to gather maximum information whilst keeping your dog comfortable. Each phase reveals different aspects of potential joint problems.

Observational Assessment

The examination begins before your vet even touches your dog. They'll watch how your pet moves naturally, looking for subtle signs that might indicate joint discomfort.

Key observations include how your dog rises from lying down, whether they favour particular limbs when standing, and if they show any trembling or asymmetry. These initial observations often pinpoint problem areas before any physical manipulation begins.

Your vet will also notice if your dog holds a limb up, shows uneven weight distribution, or displays malalignment when standing. These visual cues provide valuable clues about which joints need closer attention.

Gait Analysis

Movement assessment reveals information that static observation cannot provide. Your vet will watch your dog walk, trot, and possibly run at different speeds and from multiple angles.

For forelimb problems, veterinarians look for the characteristic head bob, where your dog's head rises when the painful limb bears weight and drops when the sound limb takes over. This creates a distinctive nodding motion that clearly identifies which front leg is causing trouble.

Hindlimb lameness shows differently, with hip hiking when the painful leg hits the ground and hip dropping when the sound leg bears weight. In severe cases, dogs may shift so much weight forward that they appear to have front leg problems too.

Physical Examination

The hands-on portion involves systematic palpation and manipulation of each joint. Your vet will typically start with your dog standing, then move to lying positions for more detailed assessment.

This phase evaluates joint alignment, muscle mass, swelling, and range of motion. By examining both sides simultaneously, veterinarians can quickly identify asymmetries that might indicate problems.

What Happens During the Standing Examination

With your dog standing naturally, your vet assesses overall posture and limb positioning. They'll look for muscle wasting, joint swelling, and how your dog distributes weight across all four legs.

Spinal examination receives particular attention, especially for dogs with hindlimb problems. Pressure applied along the vertebrae can reveal spinal pain that might be causing or contributing to leg lameness.

Your vet will palpate muscles for size and symmetry, feeling for areas of tension or atrophy that suggest compensation patterns or disuse.

Detailed Joint-by-Joint Assessment

Each joint receives individual attention, with specific tests designed to evaluate its particular anatomy and common problems.

Front Leg Examination

Starting with the toes and working upward, your vet examines each digit, checking for wounds, foreign bodies, or nail problems. The carpus (wrist) gets tested for stability and range of motion, which should normally flex to about 30 degrees and extend to 200 degrees.

Elbow assessment includes checking the collateral ligaments through gentle rotation movements. Your vet will feel for joint effusion, which appears most obviously on the outside of the elbow behind the bony prominence.

Shoulder examination evaluates the biceps tendon through direct pressure in the groove between the upper arm bones. The surrounding muscles also receive attention, particularly the supraspinatus and infraspinatus muscles that stabilise the shoulder joint.

Back Leg Examination

The hock (ankle) assessment includes stability testing and checking for fluid accumulation in the four joint pouches. Normal range of motion extends from 40 degrees of flexion to 165 degrees of extension.

Stifle (knee) examination involves several specific tests. Your vet will check how the kneecap tracks during movement and test the crucial cruciate ligaments using techniques like the cranial drawer test or tibial compression test.

Hip evaluation requires three-dimensional assessment, including flexion and extension, rotation, and side-to-side movement. Your vet will use anatomical landmarks to check for pelvic symmetry and assess the joint's stability.

Specific Diagnostic Tests

Beyond basic range of motion testing, veterinarians employ specific manoeuvres designed to identify particular conditions.

The tibial thrust test helps detect cranial cruciate ligament problems and can often be performed while your dog is awake. This test involves manipulating the lower leg bone to see if it slides forward abnormally when the knee is flexed.

Sitting assessment provides valuable information about stifle problems. Dogs with knee discomfort often avoid the normal sitting position, instead extending their legs to the side in what's called "puppy sitting."

The Ortolani test, used primarily in young dogs, checks for hip laxity that might indicate developmental problems. This involves gentle manipulation to assess how well the hip joint fits together.

Signs Your Dog Needs Joint Examination

Recognising when your dog needs professional joint assessment can make a significant difference in treatment outcomes. Some signs are obvious, whilst others require careful observation.

Clear Indicators

Obvious limping, reluctance to bear weight on a limb, or difficulty rising from rest clearly warrant veterinary attention. These signs typically indicate active discomfort that needs professional evaluation.

Visible swelling around joints, changes in how your dog sits or lies down, and reluctance to jump or climb stairs also signal potential joint problems requiring examination. If you notice any of these signs, speak to your vet about arranging an assessment.

Subtle Warning Signs

More subtle indicators include decreased enthusiasm for walks, changes in gait patterns, or altered exercise tolerance. Your dog might still move normally but show less interest in activities they previously enjoyed.

Behavioural changes like difficulty getting comfortable when resting, reluctance to be touched in certain areas, or mood changes related to movement can also indicate developing joint issues.

Muscle wasting in any limb suggests chronic compensation patterns that need addressing before they become more serious problems.

Advanced Diagnostic Options

When basic examination findings require further investigation, several advanced options are available.

Radiography remains the most common next step, providing detailed images of bone structure and joint alignment. Your vet might recommend comparison views of the normal limb to better identify abnormalities.

Ultrasonography helps evaluate soft tissues like tendons and muscles that don't show up well on X-rays. This technique is particularly useful for shoulder and elbow problems involving tendons or ligaments.

More advanced imaging like CT scans or MRI might be recommended for complex cases, whilst nuclear scintigraphy can help locate problems when the source of lameness isn't obvious from clinical examination. In some cases, your vet might recommend referral to an orthopaedic specialist for these advanced diagnostic procedures.

The Role of Early Detection

Early veterinary intervention significantly improves outcomes for dogs with joint problems. Catching issues in their initial stages allows for more conservative treatment approaches and prevents progression to more serious conditions.

Early detection also maintains your dog's quality of life by addressing discomfort before it becomes severe. This proactive approach often prevents secondary problems in other limbs that can develop when dogs compensate for discomfort in one area.

Regular monitoring becomes particularly important for older dogs or breeds predisposed to joint problems. Establishing baseline joint health through routine examinations helps identify changes more quickly.

Supporting Your Dog's Joint Health

Whilst veterinary examination and treatment remain essential for joint problems, owners can take several steps to support their dog's joint health between visits.

Maintaining appropriate body weight reduces stress on joints, whilst regular, appropriate exercise helps maintain joint mobility and muscle strength. Providing comfortable sleeping areas with adequate support can also help reduce morning stiffness.

Joint supplements may provide complementary support alongside veterinary care. MedPaw's hip and joint supplement contains glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata, offering comprehensive nutritional support for joint health when used as part of a complete care programme.

However, supplements should never replace professional diagnosis and treatment. They work best as part of an integrated approach that includes veterinary monitoring and appropriate management strategies.

Preparing for Your Dog's Joint Examination

You can help ensure a thorough examination by preparing your dog and gathering relevant information beforehand.

Note when you first noticed problems, what activities seem to worsen symptoms, and whether stiffness is worse at particular times of day. This information helps your vet understand the pattern and severity of your dog's condition.

Bring your dog on a lead to allow controlled movement assessment, and try to keep them calm to enable thorough examination. Most dogs tolerate joint examinations well, though anxious pets might benefit from gentle restraint or, in rare cases, mild sedation.

If you have concerns about what questions to ask your vet during the examination, preparing a list beforehand can help ensure you get all the information you need about your dog's condition and treatment options.

Understanding what happens during veterinary joint examinations helps you work effectively with your vet to maintain your dog's mobility and comfort. These comprehensive assessments provide the foundation for effective treatment plans that can significantly improve your dog's quality of life when joint problems develop. If you notice any signs of joint discomfort in your dog, speak to your vet about arranging an examination.
