Tendinopathy
This page is for educational purposes only and is not a substitute for veterinary diagnosis or emergency care. Always consult your primary veterinarian or a rehabilitation veterinarian before starting treatment. If your pet cannot walk, has sudden paralysis, severe pain, or breathing difficulty, seek urgent veterinary attention.
What is Tendinopathy?
Also known as: tendinitis (inflammatory phase terminology); tendinosis (degenerative tendon change); overuse tendon injury.
Tendons transmit muscle force to bone. When load repeatedly exceeds the tendon’s capacity to adapt, collagen organisation and pain signalling change — producing tendinopathy. In dogs, common sites include the biceps, supraspinatus, Achilles (common calcaneal) tendon, and others depending on sport and conformation. Cats may develop tendon issues after trauma or chronic overload, though they present less often.
Unlike a one-off muscle strain, tendinopathy often has a more insidious onset and may worsen with continued high-load activity. Diagnosis combines orthopaedic exam with ultrasound or MRI when needed. Complete ruptures are a different entity requiring different management.
Modern rehab emphasises progressive tendon loading, not only rest and anti-inflammatories. Absolute rest can reduce load capacity further; carefully dosed exercise remodels tendon under guidance.
Common signs to watch for
Signs vary by severity and by whether your pet is a dog or cat. Owners of dogs and cats often notice:
- Activity-related lameness that eases or worsens in a recognisable pattern
- Local tendon-region pain or thickening on veterinary exam
- Stiffness at the start of exercise in some cases
- Reduced performance: slower weave times, reluctance to jump, shortened stride
- Occasional swelling near tendon sheaths when tenosynovitis coexists
- Chronic intermittent lameness if overload continues
Causes & contributing factors
- Repetitive overload from sport, work, or play beyond current capacity
- Sudden training spikes after a layoff
- Biomechanical factors: conformation, paw placement, concurrent joint disease
- Age-related tendon changes reducing resilience
- Previous partial injury with incomplete rehabilitation
How veterinary rehabilitation helps
Assessment identifies which tendon is irritable and which loads provoke it. Early phases may reduce provocative activity while introducing isometric and heavy-slow resistance work as tolerated.
Manual therapy addresses surrounding muscle guarding. Modalities may support comfort as an adjunct. Hydrotherapy and land-based progressive programmes rebuild tensile strength.
Return-to-sport testing looks at symmetry, endurance, and task-specific drills before full competition loads resume.
Rehabilitation plans at RehabVet are individualised after a veterinary assessment. We coordinate with your primary vet when imaging, medication, or surgery is part of the overall plan.
Modalities & services commonly used at RehabVet
Depending on your pet’s examination findings, comfort, and goals, a plan may include one or more of the following:
Expected rehabilitation goals
Goals are set for the individual patient. Typical aims may include (not guarantees — outcomes vary):
- Reduce tendon irritability and functional lameness
- Increase tendon load tolerance through progressive exercise
- Correct kinetic-chain contributors (core, hips, shoulders)
- Prevent progression to partial or complete rupture where possible
- Guide a structured return to activity or sport
We do not publish invented success percentages. Progress is tracked clinically (gait, strength, range of motion, pain behaviours, and home function) and plans are adjusted over time.
When to seek veterinary care
- Lameness lasting more than a few days or recurring with the same sport
- Sudden drop in the hock (plantigrade stance) suggesting Achilles involvement — urgent vet care
- Hot, swollen tendon regions or non-weight-bearing lameness
- Before increasing training intensity after a layoff
- Will anti-inflammatory medication alone fix tendinopathy?
Medication may ease pain short-term but does not restore tendon load capacity. Progressive, guided loading and activity modification are central to durable improvement.
- Is massage enough?
Soft-tissue work can help comfort but is rarely sufficient alone. Tendons remodel with appropriate mechanical loading prescribed by a rehab professional.
- How long does tendon rehab take?
Tendon adaptation is slow compared with muscle. Timelines are individual and depend on severity, chronicity, and sport demands — we track function rather than promise a fixed number of weeks.
