In this episode of Canine Arthritis Matters, Hannah Capon speaks with Arielle Griffiths about one of the biggest yet most under-recognised drivers of chronic pain in dogs: excess weight.

The discussion explores why weight conversations are so emotionally and professionally difficult, why obesity remains under-acknowledged by caregivers, and how early identification of unhealthy weight trajectories could dramatically change the future of osteoarthritis in dogs.

Together they unpack the landmark Purina lifetime feeding study, behavioural and social barriers to weight management, and the ways nutritional choices influence inflammation, mobility and long-term pain. Arielle also shares her unconventional career journey into plant-based nutrition, the realities of trying to run a weight-loss clinic with no uptake, and what she now teaches caregivers about simple, achievable nutritional changes.

This episode sits squarely within CAM’s March theme: weight management. Recognising unhealthy weight early and supporting caregivers with realistic, sustainable strategies is one of the most powerful ways we can reduce osteoarthritis risk and improve long-term comfort.

Bio

Arielle Griffiths is a UK veterinarian, environmentalist and founder of a plant-based pet nutrition company. After 25 years in first-opinion practice, a confronting day at the PDSA led her to re-evaluate the scale of the obesity epidemic and its connection to chronic disease.

She retrained extensively in nutrition, developed a strong interest in plant-based formulations, and now works exclusively online supporting caregivers in managing weight, digestive disease and inflammatory conditions through practical, achievable nutritional changes.

Key takehomes

1. Weight is one of the strongest risk modifiers for osteoarthritis, yet it remains under-identified and under-discussed in clinical practice.

2. Caregivers often cannot recognise overweight animals; the perception gap between what owners believe and clinical reality is substantial.

3. Lifelong lean management dramatically delays OA onset, reduces severity and extends life expectancy; identification must happen early, ideally in puppyhood.

4. Behavioural, emotional and social factors make weight-related conversations difficult; empathy, permission and simple actionable steps are essential.

5. Even small nutritional changes and replacing inflammatory treats with whole-food alternatives can produce measurable improvements in comfort and mobility.

Stay tuned to learn how early detection can make a significant difference in managing OA in younger dogs.

Dr Masataka Enomoto joins CAM to explore the frontier of early identification in canine osteoarthritis. From automated pain evaluation and force-plate research to activity-monitor insights, microbiome patterns and his landmark data on how young dogs really are when radiographic OA appears, this episode dives deep into what the next decade of OA detection could look like.

Listeners will gain clarity on why early OA is still routinely missed, what technologies show genuine promise, and how objective tools could reshape the caregiver–vet partnership in spotting pain far earlier.

Bio

Dr Masataka Enomoto is a Research Assistant Professor of Orthopedic Surgery at North Carolina State University. He earned his veterinary degree from Azabu University in Japan and now focuses on cartilage regeneration, pain management, early OA detection and comparative orthopaedic research.

His publications cover NGF-blocking monoclonal antibodies, force-plate gait analysis, activity monitors, microbiome associations, and the prevalence of radiographic OA in young dogs.

Key takehomes

1. Automated pain evaluation is progressing but not yet ready for widespread clinical use; it holds strong promise for future early OA detection.

2. Activity monitors can reveal early reductions in movement long before lameness appears, but they remain underused in practice.

3. Microbiome research is emerging and may help explain multi-joint OA patterns; however, clinical application is still distant.

4. Comparative force-plate work has provided objective insight into the performance of grapiprant versus bedinvetmab in early OA pain management.

5. Dr Enomoto’s prevalence research confirms radiographic OA is common even in young dogs, underscoring how urgently early identification must become routine.

February at Canine Arthritis Matters focuses on identification — and in this episode we explore what early identification of osteoarthritis could look like in the future.

Hannah Capon is joined by Dr Eva Hanks, CEO and founder of MI:RNA, to discuss the emerging role of microRNA (miRNA) biomarkers in detecting canine osteoarthritis at a molecular level.

We know that most dogs are diagnosed with OA once structural damage is already present. Subtle behavioural, postural and gait changes are often missed or dismissed. So what if we could detect disease before radiographic change, before overt lameness, before chronic pain becomes entrenched?

Dr Hanks explains what miRNAs are, how they function biologically, and why they may act as measurable indicators of early pathological change. This conversation explores the human evidence base, the current state of canine research, the challenges of variability between breeds and individuals, and whether the veterinary profession is ready to adopt biomarker technology as part of routine identification strategies.

This is a forward-looking discussion about moving from subjective suspicion to objective identification — and what that could mean for the future of canine osteoarthritis management.

Guest Bio

Dr Eva Hanks is CEO and founder of MI:RNA, a veterinary diagnostics company focused on early disease identification through biomarker technology combined with artificial intelligence. MI:RNA is a spin-out from Scotland’s Rural College (SRUC).

Dr Hanks began her career in busy mixed practice before returning to academia to complete an advanced certificate, followed by a PhD in immunology. She later worked as a clinical pathologist before launching MI:RNA in 2019, bringing together research, clinical insight and diagnostic innovation to improve early disease detection in companion animals.

5 Key Takeaways

1. We currently identify osteoarthritis too late, often after structural joint damage and chronic pain patterns are established.

2. MicroRNAs are regulatory molecules that reflect active biological processes and may allow identification of osteoarthritis at a molecular stage before visible joint changes occur.

3. Human meta-analyses show strong diagnostic accuracy for miRNAs in OA, but robust canine validation is essential before widespread clinical adoption.

4. Objective biomarkers could complement clinical assessment, helping bridge the gap between caregiver-reported subtle changes and definitive diagnosis.

5. Early identification opens the door to earlier lifestyle modification, weight management, activity optimisation and targeted intervention — shifting OA management towards prevention of progression rather than reaction to damage.

Stay tuned to learn how early detection can make a significant difference in managing OA in younger dogs.

In this episode, Dr. Hannah Capon speaks with Dr. Rachel Dean about the complexities of identifying arthritis early, the need for better contextualised care, and the shared responsibilities between caregivers and professionals. They explore what evidence shows about how OA is actually recognised in practice, why early signs are routinely missed, and how communication, telemedicine and structured preparation can dramatically improve outcomes. Dr. Dean also discusses neutering evidence, the role of telemedicine for chronic disease, and why evidence-based veterinary medicine (EBVM) underpins every decision we make. This conversation reinforces a core truth: early recognition of arthritis is achievable, but only if we broaden our observational habits, strengthen collaboration, and align interventions with real-world context.

GUEST BIO

Dr. Rachel Dean qualified in 1996 and has held influential roles across clinical practice, research, shelter medicine and academia. She is the founding director of the Centre for Evidence-based Veterinary Medicine at the University of Nottingham, former Associate Professor of Feline Medicine, Founding President of the Association of Charity Vets, and Editor-in-Chief of the BSAVA Manual of Shelter Medicine. She holds a Masters in evidence-based medicine, a PhD in epidemiology, a Diploma in feline medicine, and is a Senior Fellow of the Higher Education Academy. She is now Director of Clinical Research and Excellence in Practice at VetPartners, leading their Clinical Board and Learning & Development teams.

KEY TAKEAWAYS

1. Early arthritis is most often detected through subtle behavioural and lifestyle changes rather than clear lameness, making caregiver observations essential.

2. The Dean–Belshaw–Asher study shows a significant mismatch between what caregivers report and what clinicians focus on during consults, which can delay diagnosis.

3. Effective contextualised care requires collaboration: caregivers documenting changes and clinicians asking more precise, targeted questions.

4. Telemedicine can support earlier recognition by capturing movement, behaviour and environmental clues that are missed in-clinic.

5. Prevention and early management hinge on lifestyle adjustments, structured monitoring and proactive intervention, not necessarily costly treatments.

In this episode, Dr. Hannah Capon speaks with veterinary behaviour specialist Dr. Katrin Jahn about why arthritis is so often missed, how subtle behaviour and lifestyle changes can signal discomfort long before lameness appears, and how structured observation helps bridge the gap between caregivers, trainers and veterinary professionals. Together they explore the early indicators of chronic pain, the value of simple tools that guide objective reporting, and how better communication leads to earlier intervention and improved long-term welfare. This episode reinforces that arthritis is not just a mobility issue, but a whole-dog condition that requires careful observation, teamwork and timely action.

GUEST BIO

Dr. Katrin Jahn is a veterinary behaviour specialist and founder of Trinity Veterinary Behaviour, with extensive experience supporting complex behaviour and medical cases across multiple countries. Her work focuses on the intersection between emotional wellbeing and physical health, helping caregivers and professionals recognise when pain is influencing behaviour. Katrin is committed to promoting accessible tools, collaborative case management and improved welfare through better early identification of chronic pain.

KEY TAKEAWAYS

• Arthritis rarely starts with an obvious limp; behavioural and lifestyle changes are often the first clues

• Pain influences emotion, capability, mobility, and appearance – observing patterns over time is essential

• Trainers and caregivers play a crucial role in spotting early signs, and structured reporting improves accuracy

• Communication gaps between caregivers, trainers and vets often delay diagnosis

• Simple tools, used consistently, can guide earlier identification and therefore earlier intervention

• Chronic pain management requires shared responsibility across all professionals involved

• Prevention starts with knowing what to look for – observation is the foundation of early arthritis detection

In this episode, Hannah speaks with orthopaedic surgeon and rehabilitation expert Dr David Dycus to examine the real challenges of early arthritis detection. Together, they explore why early identification is often missed, what responsibilities both caregivers and professionals share, and which interventions truly shift the trajectory of osteoarthritis.

Aligned with CAM’s January prevention theme, this conversation highlights how critical early lifestyle decisions are for long-term joint health. Many of the most effective interventions are neither invasive nor expensive: bodyweight control, activity optimisation, home adaptation, and proactive monitoring form the foundation. Hannah also taps into Dr Dycus’s extensive orthopaedic and rehabilitation experience, asking how he approaches cases where pain is the only visible sign and what he recommends for both early and moderate disease.

The LIVE concludes with CAM’s signature segment: Ten Top Tips for managing your arthritic dog (from 1:02:00 in the original video).

Guest Bio

Dr David Dycus obtained his veterinary degree at Mississippi State University’s College of Veterinary Medicine, completed a small-animal rotating internship at Auburn University, and returned to Mississippi State for a combined surgical residency and Master’s degree. He sits on the research committee of the American College of Veterinary Surgeons and has a strong clinical and research interest in arthritis, joint disease, regenerative medicine, and minimally invasive orthopaedic surgery.

Dr Dycus is trained in arthroscopy, minimally invasive fracture repair, and advanced procedures for cruciate ligament injury. He gained stem-cell certification in 2010 and became a certified canine rehabilitation practitioner through the University of Tennessee in 2015. He is co-founder and co-director of the Veterinary Sports Medicine and Rehabilitation Institute (VSMRI), an online rehabilitation education platform, and is the founder and CEO of Dycus Veterinary Consulting.

Key Takeaways

1. Early identification of arthritis is a shared responsibility between caregivers and veterinary professionals.

2. Many impactful interventions are lifestyle-based, low-cost, and can be implemented long before medication is needed.

3. Pain as the sole clinical sign is easy to miss; subtle changes matter and should prompt assessment.

4. Early and moderate OA require different strategies, but both benefit from proactive monitoring and joint-friendly routines.

5. No intervention works alone; multimodal management started early has the greatest protective effect on long-term mobility.

In this episode, Hannah welcomes back Dr Dan O’Neil to expand on the latest findings from VetCompass, the companion animal surveillance programme based at the Royal Veterinary College. Building on his previous CAM appearance, Dr O’Neil explains how large-scale clinical data is helping us understand which disorders affect our dogs most frequently, why they occur, and how this knowledge can improve welfare across all breeds.

As January at CAM focuses on prevention, this conversation highlights the essential role of early identification, awareness of developmental joint disease, and responsible decision-making throughout a dog’s early life. By understanding risk patterns across the wider population, caregivers and professionals can take meaningful steps to protect joint health long before clinical arthritis develops.

Originally published as a LIVE broadcast in January 2024

Guest Bio

Dr Dan O’Neil is Associate Professor in Companion Animal Epidemiology at the Royal Veterinary College and co-lead of the VetCompass Programme. After 22 years in both small and large animal practice, he completed an MSc in epidemiology in 2009 and a PhD in 2014 focused on developing VetCompass, now a global leader in companion animal health surveillance.

He has authored over 100 scientific papers on breed health and therapeutics, co-authored the books Breed Predispositions to Disease in Dogs and Cats and Health and Welfare of Brachycephalic Companion Animals, and chairs the UK Brachycephalic Working Group. His work has been recognised with multiple honours including Fellowship of the Royal College of Veterinary Surgeons, the BSAVA Blaine Award and the International Canine Health Award. His ethos is simple and powerful: we must understand the world better in order to make it better.

Key Takeaways

1. Developmental joint disease is a major driver of lifelong mobility problems, making prevention in young dogs essential.

2. Surveillance data challenges assumptions and provides evidence-based insight into true disease prevalence and risk.

3. Breed-related risk varies significantly and must be considered when making breeding, acquisition and lifestyle decisions.

4. Prevention is multi-layered and includes genetics, growth, body condition, environment and early monitoring.

5. Data-driven understanding empowers caregivers and professionals to intervene earlier and reduce long-term suffering.

In this episode of Canine Arthritis Matters, Hannah Capon is joined by Dr. Michelle Kutzler, a leading expert in veterinary reproduction, to tackle one of the most emotionally charged and confusing topics for caregivers and professionals alike: whether, when, and how to neuter dogs.

Drawing on decades of research and clinical experience, Michelle explains why there is no single correct answer to neutering decisions. The conversation explores the hormonal consequences of gonad removal, particularly the long-term elevation of luteinizing hormone (LH), and how this may influence musculoskeletal health, joint disease, ligament integrity, cancer risk, and behaviour.

Together, Hannah and Michelle discuss early neutering and skeletal development, osteoarthritis risk, ligament laxity, body composition changes, and the emerging evidence linking neutering to anxiety-related behaviours. They also explore alternative sterilisation options, including vasectomy, hysterectomy without ovary removal, intratesticular injections, and hormone-modulating implants such as deslorelin.

This episode emphasises contextual, individualised decision-making and highlights the importance of balancing health risks, benefits, and caregiver trade-offs. It is the first part of a wider conversation, with a follow-up episode planned.

Guest Bio

Dr. Michelle Kutzler graduated from Washington State University College of Veterinary Medicine in 1993 and completed a residency in theriogenology at Cornell University, followed by a PhD in physiology. She has held academic positions at Oregon State University and, as of July 2025, joined the University of Minnesota College of Veterinary Medicine faculty.

Dr. Kutzler has authored over 100 peer-reviewed publications, more than 30 book chapters, and two textbooks in the field of animal reproduction. She serves as Chair of the World Small Animal Veterinary Association Reproduction Control Committee, co-chairs the International Symposium for Canine and Feline Reproduction Scientific Committee, is a scientific advisor for the Alliance for Contraception in Cats and Dogs, and is President-Elect of the American Association of Small Ruminant Practitioners.

Her research focuses on the systemic effects of gonadectomy, endocrine balance, musculoskeletal health, cancer risk, and behaviour.

Key Takeaways

1. There is no universal answer to whether or when dogs should be neutered; decisions must be individualised.

2. Early neutering permanently alters skeletal development, joint angles, muscle mass, and ligament stability, increasing OA risk.

3. Removal of gonads leads to lifelong elevation of luteinizing hormone, which has receptors throughout the body, including joints, ligaments, and the brain.

4. Some anxiety and behaviour changes in neutered dogs may be hormonally driven and, in certain cases, improve with LH suppression.

5. Alternative sterilisation options exist and should be discussed openly alongside traditional spay and neuter surgery.
