In this CAM LIVE episode, Esme Howells is joined by Helen Coleman and Victoria Bowes to explore practical, everyday approaches to managing obesity in dogs.

The conversation focuses on realistic strategies caregivers can implement at home, from portion control and feeding habits to enrichment-based approaches that support both physical and mental wellbeing. A key concept discussed is the Delboeuf illusion, demonstrating how bowl size and presentation can influence how much we perceive as an appropriate portion, often leading to unintentional overfeeding.

Helen and Victoria share a range of practical feeding tips and enrichment ideas that can help reduce calorie intake while maintaining satisfaction and engagement for the dog. The episode highlights how small environmental and behavioural adjustments can make a meaningful difference in long-term weight management.

This episode aligns closely with CAM’s focus on weight management, emphasising that sustainable change comes from consistent daily habits rather than short-term interventions.

Key take homes

1. Obesity management often starts with human perception, and tools like the Delboeuf illusion highlight how easily portion sizes can be misjudged.

2. Small environmental changes, such as bowl size and feeding presentation, can significantly influence feeding behaviour and calorie intake.

3. Enrichment feeding is a powerful tool, helping to slow intake, increase mental stimulation and improve satiety without increasing calories.

4. Sustainable weight management depends on consistent daily habits rather than restrictive short-term diets.

5. Educating caregivers on practical, realistic strategies is key to achieving and maintaining a healthy body condition in dogs.

In this CAM LIVE episode, Hannah Capon speaks with veterinary physiotherapy researcher Heli Hyytiäinen about the growing recognition of obesity in dogs as a major welfare issue. Alongside dental disease and osteoarthritis, excess weight is now understood to be one of the most significant health challenges affecting companion animals.

The discussion explores why obesity is far more than a cosmetic concern or a simple co-morbidity risk for conditions such as heart disease or diabetes. Excess adipose tissue acts as a metabolically active organ, producing pro-inflammatory mediators that contribute directly to the development and progression of osteoarthritis.

Heli highlights emerging research showing that obese dogs may accumulate lipid droplets within muscles, tendons and ligaments, affecting tissue performance and recovery capacity. These physiological changes can alter biomechanics, reduce efficiency of movement and exacerbate joint disease. Studies comparing lean and obese dogs demonstrate that stride length is often shorter in overweight animals, while joint range of motion can appear increased due to compensatory movement patterns.

Whether a dog currently has arthritis or not, maintaining a lean body condition is one of the most powerful preventative strategies for long-term musculoskeletal health.

She earned a Master of Science in Veterinary Physiotherapy from the Royal Veterinary College in 2012 and completed her PhD at the University of Helsinki in 2015. She founded and developed the physiotherapy department at the Veterinary Teaching Hospital of the University of Helsinki, where she continues to combine clinical work with research. She lectures internationally on animal physiotherapy, teaches within Finnish animal physiotherapy specialization programmes and is an honorary lecturer for the MSc Veterinary Physiotherapy programme at the University of Liverpool.

Key take homes

1. Obesity in dogs is now recognised as a major welfare concern alongside dental disease and osteoarthritis.

2. Adipose tissue is metabolically active and releases inflammatory mediators that contribute directly to the progression of arthritis.

3. Obesity affects musculoskeletal tissues beyond joints, with lipid deposits identified in muscles, tendons and ligaments that impair function and recovery.

4. Biomechanical differences exist between lean and obese dogs, including shorter stride lengths and altered joint movement patterns.

5. Even modest weight loss of around 6–9 percent body weight can lead to measurable improvements in lameness and mobility in dogs with osteoarthritis.

In this CAM LIVE, Hannah Capon speaks with leading veterinary obesity researcher Alex German about one of the most significant health challenges affecting companion animals today: excess body weight. With more than 50 percent of pet dogs now classified as overweight or obese, the discussion highlights why this issue has become a welfare concern of epidemic proportions.

Alex provides an overview of the scale of the obesity problem in dogs, the key factors contributing to weight gain, and the strong association between obesity and musculoskeletal disease, particularly osteoarthritis. The conversation explores how excess weight increases mechanical strain on joints while also driving systemic inflammation that worsens pain and mobility problems.

The discussion then moves to practical strategies for safe and sustainable weight management. Alex explains why gradual, controlled weight loss is essential and how long term success depends on building consistent feeding routines, managing treats, and supporting caregivers in maintaining healthy habits for their dogs.

The episode also considers whether particular food groups can influence weight loss and long term weight control, and discusses preventative approaches that can help stop obesity developing in the first place.

Guest Bio

Alex German is Royal Canin Professor of Small Animal Medicine at the University of Liverpool. He is a Diplomate of the European College of Veterinary Internal Medicine, a recognised specialist in internal medicine with the Royal College of Veterinary Surgeons, and a Senior Fellow of the Higher Education Academy.

His main clinical and research interest is the prevention and management of obesity in companion animals. For more than fifteen years he has run the Royal Canin Weight Management Clinic at the University of Liverpool, a specialist clinic dedicated to improving the quality of life of overweight pets through clinical excellence, research and education.

Key takehomes

1. More than half of pet dogs are now overweight or obese, making excess weight one of the most common and serious health concerns in companion animals.

2. Obesity is strongly linked with musculoskeletal disease, including osteoarthritis, increasing both joint loading and systemic inflammation that contributes to chronic pain.

3. Safe weight loss must be gradual and carefully managed to protect health and improve the chances of maintaining weight loss long term.

4. Successful weight management relies on behaviour change for both dogs and caregivers, including portion control, consistent feeding routines and careful management of treats.

5. Prevention is critical. Monitoring growth in young dogs and recognising weight gain early can significantly reduce the likelihood of obesity developing later in life.
