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.

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.
