Canine Obesity
Excess weight is widely regarded as the most common preventable condition in dogs — and one of the most addressable at home with a measured plan agreed with your vet.

Why it matters
Long-running studies, including the well-known Purina Lifespan Study in Labrador Retrievers, suggest that lean body condition is associated with longer life and later onset of age-related disease. Excess adipose has been linked to osteoarthritis, diabetes, urinary disease, anaesthetic risk, and reduced quality of life.

Common elements of a weight-loss diet
- Calorie target: commonly set as a percentage of resting energy requirement at the dog's target body weight. Your vet will set the right number.
- Higher protein: helps preserve lean mass during weight loss.
- Moderate-to-lower fat: reduces calorie density.
- Added fibre: can support satiety so dogs don't beg through the deficit.
- Treats counted: a common guideline is to keep treats to no more than around 10% of daily calories.
