Nutritional welfare in dogs encompasses both overnutrition leading to obesity and undernutrition, with both causing significant welfare impacts across the companion dog population.
Obese dogs live in a state of chronic musculoskeletal discomfort and reduced ability to exercise, which itself is a welfare need. Owners frequently underestimate their dogs' body condition, making veterinary guidance on weight management essential. Conversely, inappropriate home-prepared diets that are nutritionally incomplete cause deficiency diseases. Evidence-based nutritional management by veterinary professionals is the gold standard for canine nutritional welfare.
