“…Approximately 50% of dogs are overweight, and approximately 20% are obese. 3,[5][6][7] Although there is no objective measure for obesity that is readily available to the general population, dogs with body weight 15% to 20% or more above ideal weight 5 can be assessed as obese, and obesity can be determined by use of a body composition scale such as the 9-point BCS system developed by researchers at Purina, which relies on physical examination, palpation, and a visual aid chart. 8 Certain breeds such as Labrador Retrievers and Beagles seem predisposed to obesity, 9 although obesity can develop in any purebred or mixed-breed dog.…”
