The natural scavenging behaviour of dogs can often lead to them overeating which can lead to obesity. Much like in humans, overeating can have numerous health implications for dogs. It can potentially cause heart problems, diabetes, and joint pain.

Certain breeds of dogs such as Basset Hounds, Dachshunds, and Cavalier King Charles Spaniels have genetic factors that make them more susceptible to gaining excess weight.

Consequently, large-bodied breeds with thin legs such as Rottweilers and Staffordshire Bull Terriers can suffer from ligament problems due to the increased stress placed on their joints from the extra weight.
