Obesity in dogs, also known as overweight, is a significant health concern that affects many pets. It is characterized by an excess of body fat, which can lead to various health issues if not properly managed. The causes of obesity in dogs are multifactorial and include a sedentary lifestyle, excessive caloric intake, and a lack of regular exercise. It is essential for dog owners to monitor their pet's weight and consult with veterinarians to develop an appropriate diet and exercise plan tailored to the dog's breed, age, and overall health condition. Regular check-ups can help detect obesity early and prevent potential complications such as joint problems, diabetes, and cardiovascular diseases. By maintaining a healthy weight, dogs can enjoy improved mobility, increased lifespan, and an enhanced quality of life.
