Just like in humans, carrying extra weight can have serious health consequences for dogs. When a dog weighs over 20% of their ideal body weight, they are considered obese. Being overweight puts additional strain on their organs and can lead to various health issues. As a responsible dog owner, it's important to be aware of the risks associated with overweight pets. Some of the health problems overweight dogs may face include diabetes, joint and bone damage, heart disease, high blood pressure, breathing difficulties, liver problems, and a reduced lifespan.
