Final answer:
Obese dogs and cats should be given food formulated with less fat and more fiber to help them manage their weight effectively, along with regular physical exercise.
Step-by-step explanation:
Obese dogs and cats should be fed food lower in fat and higher in fiber. Lowering the fat content helps to reduce the number of calories they consume, which can aid in weight loss or maintenance. Increasing dietary fiber is beneficial because it helps to promote satiety, meaning that pets will feel full for longer after eating, which can help prevent overeating. In addition to diet changes, regular exercise is also important for weight management in pets.
