When does a dog need to lose weight?

When a dog’s weight exceeds the healthy range it is time to lose weight. Excess weight raises the risk of high lipids, high blood sugar, osteoarthritis and heart/lung disease. To diet: control portions with low-calorie food on a schedule.

Second, walk and run daily to boost metabolism. Finally, avoid excess snacks and human food; use low-calorie ones like carrot, cabbage and apple.
