Obesity is the most common form of malnutrition in pets and increases their risk of developing a whole range of health problems, including heart disease, arthritis, diabetes and cancer.
Look out for the following signs of obesity: an inability to feel a pet's ribs; an inability to see a pet's waist; tiredness, lethargy or shortness of breath.
If your pet really is your best friend and you want it to live a long and happy life, feed it the right amount of healthy food and take it for regular walks, which will help to beat the bulge. Your local vet can also give your pet a free weight check as well as advise you on how to put your pet on a weight management programme.
