Use your own judgment. In other words, resist leaving food out for your pet all day long. This can contribute to overeating. Provide your pet with more exercise. Take him out for an extra little walk, or play with her in the house for half an hour.
Every little bit helps.

Older and overweight pets may be switched to special diets. You may want to consult with your vet to get recommendations. Click here for details.
