Worried that your small-breed dog is packing on the pounds? Run your hands along his backbone. You should be able to feel (but not see) his ribs. You also should see a clearly defined waist behind the ribs. If you can’t, follow these seven tips from Debra Eldredge, a veterinarian and co-author of “Dog Owner's Home Veterinary Handbook,” published by Howell Book House.
Before you put your overweight dog on a diet, schedule an appointment with the vet to make sure an underlying health problem isn’t causing the numbers on the scale to creep up.
Snacks and table scraps might account for your overweight dog’s bulging belly, Eldredge says. If curtailing in-between meals doesn’t make a difference, consider continuing with the same amount of food but switching to a different formula. Your vet can give you guidance.
Thawed frozen green beans, canned pumpkin (which is fiber-rich and filling) and cut-up carrots make satisfying, low-calorie snacks for your pet.
A study showed that dogs can count up to six or seven, Eldredge says. If he is accustomed to getting two small biscuits as a treat, break one biscuit into two pieces. By his count, he’s still getting two treats!
As much as your overweight dog loves treats, he also loves taking walks, playing and spending time with you. You also can replace biscuits with a couple of pieces of the kibble he would get during mealtime.
Is your bichon staring up at you with those beautiful eyes as you nibble on peanuts? He’s probably not hungry. As you have your snack, offer him a piece of kibble. If he turns it down, he’s not really hungry — he just wants your peanuts!
If your overweight dog has just a couple of pounds to lose, it can be hard to gauge whether he is making progress. Ask your clinic if it’s OK if you stop in once a week so he can step onto the doctor’s scale.
 
 If you see signs of aging in your dog, don't wait to feed him the proper diet. Feeding a high-quality, premium food throughout your dog's life is the best way to help him age gracefully. When your dog reaches his mature years, choose a food like IAMS™ ProActive Health™ Mature Adult for nutrition suited to this stage of life. 'Good nutrition starts early,' says Dr. Michael Hayek, an IAMS research nutritionist who specializes in geriatric nutrition. 'It should be viewed as proactive health care because it may be a deterrent to aging later on.'
 
If your dog already exhibits signs of aging, look for a high-quality, balanced maintenance food that caters to his changing metabolism. When you're shopping for a formula that's right for your dog, look for and compare these important points:
