A: My personal preference is not to use food at all. When I have trained dogs for obedience, I have always used the verbal praise-reward method. It works well, especially with some dogs who are not motivated by food rewards.
Many people do use treat-based training with success, but I don't recommend offering table scraps as the treat. Giving a dog people food—in training or just as a general reward—may give the dog the idea that such food is fair game. It might encourage your pet to steal food from the table or from people, especially kids or guests.
In addition, many human foods can be toxic to dogs. These include chocolate, grapes, raisins, macadamia nuts, and xylitol (a sweetener often used in gum, candy, and baked goods).
As an alternative to table scraps, you could train your dog with snacks that are tasty, low in fat, and commercially prepared for training. But keep in mind that soft chew snacks may be high in sugar, which is bad for dental health. When shopping for treats, read package labels and choose premium varieties that list meat as the first ingredient.
Use only small amounts for training purposes—treats should not interfere with the consistency of a normal diet or greatly affect the caloric intake for the size and age of the dog. The training sessions should be short in length and repeated several times throughout the day. For young dogs, the training period should be no longer than five minutes.
Finally, the most important training tip is to keep it positive. If you're getting frustrated with your puppy's naturally short attention span, take a break. Strive to end the session on a positive note so your pet will be eager for the next time.

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.
