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.
Janet Tobiassen, DVM, a veterinarian based in the state of Washington, has been practicing and writing about vet medicine since 1999. She started training dogs at age 12, through 4-H, and continued pet therapy and obedience training in veterinary school and beyond.

Diet plays an important role in the endurance potential of canine athletes. The Alaskan sled dog might be considered the ultimate canine athlete, sometimes pulling a sled more than 1,000 miles in subzero temperatures. Providing a well-balanced diet is essential to meet the special needs of dogs in such nutritional-stress situations. Not only should the diet fed to these dogs be high in protein, but it also should be high in fat, which serves as the major energy source for exercising muscles.
A high-fat diet can help muscles burn fat more efficiently. During sustained exercise, fatty-acid oxidation is the primary source of energy for the muscles. Increasing the efficiency of fat metabolism spares the body’s use of carbohydrates, and because most dogs have in excess of 10 to 50 times more energy stored in fat than in muscle glycogen (carbohydrate), this might boost the animal's exercise performance.
IAMS™ studies1 have shown that in trained sled dogs as in ordinary dogs, exercise performance was enhanced by switching from a low-fat to a high-fat diet (from 25 to 65% of calories from fat), as indicated by increased:
When dogs were switched back to a low-fat diet, all of these criteria decreased to their previous values.
These results indicated that by increasing the availability of fat stores and capacity to metabolize fat for energy, a high-fat diet promotes exercise endurance in canine athletes.
