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.

Nutrients like protein, fat, vitamins and minerals are vital to the skin and coat health of dogs. Your dog’s coat is made up almost entirely of protein. If his diet doesn’t contain enough protein quantity and quality, hair might fall out or become dry, weak and brittle. Likewise, his skin is made up of tightly packed flat cells with tough membranes made of proteins and fats. Without proper amounts of these nutrients, the cell membranes weaken, allowing water to escape and bacteria and viruses to enter more easily.
Make sure your dog is getting the following nutrients to keep his coat and skin healthy.
Proteins are found in both animal-based and plant-based ingredients. However, animal-based proteins contain all the essential amino acids dogs need, whereas plant-based proteins might not contain enough of some essential amino acids.
Fats also are found in both animal- and plant-based ingredients and are incorporated into skin cells as fatty acids. In particular, linoleic acid is essential for a dog’s skin and coat health. Without enough linoleic acid, dogs might experience a dull and dry coat, hair loss, greasy skin and increased susceptibility to skin inflammation.
Linoleic acid is found in chicken fat and vegetable oils (such as corn and soybean). IAMS™ research has also found that the fatty acids in vitamin-rich fish oils help promote excellent skin and coat health.
Your dog needs vitamins and minerals for a healthy skin and coat. The best way to provide these nutrients is by feeding a complete and balanced diet full of essential vitamins and minerals, rather than giving him supplements.
Vitamin or Mineral Importance to Skin and Coat Health
Vitamin A Necessary for growth and repair of skin
Vitamin E Protects skin cells from oxidant damage
Vitamin C Helps heal wounds
Biotin Aids in the utilization of protein
Riboflavin (B2) Necessary for fat and protein metabolism
Zinc Necessary for fat and protein metabolism
Copper Involved in tissue, pigment, and protein synthesis
Diet can be a factor when changes in skin and coat condition occur, but the most common causes are season and life stage. As cold weather approaches, most dogs grow a thick coat to help keep heat in and cold air out. As the weather warms up, they shed their thick, heavy coat.
Most puppies are born with soft, fuzzy hair, but as they age, a coarser coat grows. Pregnant or nursing dogs also might experience a change in coat condition or hair loss. And, as with humans, a dog’s hair might thin out and become coarser and white as he reaches his mature years.
