Yep, eating when you are bored. Your pet does the same thing. Dogs prefer beef, pork, lamb and chicken to cereal foods. They actually prefer canned meat to fresh meat, ground meat to cubed meat, and cooked meat to raw meat. Canned or semi moist foods are preferred over dry food.
Dogs have special preferences for combinations of sugar and meat.
Although dogs are smart enough not to eat saccharin. The most important aspect to their food is not taste, but rather texture and odor of the food. In most cases the smell of coffee being grounded or perked, is better than its taste. Your Veterinarian will perform a medical exam so that he can rule out disease as the cause to your dog's weight gain. If you take your dog to a Holistic Veterinarian instead of a Traditional Veterinarian, the diet program will be different.
