U.S. pet obesity rates continued to increase in 2012 with the number of overweight cats reaching an all-time high. The sixth annual National Pet Obesity Awareness Day Survey conducted by the Association for Pet Obesity Prevention (APOP) found 52.5 percent of dogs and 58.3 percent of cats to be overweight or obese by their veterinarian. That equals approximately 80 million U.S. dogs and cats at increased risk for weight-related disorders such as diabetes, osteoarthritis, hypertension and many cancers.
52.5% of US Dogs Overweight or Obese or approximately 36.7 million
58.3% of US Cats Overweight or Obese or approximately 43.2 million
“This is a war veterinarians, pet owners and parents must win. Obesity is the number one preventable medical condition seen in veterinary hospitals today and is the fastest growing health threat of our nation’s children. Our goal is to help pets and people live longer, healthier, and pain-free lives by maintaining a healthy weight, proper nutrition, and physical activity. The most important decision a pet owner makes each day is what they choose to feed their pet. Choose wisely. Your pet’s life depends on it.”
Dr. Ernie Ward, founder of Association for Pet Obesity Prevention

Research has shown that, in general, a healthy dog can abstain from food for five days before any noticeable health effects occur. They generally don't HAVE to eat every day. (Very small breeds are an exception...but unless there's really some medical problem present, missing a day of eating isn't a major catastrophe.) Always be sure fresh water is available. So start out by feeding a very high quality, complete and balanced dog food. Look on the ingredients list...MEAT should be the first item listed, not corn. You may also want to supplement with a vitamin/mineral/fatty acid product.
