It seems that humans aren't the only ones in the U.S. that need to worry about the obesity epidemic, as new research reveals that half of American dogs are overweight, according to the New York Times.

The new study by Association for Pet Obesity Prevention, founded by a veterinarian to draw attention to the issue, emphasizes that like humans, overweight dogs face the risk of developing weight-related diseases such as diabetes, arthritis and high blood pressure as well as kidney and respiratory ailments.

Experts warn that pet owners may need to cut back on giving their dogs tasty table scraps, though the focus must be on exercise as well as diet.

Cesar Millan, famous dog trainer and television personality, promotes the philosophy of "exercise, discipline, affection" in raising our beloved furry companions, and pointed out that unlike their wild ancestors, dogs today essentially have "butlers and maids" who provide them food. Now more than ever, he said, dogs need to be physically and mentally challenged in order to stay healthy.

"A dog can give me big puppy-dog eyes, and I'm still not going to give him a piece of chicken," Dr. Angela Witzel, a veterinarian at the University of Tennessee who specializes in animal nutrition, told the New York Times.

Dr. Witzel runs a fat camp for dogs, and notes that her "inpatient" canines tend to have more success down the road, as they are guaranteed to be exercising daily.

"If you are going to use a homemade dog food, consult a veterinarian," Dr. Witzel advised. "For instance, a dog doesn't need carbohydrates unless she is pregnant or lactating."

Dr. Witzel also advocates for a raw diet, also known as "the prey diet," consisting of frozen or cooked chicken, rabbit or squirrel, though admitted this option may not be feasible for all owners.

Millan told the Times that any exercise for dogs is good exercise, including, walking, swimming, running, herding, jumping and search-and-rescue work, though the optimal daily amount needed varies depending on the dog's breed and age. Overall, experts advise against overfeeding your pet, even if your dog tries to guilt you into it, as their health and well-being depends on you.
