You've probably noticed your dog trying to steal your cat's food. Cat food appeals to dogs because it's higher in fat and protein than their own food. While it isn't usually harmful for Fido to sneak a bit of cat food on occasion, don't make it a regular habit.
Dog food is formulated from both meats and vegetables, providing a healthy balance for a dog's omnivorous diet. Cat food, which contains a higher meat content and far less plant-derived products, will not meet the nutritional needs of a dog. This lack of essential nutrients, combined with the high fat and protein levels of cat food, can give a dog digestive problems resulting in both vomiting and diarrhea. These symptoms can, in turn, lead to dehydration.
A dog living on cat food can become obese. Obesity often leads to health problems by placing stress on the dog's organs and joints, causing decreased mobility and even exacerbating conditions such as arthritis, heart disease and hip dysplasia. Obese dogs are also prone to diabetes and high blood pressure. Obesity can shorten a dog's lifespan as well as reducing his overall quality of life.
An all cat food diet will raise the fat levels in a dog's bloodstream, thereby increasing his risk of developing pancreatitis. This condition, which is an inflammation of the pancreas, causes a major disruption in the dog's digestive system. It forces enzymes out of the pancreas where they may damage other organs such as the liver and kidneys. Pancreatitis is a painful and potentially life-threatening condition.
Tips for a Stubborn Dog
If your dog refuses to eat dog food, you might want to look into purchasing a different brand. Consult with your veterinarian about which brand would be best for your dog, and be sure to find out if he should be eating dry food, canned food, or a mixture of both. Avoid any brands that include wheat, soy or corn. If your dog is still uninterested in his meals, try mixing in two or three spoonfuls of warm, unsalted chicken broth.
