Most adult dogs should eat two meals a day (puppies often require three or more feedings). A feeding guideline for an adult dog is between 2% - 3.5% of your adult dog's ideal body weight per day. For a growing puppy the percentage will be higher at 10%. A breeder or veterinarian will be able to provide you with the ideal weight of your dog. This is just a guideline and the amount should be adjusted, as needed, if your dog becomes overweight or underweight.
Pet foods that are not loaded with fillers, fats, and carbs like fresh or frozen foods work well. This will take a bit of research though. Feeding raw foods has been shown to help dogs and cats lose weight. These foods are high in meat protein, low in carbohydrates, and less calorie dense than dry food. Overweight pets achieve their ideal weight when switched to a raw food diet because feeding a biologically appropriate diet resets their metabolism and their body is able to absorb and process nutrients more efficiently. Many pet feeds on the market today are loaded with too much fat and unneeded carbohydrates.
According to the Association for Pet Obesity Prevention (APOP), the percentage of adult dogs in the US that are overweight is 58% and 55% of cats are also overweight. The APOP survey also discovered a “fat pet gap,” whereas 90 percent of cat owners of overweight cats and 95 percent of dog owners of overweight dogs inaccurately recognized their pets as falling into the overweight range. Like humans, pets need to be at a healthy weight. Face it people your pets are fat.
Losing weight isn’t easy or fast for pets, particularly cats. If you attempt to have your pet lose too much weight too fast (crash diet), serious medical conditions, including a life-threatening form of liver failure, can occur in less than 72 hours. If your pet is eating large servings of food, cut them down a little each day until you reach an appropriate portion size.
