Many dog owners should take the time and effort to choose the right food for their canine companions. Some do not realize how the right diet will keep them healthy and free from certain illnesses. Unfortunately, many do not realize that their pooches will have different dietary needs at various stages of their lives. Much like humans, puppies will need more of specific nutrients than adults.

Dog foods are labeled to guide pet owners in finding the right one to feed their pet. If you have a puppy at home, reach for a product that has been rated as “growth” because this type of food is specially prepared for kittens and puppies according to AAFCO or Association of American Feed Control Officials.

At this stage, puppies and kitties are still growing rapidly, which is why they need higher levels of protein and more calories in order to meet growth charts. If these nutritional requirements are not met through their diet, your pet might suffer from stunted growth or worse, may get sick.


Once your pet reaches the adult life stage, it is vital to talk with the vet to discuss changes in the dog’s diet. Unfortunately, many pet dogs and cats suffer from obesity and other nutritional diseases. This is the result of the wrong diet. For example, if you have an adult cat or dog, specifically one that does not get a lot of exercise or lead a sedentary lifestyle, it will end up being obese if you keep giving it food that has been designed for puppies and kittens. Therefore, it is good to look for dog food that has been labeled as “adult maintenance” by the AAFCO.


Just like humans, older pets start to get sicker or have more medical problems as they grow old. Having the right diet is important to keep them at the top of health. For example, senior dogs that suffer from mobility problems might be recommended by the vet to choose foods containing fatty acids like DHA and EPA and glucosamine. In some cases, the right pet food might actually help manage symptoms of a disease or medical condition like heart disease and chronic kidney disease. There is no specific food rating for this life stage, so it is good to go for senior maintenance pet food for your pooch. You may also discuss the specifics of your pet’s nutritional needs and deficiencies with your vet. Take a look at our review of senior dog food for more info.
