What should I feed my Puppy or Kitten?

Figuring out the right diet for your new pet can be overwhelming. With so many brands and types of pet food on the market, it can be difficult to determine which contain the best nutrition for puppies and kittens. Puppies and kittens have different nutritional needs than their adult counterparts, and require a strong foundation to help prevent future diseases and obesity.

Most puppies and kittens are weaned by the time they arrive in their new home at 7 to 9 weeks of age. At this time, nutrition for puppies and kittens must be formulated to support the growth and development of a new pet. Plus, the nutrition needs will change over the course of the first year and when the puppy or kitten matures into a full grown dog or cat. Cats and small/medium sized dogs will reach maturity from approximately 9-10 months, while large and giant breeds of dog will reach full size and maturity between 18-24 months.

  1. A Balanced Diet Is Even More Important for Growing Animals than for Adults

All animals, regardless of age, need a balanced diet to thrive, but puppies and kittens are especially sensitive to nutritional imbalances.

One example is calcium, an essential dietary mineral that plays a critical role in bone development.  If deficient, the bones will not develop properly.  But in excess, calcium can cause a puppy to develop severe bone changes and orthopedic disease. Large and giant breed puppies are particularly sensitive to this.  A properly balanced diet is essential.

  1. Puppies and Kittens Should Not Be Fed Adult Formula Food

Because they are sensitive to nutritional imbalances and their energy needs are greater, puppies and kittens should only be fed a growth formula diet.

Growth places the highest energy and nutrient demands than any other life stage on a dog or cat, apart from lactation. The energy needs of a puppy/kitten are two-fold: 1) support the tissues already developed and 2) provide the energy required to form new tissues.

Puppies& kittens use about 50 percent of their consumed energy for maintenance and 50 percent for new tissue development in the early growth phase. As they get older, the energy needed to support growth diminishes and proportionately shifts to support maintenance. Energy is provided by protein, fat, and carbohydrates. Thus, growth diets often provide a greater percentage of protein and fat to support growth than do adult maintenance diets. Growth diets also provide optimal amounts of calcium, phosphorus, copper, and essential fatty acids, which have an important role in bone formation and maturation, cartilage maturation, hair color, red blood cell development, and trainability.

  1. Unchecked Growth Can Be Harmful to a Dog’s Bones

Feeding a puppy to maintain her ideal body condition promotes the optimal rate of bone development.

The adult weight and size of the animal is not impacted by whether the growth rate is rapid or slow, however, the risk of skeletal deformities increases with rapid growth.

Determining a puppy’s body condition score (BCS) is a reliable way to determine normal growth rate. Body scoring helps you gauge if your dog is maintaining a healthy muscle mass and body fat index. It’s something you can practice at home, using your hands and visual observation.  Ask us to show you how.

  1. Young Animals Need Multiple Feeding Times to Thrive

Animals rely on reserves for energy in between meals. These energy reservoirs are stored glycogen in the liver or fat deposits throughout the body. Ketones produced by the breakdown of fat or amino acids from muscle can also provide energy.  As young animals often have limited reserves and are at risk for the development of hypoglycemia (low blood sugar), multiple meals offered throughout the day best averts the onset of lethargy, trembling, weakness, lack of coordination, and seizures.

Puppies & kittens should be offered at least three meals per day until they are 4-6 months old.  This should be accompanied by close monitoring—with your veterinarian—of body weight, muscle condition, and BCS.

  1. Nutritional Needs Differ by Breed Size

There are a few key differences in the nutrient needs of large breed puppies as compared to small- to medium sized breeds. Most of these focus on reducing the risk of developing orthopedic disease.

Although the development of musculoskeletal disorders is multi-factorial and a complicated disease process, it has been correlated nutritionally with imbalances in calcium, phosphorus, the calcium-phosphorus ratio, vitamin D, and energy intake. Large breed growth diets contain a little less than 1 percent calcium and more than adequately meet the growing large breed puppies’ calcium requirement.  Be sure to feed your large breed puppy one of these diets. Small- to medium-sized breeds are less sensitive to slightly overfeeding or underfeeding calcium, and as a result, the level of calcium in foods for these puppies have a broader margin of safety.

  1. Feeding Methods are not One-Size-Fits-All

Pet parents have three options for feeding growing puppies and kittens: Free choice, which makes the food available 24/7 (like an all-day buffet); time-limited, where food is out for a set period of time; and amount-limited, where portions are pre-determined.

Each have their own benefits and drawbacks and what is right for one animal may not be the best option for another. Therefore, it is strongly recommended that you have a discussion with your veterinarian about the best feeding option for your growing pet.

  1. It’s About the Nutrients

Many people, due to marketing efforts by dog food companies, put undue emphasis on the ingredient list in diets.  Obviously, we don’t want to feed anything harmful, but if your pet does not have an allergy to a specific ingredient, focus on the nutrients, the amount of protein, carbohydrates, fat, vitamins and minerals.  Choose a reputable manufacturer such as Science Diet or Royal Canin that has done the research to determine what puppies and kittens need and have done feeding trials to prove the nutritional value of their food.  Ask your veterinarian if you have any questions.
