Step 1: Does the manufacturer meet the World Small Animal Veterinary Association Guidelines on Selecting Pet Foods? There are more than 200 different manufacturers selling pet food in the United States and Canada so the choices can otherwise be overwhelming! I identified several of the manufacturers that meet these guidelines so that my friend could feel confident he was feeding a food made with strong nutritional expertise and rigorous quality control.
Step 2: From the manufacturers I identified in Step 1, I then narrowed down their foods I could find online or in stores to those that meet puppies’ nutritional requirements. My friend prefers to feed dry food, so I focused only on dry options, but from just these few manufacturers, I found more than 50 different over-the-counter dry foods marketed for puppies. In addition, there were another 10 that were “all life stages” dog foods that also meet puppies’ specific nutritional needs. “All life stage” dog foods – which may or may not be marketed as such – meet the requirements for both puppies and adults (read more on how you can tell the difference). This meant that I now had more than 60 diets to choose from!
Step 3: Double check that the food is nutritionally complete and balanced, meaning it is designed to meet all the Association of American Feed Control Officials (AAFCO) minimum levels for growing puppies and avoid exceeding AAFCO maximums. This can be determined by reading the nutritional adequacy statement on the label.
Step 4: Has the puppy food undergone feeding trials? Whether a pet food is nutritionally complete and balanced can be determined by feeding trials or by formulation. You can figure out which method has been used by reading the label’s nutritional adequacy statement. Feeding trials are ideal but if the food has “passed” Steps 1-3 above, a “formulated” diet (which hasn’t gone through feeding trials) should be fine as well.
Step 5: Individualizing the diet for your puppy.
Kibble size and shape. Most puppies can eat standard-size puppy kibble, but some smaller puppies may prefer a smaller kibble size. Similarly, certain breeds with shortened noses (brachycephalic) may find specially-shaped kibble easier to eat.
Calorie density (calories per cup or can, which is required information on all pet food labels). Daily calorie needs depend on many factors, including your puppy’s breed, weight, activity level, age, whether they are neutered, and individual personality. Calories in the 60 or so puppy foods noted above ranged from about 300 calories per cup to more than 500 calories per cup! A puppy that is not very active or that tends to get overweight easily should eat a lower calorie food while a puppy that is very active or has a hard time maintaining weight might do better with a food that has more calories per cup.
With any puppy food, it’s also critical that you feed the right amount. It’s reasonable to start with the amount of food recommended in the feeding directions but you often need to adjust that amount, especially as your puppy goes through growth spurts. Feeding directions vary widely among manufacturers, so some feeding directions will be closer to your puppy’s true calorie needs than others. And every puppy is an individual in terms of their calorie needs so, as always, it’s very important to adjust the amount of food to maintain a trim body condition score (4 to 5 on a 9-point scale) throughout your puppy’s lifetime, but especially while growing!
Note that spaying or neutering reduces your puppy’s calorie needs up to 30% so you should reduce the amount of food at the time of this surgery to keep your puppy trim and healthy (but continue to feed a puppy food until they’re 12-18 months of age).
Medical issues. Puppies are sometimes born with heart, kidney, or liver problems or develop medical issues that require a special therapeutic diet. It can be tricky to find therapeutic diets that meet all the nutritional needs of a growing puppy or kitten so, in these cases, I recommend working with a Board Certified Veterinary Nutritionist®.
Other nutrients. I find that pet owners spend a lot of time looking for a certain percentage of protein on a pet food’s guaranteed analysis. Puppy foods made by manufacturers with strong nutritional expertise and rigorous quality control will have the right levels of nutrients for healthy puppies (if you’ve selected the right diet according to these steps), so you don’t really need to worry about the specific nutrient levels for a healthy puppy.
Step 6: Final considerations
Ingredients: Until the specific cause of diet-associated dilated cardiomyopathy (DCM) is fully understood, some owners wish to avoid peas, lentils, chickpeas, potatoes, and sweet potatoes. Other than this, you don’t need to spend time scouring the ingredient list!
The nutritional value and quality of pet food is not necessarily related to its cost. There are some excellent pet foods that can be purchased at grocery stores, and not all expensive foods are in your dog’s best interest.
