Pet Food & Nutrition Expert Guide: How to Choose the Best for Your Pet
Pets need a balanced diet, but their nutritional requirements vary by species, age, breed, size, and health status. Dogs, as omnivores, can thrive on a variety of foods, while cats, obligate carnivores, require protein-rich diets to stay healthy.
Growing puppies have distinct nutritional needs compared to adult dogs, especially in large breeds. Overfeeding during this stage can lead to lifelong health problems, including joint and bone issues.
This guide covers everything you need to know about choosing the best food and nutrition for your pet, plus expert tips to help you make informed choices.
Key Nutrients for Optimal Health

Proper pet nutrition includes essential proteins, fats, carbohydrates, vitamins, and minerals, each playing a key role in your pet’s health. Here are the most important nutrients to focus on:
- Proteins are essential for building and repairing tissues. High-quality sources, such as chicken, duck, lamb, venison, salmon, and beef, offer excellent biological value. Look for clearly labeled meats (fresh or dehydrated), and aim for dog food formulas with 40–70% animal-based protein.
- Fats provide energy, support cell function, and promote healthy skin, coat, and brain development. High-fat content delivers more energy per gram, aiding mental focus and physical performance. Look for sources rich in omega-3 and omega-6 fatty acids, such as salmon and venison.
- Carbohydrates provide energy and support digestive health. While some grains like corn and wheat may cause sensitivities in certain dogs, brown rice is a gentle, high-fiber option with a low glycemic index.
- Sweet potatoes and regular potatoes are both nutritious sources of carbohydrates, with sweet potatoes often preferred for their lower glycemic impact. However, portion control is important for both.
- Legumes, including lentils, peas, and chickpeas, provide not only carbohydrates but also plant-based protein, fiber, iron, and other essential minerals. While beneficial, they should be introduced gradually and consumed in moderation, as they can cause gastrointestinal discomfort and bloating in some individuals.
- Vitamins and minerals are essential for your pet’s health, supporting bone development, immune response, and metabolic function. Calcium, for instance, plays a key role in maintaining strong bones and teeth.
Deciphering Pet Food Labels
Deciphering pet food labels is essential for choosing the right nutrition for your pet. Understanding ingredient lists and guaranteed analysis helps you make informed, healthy decisions.
Choose pet foods labeled “complete and balanced,” which means they meet nutritional standards set by organizations like AAFCO. This ensures your pet receives all essential nutrients in the right proportions. The ingredients list is crucial when evaluating pet food. Prioritize products that list high-quality animal protein, like chicken or salmon, as the first ingredient.
Be wary of specific terms.
Be cautious with terms like “by-products” and “meals” on pet food labels, as they can indicate lower-quality ingredients. However, some by-products, such as liver, kidney, and heart, are nutrient-rich and can be beneficial when clearly specified.
Keep clear of ingredient splitting.
Ingredient splitting is a labeling tactic where manufacturers divide lower-quality ingredients, such as multiple types of grains or meat meals, to push them lower on the list. This makes less nutritious items seem less prominent, while inflating the appearance of high-quality ingredients.
Avoid excessive fillers.
Avoid pet foods with excessive fillers like corn meal or soybean oil, as they offer limited nutritional value. Steer clear of artificial additives, which may contribute to sensitivities or long-term health issues.
Consult with a vet or a pet nutritionist.
Review the nutritional and guaranteed analysis on the pet food label to understand key nutrient levels like protein, fat, and fiber. This ensures the food aligns with your pet’s specific dietary needs. For added confidence, consult your veterinarian or a pet nutritionist for personalized guidance.
Don't be swayed by advertising or packaging alone.
Don’t rely on packaging or marketing claims. Images of wild animals or words like "natural" don’t guarantee quality ingredients. A brand’s popularity doesn’t always reflect the nutritional value or integrity of its pet food.
Types of Pet Food and Specialty Diets

Different types of pet food offer various benefits and drawbacks depending on your pet’s age, health, and lifestyle. Knowing the options helps you make the best nutritional choice for their well-being.
- Dry food, or kibble, is convenient, cost-effective, and has a long shelf life. Its crunchy texture may help reduce plaque and support dental health. However, its hard texture may not be suitable for dogs with dental or oral health issues.
- Wet pet food is high in moisture, making it beneficial for hydration and often more appealing to picky eaters. However, it is typically more expensive and spoils more quickly once opened. It may be especially suitable for dogs with dental or oral health issues, as well as those that have kidney and urinary tract issues, as its soft texture is easier to chew.
- Raw diets (BARF—Biologically Appropriate Raw Food) include uncooked meat, bones, and organs to mimic a natural, ancestral diet. While some owners prefer this approach, it carries risks like bacterial contamination and nutrient imbalances, so veterinary supervision is essential.
- Homemade pet diets give owners full control over ingredients but can be time-consuming and challenging to balance nutritionally. To avoid deficiencies or excesses, they should be formulated with guidance from a veterinary nutritionist.
- Pets with conditions like kidney disease, obesity, or food allergies may benefit from specialty diets tailored to their specific health needs. These diets should be used under veterinary supervision to ensure proper nutritional balance and medical effectiveness.
- Some studies have linked grain-free and legume-based diets to an increased risk of heart disease ( dilated cardiomyopathy or DCM) in pets, though the exact cause remains unclear. Since true grain allergies are uncommon, diets with whole grains from reputable brands, ideally formulated by veterinary nutritionists, are often a safer choice.
Portion Control and Feeding Practices
Proper portion control helps prevent obesity and malnutrition, supporting your pet’s overall health. Always measure food using a scale or measuring cup, as package recommendations are general and may not reflect your pet’s individual needs.
Regularly monitor your pet’s weight to catch changes early and maintain a healthy body condition. Adjust food portions based on their age, activity level, and overall health. Fresh, clean water should always be available to keep your pet properly hydrated. For cats, adding wet food to their diet can support better daily hydration.
Avoid giving your pet toxic foods like chocolate, grapes, raisins, onions, garlic, alcohol, certain nuts, and xylitol. Even small amounts can cause severe illness or be life-threatening.
Treats should be given sparingly and make up less than 10% of your pet’s daily caloric intake. Opt for nutritious options, as overfeeding treats can lead to weight issues and disrupt a balanced diet.
Introduce new food gradually over a 7–10 day period to minimize the risk of digestive upset. Start with a small amount mixed into your pet’s current food, increasing it slowly each day.

The Indispensable Role of a Professional
A veterinarian or pet nutritionist can provide personalized guidance based on your pet’s health, lifestyle, and dietary needs. They can help determine proper portion sizes, recommend therapeutic diets, and suggest supplements when appropriate.
For complex nutritional needs, consult a professional for expert guidance. Regular check-ups help monitor your pet’s weight, overall health, and how well they’re responding to their diet. Ongoing input from a veterinary or pet nutritionist is key to long-term nutritional success.
By understanding your pet’s nutritional needs, reading food labels carefully, and consulting your veterinarian or pet nutrition expert, you can make confident, informed choices. These decisions help support your pet’s long-term health, well-being, and happiness.
A Final Word
Pets require a balanced diet, but their nutritional needs aren’t one-size-fits-all. Factors like species, age, breed, size, and health conditions play a major role in determining the right food. For example, dogs, being omnivores, can eat a wide variety of ingredients, while cats need high-protein diets due to their status as obligate carnivores.
Meeting your pet’s nutritional needs begins with understanding their requirements and selecting high-quality food that supports their overall well-being. For tailored advice, particularly when dealing with health conditions, consult a veterinarian or certified pet nutritionist. With expert guidance and informed decisions, you can help your pet live a healthy, vibrant life at every stage.
