Part 1: Top 5 Most Common Questions Dog Nutritionists Get Asked (and Expert Answers!)

As a pet owner, your dog’s health and well-being are top priorities, and nutrition plays a big role in both. With so many diets, brands, and opinions on dog nutrition, it’s easy to feel confused. To help clear things up, here are the answers to five of the most common questions dog nutritionists are asked.

1. What’s the best type of food for my dog—dry, wet, or raw?

Choosing between dry kibble, wet food, and raw meals depends on your dog’s individual needs. In general:

  • High-quality dry kibble is convenient, can offer dental benefits through chewing, and provides balanced nutrition.

  • Wet food can be more palatable and hydrating, especially for picky eaters or dogs with dental problems.

  • Raw diets are nutrient-rich but need to be handled and prepared carefully to avoid contamination.

Tip: Always consult your vet or a canine nutritionist before making any major changes, especially if considering a raw diet.

2. How do I know if my dog’s food is nutritionally complete?

Look for food packaging that meets the standards of the Association of American Feed Control Officials (AAFCO). AAFCO-approved food is formulated to be complete and balanced for your dog’s life stage. If you're feeding a homemade diet, consult with a canine nutritionist to ensure it meets your dog’s nutritional needs.

3. How much food should I feed my dog?

The amount depends on your dog’s age, weight, activity level, and overall health. Use the feeding guidelines on the food packaging as a starting point, but bear in mind they’re only estimates. For a more accurate method, consult your vet or nutritionist, who can calculate your dog’s exact caloric needs.
Important: Obesity is common in dogs, so portion control is essential to maintaining a healthy weight.

4. Is grain-free food better for my dog?

Grain-free diets became popular due to concerns over allergies, but unless your dog doges have a grain allergy, they’re not always necessary. Most dogs can digest grains like rice, oats, and barley just fine so there’s often no need to switch to grain-free.
Recent investigations by the FDA have also raised concerns about a possible link between grain-free diets and heart disease in dogs so always consult with your vet before making the switch to be on the safe side.

5. Can my dog eat human food?

Some human foods are safe for dogs, while others can be dangerous and toxic.
Safe human foods include:

  • Lean, cooked meats (unseasoned) like chicken, turkey or beef

  • Plain vegetables (carrots, green beans, sweet potatoes)

  • Fruits (blueberries, apples—without seeds, bananas)

Foods to avoid:

  • Chocolate, grapes, raisins

  • Onions, garlic

  • Anything containing xylitol (found in some sugar-free products)

Always introduce new foods slowly and in moderation.
