Grain-Free vs. Grain-Inclusive Pet Food: Which is Better?
Wellness is launching grain-free kibble diets for cats that provide high-quality animal protein sources, balanced with grain-free carbohydrates, essential vitamins and minerals for whole-body health – catisfaction guaranteed! Each grain-free recipe delivers the great nutrition expected from Wellness Complete Health®, but without the grains.
During this transition we recommend that if you are currently feeding a grained food and will be switching to the Complete Health® Grain Free product line to choose the recipe or life-stage diet comparable to the grained portfolio.

Choosing the right foundation for your pet’s bowl is one of the most important decisions you’ll make as a pet parent. But with the ongoing debate between grain-free vs. grained pet food, it’s easy to feel overwhelmed. Should you choose the ancestral-inspired protein of a grain-free recipe, or the wholesome fiber of ancient grains?
At Wellness Pet, we believe there is no “one size fits all” answer. Both diet types offer distinct nutritional advantages depending on your dog or cat’s unique health profile, activity level, and sensitivities.
Understanding Grain-Free Pet Food
Grain-free pet food is formulated without corn, wheat, rice, or barley. Instead, these recipes utilize alternative carbohydrate sources like sweet potatoes, lentils, chickpeas, and peas.
Best for:
- Sensitivities & Allergies: Dogs and cats with confirmed grain sensitivities often see immediate improvements in skin, coat, and digestive regularity.
- High-Protein Needs: Grain-free diets, like Wellness® CORE®, typically feature higher concentrations of animal protein, making them ideal for high-energy pets or those needing to maintain lean muscle mass.
- Weight Management: By replacing simple grains with complex, fiber-rich legumes, these recipes help pets feel fuller for longer.
Understanding Grain-Inclusive Pet Food
Grain-inclusive (or “with grains”) pet food incorporates wholesome, high-quality grains such as oatmeal, barley, and brown rice. Unlike filler grains used in lower-quality brands, Wellness uses grains that provide essential nutrients.
Best for:
- Digestive Health: Whole grains are an excellent source of dietary fiber, supporting healthy digestion and consistent stool quality.
- Sustained Energy: Grains provide a steady release of energy throughout the day, which is beneficial for the average family dog or indoor cat.
- Heart Health Support: Ingredients like oatmeal and barley provide essential B vitamins and minerals that contribute to a balanced, heart-healthy diet.

Expert Insight: Does My Pet Need Grains?
According to Dr. Erin Schroeder, DVM, the most important factor isn’t just the presence or absence of grains, it’s the overall quality of the ingredients.
“What matters most is the overall formulation and ingredient quality of the diet. The best choice is always the one that supports your pet’s health, energy, and digestion, which is why it’s important for pet parents to work with their veterinarian to determine what’s right for their pet’s overall wellbeing.”
When to Consult Your Vet
If your pet is experiencing chronic itching, ear infections, or frequent upset stomach, it may be time to discuss a diet change. Your veterinarian can help determine if a grain-free Limited Ingredient diet is the right path or if a Complete Health grain-inclusive recipe is more appropriate.
