Frequently asked questions
Why choose grain-free dog food?
Some dogs have allergies or sensitivities to grains like wheat or corn. Grain-free diets replace these with alternative carbohydrates like sweet potatoes or peas, which can be easier to digest for some dogs.
Is grain-free dog food safe for all dogs?
Most dogs can enjoy grain-free food, but it's important to consult your veterinarian, especially if your dog has a history of heart disease, as some studies have linked grain-free diets to dilated cardiomyopathy (DCM) in certain breeds.
How do I know if my dog needs a limited ingredient diet?
Signs of food sensitivities include chronic itching, ear infections, or digestive upset. Our team recommends trying a limited ingredient diet for at least 8 weeks to see if symptoms improve.
Can these foods be mixed with wet food?
Yes, mixing dry and wet food can add variety and moisture. Just be sure to adjust portions to avoid overfeeding.
What should I look for in the ingredient list?
Look for a named protein as the first ingredient, whole food sources of carbohydrates, and added vitamins and minerals. Avoid artificial preservatives, colors, or flavors.
