Nutritional Needs Overview

Dogs are omnivores with a carnivorous bias. While they can digest some plant material, they thrive on high-protein diets with meat as the primary ingredient. The best diet for your dog depends on their age, size, activity level, and individual health needs.

⚡ Essential Nutrients

Protein
Essential for muscle development and maintenance. Dogs need a minimum of 18% protein for adults, 22% for puppies.
Best Sources: Chicken, beef, fish, eggs
Fats
Provide concentrated energy and support skin/coat health. Should make up 5-15% of the diet.
Best Sources: Fish oil, chicken fat, flaxseed
Carbohydrates
While not essential, they provide fiber and energy. Quality matters — whole grains are better than fillers.
Best Sources: Sweet potato, brown rice, oats
Omega-3 & Omega-6
Essential fatty acids for brain health, coat quality, and reducing inflammation.
Best Sources: Salmon oil, fish, flaxseed

Frequently Asked Questions

How much should I feed my dog?▼
Start with package guidelines based on your dog's weight, then adjust. A healthy dog should have a visible waist when viewed from above, and you should be able to feel (but not see) their ribs. Active dogs need more calories; sedentary dogs need fewer.
Is grain-free dog food better?▼
Not necessarily. The FDA is investigating a potential link between grain-free diets and heart disease (DCM). Most dogs digest grains well, and they are not a common allergen. Unless your vet recommends grain-free for a specific reason, grain-inclusive diets are generally safer.
Can I mix wet and dry dog food?▼
Yes! Many dogs benefit from a combination. Wet food adds hydration and palatability, while dry food is convenient and may help with dental health. Just count the total calories from both to avoid overfeeding.
