Section 03
Key Buying Factors
01
Protein Source Quality
Look for named meats like bison, salmon, or lamb as first ingredients. Avoid generic 'meat meal' or by-products.
02
Fat & Omega Content
Large breeds benefit from moderate fat (12-18%) and omega-3s for joints and coat. Check for fish oil or flaxseed.
03
Fiber for Digestion
Grain-free foods often use sweet potatoes or peas for fiber. Ensure 3-5% crude fiber to support stool quality.
04
Calcium & Phosphorus Ratio
For large breeds, calcium should be around 1.2-1.5% and phosphorus 0.8-1.0% to support bone health.
05
Additives & Preservatives
Avoid artificial colors, flavors, and BHA/BHT. Natural preservatives like mixed tocopherols are preferred.
06
Calorie Density
Large-breed dogs need controlled calories to prevent obesity. Look for 320-380 kcal/cup depending on activity.
Section 05
Care, Cost and Maintenance
Transition Gradually
Mix increasing amounts of new food over 7-10 days to avoid digestive upset.
Monitor Weight & Stool
Adjust portion sizes based on body condition. Firm, consistent stool indicates good digestibility.
Provide Fresh Water
Grain-free diets can be higher in protein; ensure constant access to clean water.
Pro tip
When switching to a grain-free diet, we recommend adding a probiotic supplement for the first two weeks to ease the transition and support gut health.
Frequently asked questions

Not all large breeds need grain-free, but many owners choose it for potential allergy relief or preference for higher meat protein.

A named meat, a meat meal, a healthy carbohydrate source (sweet potato, chickpeas), fats, and fiber.
