We took a close look at what’s actually inside the bag to see how it fuels your growing buddy. Understanding the nutritional breakdown is essential for long-term health.
- Chicken: Sitting at the very top of the list, this provides the essential amino acids your pup needs to build lean muscle as they sprout.
- Brewers Rice & Whole Grains: These aren't just fillers; they offer the complex carbs required to keep a high-energy Husky or Lab zooming around the yard all day.
- Poultry By-Product Meal: While some owners shy away from by-products, our team at Petscarelab notes this is a concentrated source of glucosamine, which is non-negotiable for protecting those heavy-duty joints.
- Fish Oil: Rich in DHA, this helps your pup stay sharp during training sessions and keeps their vision clear as they explore the world.
- Dried Egg Product: A high-quality protein "extra" that’s easy on the tummy and packed with nutrients.
