Best for
This Diamond Naturals formula is an ideal choice for the budget-conscious owner of an adult large or giant breed dog. If you have a German Shepherd, Labrador, Golden Retriever, or similar-sized companion who thrives on a traditional lamb and rice diet, this kibble offers a fantastic intersection of value and quality. It's particularly well-suited for dogs without grain sensitivities who need a solid, dependable daily diet for maintenance and overall health. For multi-dog households or anyone looking to manage pet food costs without resorting to low-quality brands, this 40-pound bag provides a sensible, economical solution that delivers complete nutrition day in and day out.
Feeding guide
The right amount of food is crucial for maintaining a healthy weight, especially in large breeds. As a general guideline, a dog weighing between 60-80 pounds might require approximately 3 to 4.5 cups of this kibble per day, ideally split into two separate meals. A dog in the 80-100 pound range might need 4.5 to 5.5 cups daily. However, these are only estimates. Factors like your dog's age, metabolism, and daily activity level can significantly alter their caloric needs. Always consult the official feeding chart on the product packaging for the most accurate measurements. For a feeding plan tailored specifically to your dog's health needs, a consultation with your veterinarian is highly recommended.
Ingredients & nutrition note
This formula's foundation is lamb meal and rice. It's important to understand that 'lamb meal' is a highly concentrated protein source, not simply ground lamb. The rendering process removes water, resulting in a product much richer in protein by weight than its fresh counterpart, making it an efficient ingredient for building kibble. The inclusion of rice provides digestible carbohydrates for energy. As stated in the product name, this food is also supplemented with probiotics to aid digestion. While we can highlight these key components, this is not a complete ingredient list. For a full breakdown of ingredients and the guaranteed analysis, you must refer to the information printed on the physical product bag.
