If you’ve got a big love for big dogs, IAMS™ has a large-breed puppy formula specially made for their nutritional needs.
Many large-breed puppies have a tendency to grow very quickly. Unfortunately, if this tendency is encouraged by overfeeding, developmental bone problems can occur. To avoid these problems, careful feeding management is necessary. This should include
- Consideration of optimal protein quantity and quality
- Restriction of the energy-containing fat
- Careful control of the calcium and phosphorus levels
Our specially formulated large-breed puppy formulas make feeding management easier because they are designed for fast-growing, large-breed puppies (those with an expected adult weight of more than 50 pounds).
Protein in Puppy Food
A protein level approximating 26% in these formulas promotes healthy body condition and balances the protein with the reduced number of calories in the food. Research has shown that
- Dietary protein levels from 15 to 32% have no adverse effect on skeletal development.1
- Body condition decreases as protein gets too low.
The protein in our large-breed puppy formulas supports normal skeletal and muscular growth.
Calories and Fat in Puppy Food
Fat contributes more than twice as many calories in a diet as proteins or carbohydrates do. As the fat level increases, the energy content of the diet also increases, making feeding management more difficult for large-breed puppies. Several studies have shown increases in developmental bone problems when a diet was overfed.2, 3
By reducing the fat content of large-breed puppy formulas to about 14%, the metabolizable energy (ME) of the diets can be kept to a low level of about 1,800 kilocalories per pound.
Calcium and Phosphorus in Puppy Food
Fat contributes more than twice as many calories in a diet as proteins or carbohydrates
Comparing with Our Other Puppy Foods
Our large-breed puppy formulas, such as IAMS ProActive Health™ Smart Puppy Large Breed, are made specifically for growing puppies with expected adult weights of 50 pounds or more. These puppy foods are unique because they are formulated with:
- Less fat for fewer calories to optimally reduce growth rate of large-breed puppies and help safeguard against overconsumption of energy
- A lower level of protein to ensure a proper balance of protein with energy content
Reduced calcium and phosphorus levels with a normal calcium-to-phosphorus ratio to promote proper bone development in rapidly growing large breed puppies.
