DHA (docosahexaenoic acid) is an omega-3 fatty acid important for neural development of puppies. DHA is a major structural component of the brain, as well as the most abundant fatty acid in the brain. It plays a vital role in the development of a puppy’s central nervous system and retinal function.
To help your puppy be as smart and healthy as possible, DHA should be an essential component of your dog's diet. The DHA in IAMS™ ProActive Health™ Smart Puppy food helps encourage healthy brain development, which can make your puppy more trainable and help forge a stronger bond with you.
Common dietary DHA sources include fish (such as salmon, sardines, tuna and other seafood), eggs and organ meat. In pet foods, sources of DHA include fish, fish meal and fish oil.
Prior to weaning, puppies get DHA from their mothers. The puppy’s mother transfers DHA from her body tissues to her offspring during pregnancy and lactation.
After weaning, puppies can obtain DHA through their diet.
One IAMS study looked at beagle puppies whose mothers had been fed enhanced or typical dietary DHA from breeding on through weaning.* After weaning, puppies were fed the same diets as their mothers throughout the remainder of the study (up to 16 weeks of age). To evaluate the effect of diet on trainability, all puppies were taught to associate a symbol with a direction in a t-maze, with correct responses resulting in a food treat.
In the 30 days of testing, puppies from the enhanced-DHA group consistently outperformed the puppies from the typical-DHA group on the maze test. Results of the study indicated that puppies nourished on high DHA levels were more trainable.

Providing pets with vitamins, minerals, and other nutritional components is important to pet health and well-being, and the best way to do this is to feed a high-quality, complete, and balanced diet. Supplementing dog food often upsets the balance and might cause health problems.
People supplement their dog's diet for different reasons:
It is important to know that a quality dog food is carefully formulated to meet the caloric needs of the animal. The food provides essential amino acids, vitamin-rich fish oils, and minerals specific to the nutritional requirements of the dog.
Quality foods are complete and balanced for a specific life stage or lifestyle. Adding table scraps or other supplements can disrupt the delicate nutrient balance.
The interaction between minerals is very complex. Fortunately, this area of nutrition has been the focus of extensive research for many years. Research has shown that not only are the individual levels of minerals in a diet important but the proper balance is also. An excess of one mineral might affect the absorption of a second, and lead to a deficiency in that second mineral.
One common way of supplementing is to feed extra meat. However, because meat contains 20 to 40 times more phosphorus than calcium, adding meat to a balanced diet will upset the calcium to phosphorus (or Ca:P) ratio, which is important for proper bone development and maintenance.
This might prompt your pet's body to absorb calcium from the bones in order to reach the right balance. This is often the case in older animals that experience tooth loss due to the reabsorption of bone from the lower jaw. Ca:P ratio should range between 1.1 to 1.4 parts of calcium for each part of phosphorus.
Excess amounts of calcium have been associated with several bone diseases affecting growing puppies. Owners of large-breed puppies, in particular, believe that their puppies require extra calcium for proper development of large bones. Adding yogurt, cottage cheese, or calcium tablets to the puppy's diet will only upset the body's delicate mineral balance.
Remember: Large-breed puppies consume more food and get the calcium their bodies need by eating the recommended portions. The best way to support a normal growth rate is to feed growing dogs a balanced diet using a portion-controlled regimen.
The Association of American Feed Control Officials (AAFCO) regulates the pet food industry and has established certain nutritional requirements for dogs. These requirements are published annually in the AAFCO Manual. Only pet foods that have met the strict criteria established by AAFCO can carry the 'complete and balanced' statement on the label.
