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.

Puppies grow quickly and have special nutritional needs to keep their bodies strong. The most noticeable time is known as the rapid growth stage, which occurs between 2 and 6 months of age. From about 3 to 6 months, most pups will lose their puppy teeth (you might find a tooth near his dish or on the floor; this is normal).
During this phase, his mouth and gums may be very sensitive, which could cause him to be a bit picky when it comes to eating. There's nothing you can do except to wait it out, even if his appetite is low for a couple of days.
Helpful Hints
Don't switch to a new formula to stimulate your puppy's appetite. Changing food at this time can cause additional stress and intestinal upset. The tips below could help your puppy make the change:
