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.

Your new puppy's first meals at home are very important. Find out what formula your puppy has been eating, and continue feeding this food for a day or two after you bring him home. If you want to change his diet to a premium food such as IAMS™ ProActive Health™ Smart Puppy Original , gradually move him to the new formula and help avoid intestinal upsets by using the following steps:
Day 1: Fill your dog's bowl with 75% of his old food and 25% of IAMS ProActive Health Smart Puppy Original.
Day 2: Mix his former food and IAMS ProActive Health Smart Puppy Original in a 50/50 ratio.
Day 3: Feed your dog a mixture that's 75% IAMS ProActive Health Smart Puppy Original and 25% former food.
Day 4: Feed 100% of IAMS ProActive Health Smart Puppy Original.
To feed a puppy from weaning to 4 months of age, offer a 100% complete and balanced premium puppy formula. To determine each serving size, start with the daily amount recommended by the feeding guidelines on the pet food label, and divide that number by the number of times a day (usually three times) you plan to feed your puppy.
Serve the food at room temperature and remove the bowl within 30 minutes after he's done eating. After four months, you can feed a puppy twice daily on a regular schedule.
Don't add nutritional supplements to your dog's diet. Adding commercial dietary supplements or 'people food' such as hamburger, eggs, cottage cheese, or cow's milk is unnecessary and might even do more harm than good.
