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.

Small-breed dogs tend to have higher metabolism rates than their larger counterparts, which means they need a puppy feeding diet specifically designed for them. 'Small-breed dog food formulas are created to give your dog the right balance of nutrients,' says Debra Eldredge, DVM, a veterinarian in upstate New York and coauthor of The Dog Owner's Home Veterinary Handbook (Howell House). Here's what you need to know to feed your small-breed pooch.
The guidelines on the package are a great starting point, Eldredge says, but 'you have to customize [them] for your dog.' For instance, her family has three dogs who all weigh almost the same. But, one is getting twice as much food as the other two, and she's thin. 'She just burns it up,' Eldredge says. Your dog's breed and activity levels will affect how much food she needs.
Small-breed puppies, especially toy breeds, can be prone to hypoglycemia. To keep your dog’s blood sugar levels up, you might have to feed her more frequently and up the calories, Eldredge says.
Small-breed puppies grow quickly, so during the first six months, they need to eat more food and eat more frequently, generally three to four times a day. After six months, feeding two meals a day is usually sufficient. As your dog gets older and less active, her nutritional needs change, and she may need a formula for mature dogs. Her new food will generally have more protein and fewer calories.
Smaller dogs have smaller mouths and teeth, so their food is usually made in a smaller bite size, which is easier for them to chew and swallow.
Don't leave your dog's food out all day. Instead, pick it up after 10 or 20 minutes, Eldredge says. If food is available all day, she may eat out of boredom.
With dog food, your pet is on a balanced diet. Feeding her human food may throw off that balance. The occasional taste of chicken or eggs is okay, but don't make it a daily habit.
