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.

We asked dog owners* how many hours a day they think their adult dog sleeps. The answers averaged around 9.7 hours. Truth is, dogs normally sleep around 12-14 hours a day. (Cats sleep 12-16 hours, which is why it’s called a “catnap,” we presume.) “Normal” can depend on lots of things. Bigger breeds definitely need more z’s. Older dogs tire quicker and sleep more. Growing puppies need up to 20 hours a day. Being cute must really be tiresome.
But why do they sleep so much? We’re not going to let sleeping dogs lie; we’re getting to the answers.
Dogs spend less time in deep REM sleep, so they’re able to wake quickly and be ready to go — whether it’s responding to danger or the opening of a bag of chips. It also means they need to doze more often to make up for that lack of truly restful sleep.
In general, carnivores need more rest. “In their wild dog and wolf days, it was a hunt for food, bringing down large prey, then feasting,” says
Opens a new windowDr. Jo Gale, BVetMed CertLAS MRCVS, Senior Manager, Global Science Advocacy at Waltham Petcare Science Institute. “They’d spend a long time digesting and may not eat for a few days. There’s a tendency to conserve energy.” Just think about how you feel after eating a huge steak. Incoming meat coma. Goodbye, belt. Hello, sofa.
Yawn. When owners are out of the house, dogs often sleep simply because they’re bored. They’re not into books and haven’t quite figured out how to turn on the TV, so why not catch a few extra winks? Plus, they want to be super refreshed when you come back home in the evening.
Some dogs like to sleep longer and some dogs are just lazier than others. According to
Opens a new windowDr. Tammie King, Applied Behavior Technical Leader at Waltham Petcare Science Institute, “You might see more sleeping after intense exercise or they’ve gone to a pet sitter or boarding center due to high stimulation.” There’s usually no cause for concern unless they seem lethargic and lose interest in playing or eating, or begin listening to a lot of emo music.
Their wild days long gone, dogs have adapted their sleep schedules to match humans’ sleep schedules. Sort of. They still might get you up in the night or early morning before your alarm goes off. It’s best to exercise them in the morning and evening so they’re more tired — and have used the facilities — right before everyone else goes to sleep.
Now, the only question remaining is, what do you think your dog dreams about?
