In the past, veterinarians recommended diets for senior dogs largely based on the nutritional management of diseases common to the aging process. Research, however, has shown that special nutrition can help manage body-condition problems in aging dogs, such as obesity and loss of muscle mass. Senior dogs also benefit from special nutrition to help maintain bone and joint health.

Senior dogs tend to gain weight, despite consuming fewer calories, due to changes in their metabolic rate. Therefore, they can benefit from eating a diet with reduced fat levels and lower caloric density than adult maintenance foods.
Recent IAMS™ research in dogs also indicates that L-carnitine — a vitamin-like compound made in the body from the amino acids found in red meats, fish, chicken and milk — can help reduce weight in overweight dogs by escorting fat into cellular mitochondria where it is turned into energy.
Protein is the building block of muscle tissues. It is important for maintenance of muscle tissues, muscle strength and mobility. Recent research conducted by The IAMS Company has shown that senior dogs that eat a higher-protein diet better maintain muscle protein stores. By providing optimal protein levels from muscle maintenance, we can help senior dogs continue being physically active.
This research is contrary to conventional opinion that senior dog foods should contain lower protein levels than adult maintenance formulas to avoid progressive decrease in kidney function. However, senior dogs fed a high-protein diet had stable renal function and a lower death rate than dogs fed a lower-protein diet.*
During the aging process, cartilage between joints often begins deteriorating. Nutritional management can help maintain healthy bones and joints and mobility in dogs in several ways:
Some pet-food manufacturers have endorsed reduced levels of calcium and phosphorus based on the belief that excesses of these minerals are harmful to the kidneys. However, research has shown that no damaging accumulation of calcium or phosphorus was found in the kidneys of older dogs fed diets containing maintenance levels of calcium and phosphorus for four years.*

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?
