Whether your dog is a big sweetie, a big weirdo or a big athlete, here’s what you need to know about taking care of your big dog.
First, all big dogs start out as little dogs. But pretty soon they grow up — and so does their appetite, their toys, their dog bowls, the vet bill and their need for speed.
He started to grow.
And pretty soon
he was bigger than
the recliner.
Sometimes it can take more than two years for them to reach their full size.
And you won’t like to think about it too much, but their life spans are shorter, too: about 10 to 12 years.
No wonder
you'll let him push
you off the bed
at night.
If a large dog gets too much food as a pup, they’re at a higher risk of growing too quickly, which can cause joint trouble.
For large breeds, being overweight is especially problematic. All that extra weight can be a lot for the joints to carry around.
Keep your good old dog healthy by practicing portion control and feeding nutritious food like IAMS™ Mature Adult Large Breed.
How will she catch
a screaming
15-mile-an-hour
Frisbee in midair
if she has knee trouble.
Back in the day, large-breed dogs were especially energetic. They were working dogs, herders, hunters, cart pullers and people protectors.
Who are we to deny their evolution?
Make sure your dog gets exercise every day.
How do you accomplish this? Walk, walk and more walk. And add in some running, jumping, chasing, hiking, fetching, dog-park visiting, swimming and even agility courses.
Repeat this mantra:
'I am the alpha.'
When it comes to training, think of it this way: The bigger the dog, the harder it is to hide behavior problems. And if you can’t control your super-sized soulmate, they could inadvertently cause damage or hurt someone.
Living large is all
about biting the
wind and living
that sweet,
sweet life.






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.
Learn more about how you can help your senior dog manage common health issues associated with aging.
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.*
