Panting is when dogs breathe rapidly with their mouth open and tongue hanging out like a slobbery yo-yo. You know what we’re talking about. So other than as an effective method of drool distribution, why do they do it?
Some dogs may occasionally pant when they’re excited or afraid, but the main reason is to help keep themselves from overheating.
In a recent IAMS™ survey,* a majority of dog parents believed that dogs have sweat glands. But dogs don’t sweat like humans do. “We have glands all over our body. Dogs can’t do that,” says Opens a new windowDr. Jo Gale, BVetMed CertLAS MRCVS, Senior Manager, Global Science Advocacy at Waltham Petcare Science Institute. “They have sweat glands on their paw pads, but that’s the only place.” They rely on panting to let out warm air and bring in cooler air. All that drool and fluid in their mouth helps dissipate the heat as well. It’s like a big soggy air conditioner.
Most mammals, and even many birds, pant to regulate their temperatures. Humans are some of the only creatures who cool down by perspiration. Imagine what dogs think of us losing fluid from all over our bodies, sweating through our clothes and needing to wipe our faces all the time. Fortunately, they love us anyway.
Panting is normal, but it expends lots of water, so make sure Fido’s bowl is full of clean, cool H2O, especially during warmer months.
Opens a new windowDr. Tammie King, Applied Behavior Technical Leader at Waltham Petcare Science Institute, suggests “seeking out cool shade, giving them water and stopping physical activity.”
And it goes without saying — but we’re going to say it anyway — that you should never leave your dog in your vehicle on hot days. Even if they’re driving. Which you shouldn’t let them do either.
Some dogs run a higher risk of overheating. “It’s very easy for dogs to overheat on very hot days,” cautions Dr. Jo Gale. “Any dog with a squashed face — bulldogs, pugs, Pekingese — their nasal passages are not able to cool the air as much.” She added that dogs with heavy coats, overweight dogs, and very old or very young pets also can’t control their body temperature as effectively.
If your pooch seems to be panting more than usual or at unusual times, check to see if they’re having trouble breathing, are shaking, or their gums or tongue have noticeably changed color. If so, make sure they have access to water, get them to a cool place and contact your vet.

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.

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.
