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.

Obesity in dogs is a more common problem than you might think. Between 25% and 40% of dogs are overweight, but often, owners don’t realize it until they take their dog to the veterinarian for another reason. Yet even vets can’t tell if a dog is obese by their weight alone. Ideal weight varies by breed, and quite widely within breeds.(Did you know, for instance, that Labrador retrievers, dachshunds and beagles areall prone to obesity?) In short, there’s no ideal healthy weight chart for all dogs!
The good news is that if your dog is overweight, there are a number of ways to help them reach a healthy weight. Don’t underestimate the power of daily walks and a weight management dog diet — IAMS™ Adult Healthy Weight can help return your dog to a healthy weight, providing a path to help keep them fit for life.

Can you feel individual ribs easily? Is your dog’s abdomen slightly tucked up whenviewed from the side? That’s a sign your dog is at their ideal weight.
If you can't feel the ribs easily, your dog has no waist and their abdomen drags,your pup is carrying extra weight. Your veterinarian can help you further evaluateyour dog’s condition and determine their ideal weight.
Dogs gain weight for the same reason people do: They eat more calories than theyuse. Today’s dogs share another problem with their human parents: lack of activity.Many pet parents work all day and are too tired to play with their dog afterward.
Dogs’ metabolisms might slow as they age or after they’re spayed or neutered,which means they require less food. Another common reason for weight gain isfrequently eating high-calorie treats. Sometimes more than one family member isfeeding the dog, and the dog sure isn’t telling!
Other factors that could contribute to canine obesity include:
If you suspect that your dog is overweight or obese, the !rst step is to set up anappointment with your veterinarian so they can evaluate their condition. Likewise,before beginning any weight loss program with your dog, make sure to discuss itwith your vet.
If your dog is overweight, it’s time to implement a weight-management regimen. Ifyou usually feed one large meal a day or keep food available at all times, try adifferent dog-feeding schedule by dividing the daily ration into several small meals— at least two meals a day. It takes energy to digest food, and dividing your dog’sdaily ration into separate feedings will help. If your dog leaves any food in theirbowl, pick it up 30 minutes after each meal.

Your goal is to help your dog be healthier, so select their food carefully. Payattention to the ratio of fat, !ber, protein, carbohydrates and special ingredients inyour dog’s weight-management food:
After your dog reaches their ideal weight, select a maintenance food to keep theirweight steady.
