Panting, bad breath, head shaking: when a normal habit stops being normal

Every list of pet symptoms has the same flaw. It tells you what to look for, then leaves you alone with the hard part, which is deciding whether what you are looking at is a problem at all.

A dog pants. A dog's breath smells. A cat vanishes under the bed for an afternoon. All three are ordinary. All three are also, sometimes, the first thing an owner noticed. What separates the two cases is rarely the behavior itself. It is the context: when it started, whether it happens at rest, whether it is getting worse, and whether it is normal for that animal in particular.

So this page does the sorting rather than the listing. Six signals, each split into three columns: expected, worth a closer look, and call now. Every criterion comes from guidance Petcube publishes on its own site, and each section says where.

Petcube's own guide to panting compresses the whole method into one sentence, and it works for every signal below:

When your dog pants abnormally fast or hard but isn't excited, hasn't exercised, and the temperature isn't hot, there is likely a medical cause. Petcube, When is Dog Panting Abnormal?

Three tests hide inside that sentence. Is there an explanation in the room? Is this new? Is the animal at rest? Hold on to them. They are the only tools this page uses.

Signal onePanting and fast breathing

Is your dog's panting normal, or is it telling you something?

Dogs do not sweat the way we do. Panting is the cooling system, which is why panting after a walk, on a hot afternoon, or in the thirty seconds after you come through the door is the system working exactly as designed.

Some dogs also run loud by construction. Petcube's guide lists pugs, shih tzus, bulldogs, French bulldogs, affenpinschers, Boston terriers, chow chows, boxers and Cavalier King Charles spaniels among the breeds known for loud, snuffling or fast breathing. For those dogs, noisy breathing is a baseline, not a change. The whole exercise is about detecting change.

Figures published by Petcube in its panting guide. The number that matters is not the average, it is your own animal's, measured twice.

A few details are worth writing down when you count. Petcube's guide flags a dog stretching its neck out to breathe, an upward curling tongue, a change in gum or tongue color, and fatigue as the things to note alongside the panting itself. And it links constant panting at night to conditions including Cushing's disease, arthritis and hypothyroidism, which is a fair summary of why night panting deserves more attention than daytime panting.

Fast breathing during sleep can simply be REM. Dogs dream, and dreaming dogs breathe irregularly. Long stretches of it, night after night, are a different thing.

Signal twoBreath, gums and a change in chewing

Bad breath, a different way of chewing, or irritated gums are easy to overlook.

Dog breath is a joke until it is a symptom. Petcube's guide is blunt about the base rate: most cases of bad breath come down to poor oral hygiene or periodontal disease. Plaque and tartar build up, bacteria follow, and over time that can turn into gum disease, cavities, infections and abscesses. None of that announces itself. It just smells.

What makes this signal unusually readable is that the smell itself carries information. Petcube's guide sorts it:

Source: petcube.com, Does Your Dog's Breath Stink?

One practical warning from the same guide, because it gets people every year: human toothpaste can contain xylitol, which is toxic to dogs. Brushing is right. Brushing with your own tube is not.

Signal threeHead shaking and one ear being scratched

Frequent shaking, scratching one ear, or a slight head tilt.

Occasional head shaking is so normal that most owners never register it. Petcube's guide draws the line at frequency and suddenness: a dog that starts shaking its head a lot, all of a sudden, is a dog with something in or on its ear. The list of causes is short and mostly treatable. Ear infection, an allergy, ear mites, water trapped after a swim or a bath, a foreign object, an aural hematoma, or a growth.

There is a home check, and it takes four seconds. Lift the ear flap. Redness, swelling or discharge points to an infection. The guide is careful to add that an infection can sit deep in the canal with nothing visible from outside, so a clean looking ear does not close the question. Dogs also have longer ear canals than we do, which is why water gets in easily and comes out badly.

The distinction worth remembering is between a shake and a tremor. A head shake is something the dog chooses to do. A head tremor, as their guide puts it, is something the dog cannot control. Tremors that appear suddenly go straight to the third column.

One more reason not to wait it out: shaking hard enough, long enough, can burst a blood vessel in the ear flap. The flap then swells, feels hot and droops, which is the aural hematoma their guide describes, and it is a second problem caused by the first.

Signal fourSkin, scratching and paw licking

Red spots, bumps, repeated scratching, paw licking.

Itching is not a malfunction. Petcube's guide, medically reviewed by Ivana Crnec, DVM, describes it, quoting a 2023 study on itchiness in dogs, as a reflex mechanism that can be considered a first line of defense. The problem is not that a dog scratches. The problem is excess, and the guide is specific about why excess matters: it causes self-inflicted injuries, it raises the risk of secondary skin infections, and it damages hair follicles, which is where the bald patches come from.

Sequence matters here more than anywhere else on this page. After a flea treatment, a few days of continued itching is expected, because flea allergy dermatitis is a reaction to flea saliva rather than to the fleas still being there. If it has not settled after that, the same guide lists what a vet then works through: bacterial and fungal skin infections, environmental, contact or food allergy, atopic dermatitis, hormonal imbalances, and stress.

Grooming has its own window. Irritation from hot or dull clipper blades shows up on the face, groin and genitals, and post-grooming furunculosis, as the guide quotes Julie Buzby, DVM, usually appears in the first 24 to 48 hours after a groom. If the itch started the day after the groomer, that is not a coincidence, and it is also not something to sit on for a week.

Keep daily logs of the dog's itch level. Use the Petcube Pet Camera to monitor scratching and itching habits while not at home. Petcube, Natural and Vet-Approved Treatments for Dog Itching, medically reviewed by Ivana Crnec, DVM

That instruction is the honest one, and it is the reason the second half of this page exists. Nobody can log an itch level they never saw.

Signal fiveA cat that hides, drinks more, eats less

Hiding more often. Picky eating. Excessive thirst.

Cats are the hardest animals on this list to read, and Petcube's guide starts by defusing the obvious mistake: hiding is not a symptom. It is essential cat behavior. Every cat should have a spot, and a cat that uses it is a cat doing its job.

The signal is the change. A cat that has always been social and suddenly will not come out is telling you something, and their guide sorts the causes into illness or pain, stress, and pregnancy. The stress list is more mundane than people expect: a move, a new pet, a new baby, thunder, a lawnmower, or nothing more dramatic than you starting work an hour earlier.

Illness rarely travels alone. Their guide points out that hiding driven by illness usually arrives with company, most often loss of appetite or diarrhea, which is exactly why those three signs belong together rather than apart. One of them is a shrug. Two of them at once is a pattern.

Cats don't show their feelings well, so a cat in pain won't look any different than normal, but their behavior and body language can provide clues. Petcube, Crouching Tiger, Hidden Kitty

And the instruction almost everybody gets wrong: do not drag the cat out. Their guide is direct about it. Forcing a frightened or unwell cat out of its safe place makes the fear worse and damages the trust you will need in an hour, when you actually do have to put it in a carrier.

Signal sixHeat, and the one signal with no middle column

One minute your dog is enjoying the summer. The next, something feels wrong.

Heavy panting, weakness, drooling or unusual behavior on a hot day is the one item on this page that does not get a wait and see column. Petcube's guide states it plainly: heatstroke in dogs is a medical emergency that requires urgent treatment, and it can be fatal.

What to do while you are calling, as their guide reports the American Veterinary Medical Association's recommendation: move the dog to a cooler, shaded area and cover them with towels that have been soaked in cold water and then wrung out. Showering with cool water works too. The point is to start cooling before you arrive, not after.

The part nobody writes down: you were not in the room

Look back at what every middle column asked for. When did it start. Does it happen at rest. Is it getting worse. Is it new for this animal. Not one of those questions can be answered from the ten minutes you spent looking at your dog after work. They all require having watched while nothing was happening, which is precisely the time nobody is watching.

This is the gap Petcube's hardware exists to close, and it is worth being concrete about what it actually does. The Petcube Cam records at 1080p through a 110 degree lens with 8x digital zoom, and switches itself to night vision in low light, with visibility up to 30 feet in the dark. Two way audio runs full duplex, so you can hear the room and speak into it.

The alerting is the part that turns footage into a diary. Petcube's own description: audio recognition that knows barking from meowing, detection that tells a pet from a person, motion zones you draw yourself so a restricted corner of the room raises a flag, and emergency alerts if glass breaks or a fire is detected. Their Cam page also offers something closer to this article's purpose: choose from fifteen behaviors you are concerned about, and get told when they happen.

And then there is the feature that most closely matches what the itching guide asked for. Petcube Care compiles the day into a thirty second Daily Diary from the moments with the most activity. It is sold as a nice thing to receive, which it is. It is also, incidentally, a scratching log, a panting log and a hiding log, delivered daily without anyone having to remember to keep one.

Three cases Petcube publishes on its own site

All three are reproduced from the Petcube homepage and the Petcube Care page. Note what they have in common: in every case the owner was somewhere else, and the alert is the only reason there was a decision to make at all.

The other half of the answer, at eleven at night

Watching gets you the facts. It does not get you the verdict. And the middle column, by definition, is the column where you are not sure, which is a bad time to be alone with a search engine.

Petcube's Online Vet is a chat with a licensed veterinarian, running around the clock, for $9.99 a month with unlimited conversations. The detail that makes it credible is in their own FAQ: the vets are certified practitioners currently working shifts in a physical clinic, who take chats between appointments. Their published average wait for a first connection is under three minutes. The service covers cats and dogs.

It is worth being equally clear about what it is not, because Petcube states this itself rather than burying it. Online vets cannot prescribe prescription medication, and they cannot perform a physical examination or run tests. What they can do is look at your photos and video, ask for the history you have been keeping, and tell you which column you are actually in.

Which, for the entire length of this page, has been the only question.

That is the piece the camera and the chat only supply together. A written description of a seizure is a guess about what you half saw. A thirty second clip of it is evidence, and the vet on the other end reads it in seconds.

The arithmetic Petcube publishes

Their Online Vet page makes a claim worth quoting because it is falsifiable and they put a number on it: sixty percent of vet visits could be just a chat. Here is the comparison exactly as they publish it.
