The Zoomies

The zoomies are those sudden, irresistible bursts of full-speed running, spinning, and general chaos that overtake your dog with very little warning. One moment they're calm; the next they've lapped the kitchen three times and are sliding across the hardwood floor with wild eyes.

Zoomies are completely normal. They're thought to be a release of pent-up energy or excitement — common after baths (a stressful experience for many dogs), after being in the crate for a while, after a long stay, or simply at certain times of day when your dog's energy peaks. Young dogs and puppies get them most frequently.

There's nothing to correct here. Clear the furniture, enjoy the show, and let your dog run it out. If zoomies are happening constantly and seem related to frustration or anxiety rather than joy, it may be a sign your dog needs more mental and physical enrichment.

Eating Grass

This is one of the most common questions veterinarians receive from dog owners, and the honest answer is: we don't fully know why dogs eat grass, and it's probably not just one reason.

Some dogs seem to eat grass when they feel nauseated, and vomiting afterward is relatively common — though it doesn't happen every time. Some dogs simply seem to enjoy the taste or texture of grass, especially fresh spring growth. Some may eat it out of boredom or to supplement fiber. Research has not found clear evidence that grass-eating predicts illness.

In most cases, occasional grass-eating is harmless. The concern comes when your dog is eating grass obsessively and vomiting frequently — that warrants a vet visit to rule out gastrointestinal issues. Also be mindful of treated lawns: pesticides, herbicides, and fertilizers on grass can be toxic to dogs.

Sniffing Other Dogs' Rear Ends

To a human, it's bewildering. To a dog, it's the equivalent of an in-depth introduction — like reading someone's entire social media profile in three seconds.

Dogs have an extraordinary olfactory system — an estimated 300 million scent receptors compared to our 6 million. Their sense of smell is estimated to be 10,000 to 100,000 times more powerful than ours. And the anal region of a dog contains glands that release a complex cocktail of chemical information: age, sex, reproductive status, health, diet, emotional state, and individual identity.

When dogs sniff each other, they're not being rude — they're gathering detailed, specific information about who they're meeting. It's a highly functional, socially appropriate canine greeting. Let it happen (unless one dog seems uncomfortable). It's polite in dog culture even if it isn't in ours.

Rolling in Dead Things (or Poop)

This is the one that truly tests the love of even the most devoted dog parent. You've just given your dog a bath. You take them outside for five minutes. They find something — you don't know what, you don't want to know what — and they are rolling in it with pure, ecstatic abandon.

There are several theories. The most widely held is that this is an ancient, instinctive behavior: by masking their own scent with the smell of prey or carrion, ancestors of domestic dogs may have been better able to approach prey without being detected. Some researchers also believe dogs roll in strong-smelling substances to "carry" the scent back to their pack, essentially sharing the olfactory news.

Whatever the evolutionary reason, your dog is not doing this to spite you. They find the smell genuinely appealing — a reminder that their sensory world is extraordinarily different from ours. Prevention is your best tool: watch them carefully outdoors, keep them on leash near tempting situations, and try not to be too heartbroken when it happens anyway.

Scooting

If your dog is dragging their rear end across the floor — the infamous "scoot" — they're almost certainly trying to relieve discomfort in their anal area. The most common causes are:

• Anal gland issues — the anal glands are small sacs located on either side of the anus that normally express when a dog defecates. When they become impacted, overfull, or infected, they cause significant discomfort. This is the most frequent cause of scooting and requires veterinary attention.

• Intestinal parasites — tapeworms and other parasites can cause itching around the anus.

• Allergies — both food and environmental allergies can cause skin irritation in this area.

• Grooming issues — matted fur or fecal matter caught in the fur around the tail base.

Occasional scooting is worth a vet mention. Frequent scooting is worth a vet visit. Don't ignore it — anal gland problems are painful and can become serious infections if untreated.

Staring at Walls or Empty Spaces

If your dog stares intently at a wall, a corner, or empty air, the first thing to do is not panic. There's usually a mundane explanation.

Dogs can hear frequencies far beyond our range — up to 65,000 Hz compared to our 20,000 Hz. They may be hearing something inside the wall (insects, rodents, pipes) that you simply cannot detect. Their sense of smell can also alert them to scents behind walls or in areas you can't access.

However, if wall-staring is new, frequent, prolonged, or combined with other behavioral changes — confusion, circling, disorientation, seeming not to recognize familiar people — it can occasionally be a neurological symptom that deserves a veterinary evaluation. Trust your instincts if something seems off.

Chasing Their Tail

The occasional tail chase is perfectly normal play behavior, particularly in puppies who haven't yet fully figured out that the tail belongs to them. Most dogs grow out of it.

If tail chasing becomes frequent, obsessive, or difficult to interrupt — especially in adult dogs — it may indicate compulsive behavior, which is a recognized condition in dogs analogous to OCD in humans. This is more common in certain breeds (Bull Terriers, German Shepherds). Compulsive tail chasing warrants a conversation with your veterinarian or a veterinary behaviorist, as it can escalate to self-injury.

Humping

One of the most socially awkward dog behaviors — and one of the most misunderstood. Humping is not exclusively sexual behavior, and it doesn't only happen in intact (unspayed/unneutered) dogs.

Dogs hump out of arousal (not exclusively sexual — general overstimulation), excitement, stress, to establish social standing, out of habit, or simply because it was accidentally reinforced at some point. It happens between dogs, with people, with pillows, with stuffed animals. It can be a sign of high arousal that needs management, or it can be a compulsive behavior worth addressing with a trainer or veterinary behaviorist.

Spaying and neutering reduces but does not always eliminate humping, particularly in dogs who developed the habit before the procedure. If humping is disruptive or causing social friction, redirect consistently and calmly every time it starts — and consult a positive reinforcement trainer.

Eating Poop (Coprophagia)

We'll be blunt: this is a real thing that many dogs do, and it is as unpleasant as it sounds. Coprophagia — the consumption of feces — is more common than most people realize, and its causes are not fully understood.

Some dogs eat their own feces; some seek out other animals' droppings. Theories include nutritional deficiencies, digestive enzyme insufficiency, learned behavior (puppies may imitate their mothers, who clean the den), attention-seeking, boredom, anxiety, or simply that some dogs find it palatable in ways that defy all logic.

The first step is a veterinary visit to rule out nutritional gaps, parasites, or medical causes. If health is ruled out, management is the main tool: supervise closely outdoors, clean up immediately after your dog defecates, and redirect firmly when you see them investigating. Certain dietary supplements and additives make feces taste unappealing (to the dog, if not more so to you), and may help in persistent cases.

Licking People Constantly

Licking is one of dogs' primary affectionate behaviors — it's rooted in puppyhood, when their mother licked them to stimulate breathing, to clean them, and to bond with them. Licking a person is often a genuine expression of affection and social bonding.

Dogs also lick because human skin tastes interesting — salt, lotion, food traces. Some lick to seek attention, having learned that licking gets a reaction. And some dogs lick excessively out of anxiety, in which case the licking itself is a calming mechanism rather than a social gesture.

Occasional licking is normal and sweet. Obsessive licking — particularly of surfaces, objects, or their own paws and legs — can be a sign of anxiety, allergies, or pain and deserves a vet visit.

Kicking After Going to the Bathroom

After your dog goes potty, they may do a satisfied little kick of the back legs, flinging grass and dirt with gusto. This is entirely normal.

Dogs have scent glands in their paw pads, and this behavior is thought to deposit additional scent marking beyond what the waste itself provides — essentially amplifying their territorial communication. It's a canine announcement: "I was here." The kicking motion may also spread the scent visually, making the mark harder to miss.

Circling Before Lying Down

This is a deeply ancient instinct that has survived thousands of years of domestication. Dogs' wild ancestors would circle to trample grass, check for hidden creatures, and orient themselves to wind and environment before settling in. Modern dogs do it on memory foam beds in climate-controlled homes.

It's completely harmless and entirely normal. If your dog seems unable to get comfortable, circles excessively, or seems distressed when lying down, that's different — it may indicate pain, particularly in older dogs, and warrants a vet visit.

Sleeping with Their Butt Toward You

It can feel a little insulting. But turning their rear toward you while resting is actually a gesture of trust.

Dogs instinctively keep their eyes toward potential threats. When a dog presents their back or rear to someone, they're signaling that they trust that person to watch behind them — they don't need to. If your dog sleeps with their back or bottom pointed toward you, take it as a compliment. You're their safe zone.

Head Tilting

Perhaps the most endearing behavior on this list — the slow, curious tilt of the head when you speak to your dog. Research suggests a few possible explanations:

Dogs may tilt their head to better localize sound, shifting the position of their ear canal to pinpoint where a noise is coming from. They may also do it to see your face better — dogs read human facial expressions with remarkable sophistication, and for dogs with longer muzzles, tilting the head may improve their sightline to your mouth and eyes. Some research suggests dogs also tilt when they're trying to parse words they recognize from your speech.

Whatever the reason — it's one of the most communicative gestures in the dog playbook. They're paying attention. They're trying to understand you. They're engaged.

Keep talking to your dog. They're listening more carefully than you know.
