17 Weird Dog Behaviors Explained

Why Dogs Do Weird Things

Dogs experience the world differently from we do. Their sense of smell is powerful, their social habits are different, and many behaviors that seem odd to people are normal dog communication.

A weird behavior may come from:

• Instinct
• Scent marking
• Play
• Stress relief
• Boredom
• Curiosity
• Discomfort
• Learned habits
• Medical problems

17 Weird Dog Behaviors Explained

Dogs do strange things that can leave us laughing, confused, or a little concerned. From zoomies and grass-eating to rolling in smelly stuff, many weird dog behaviors have real reasons behind them.

1. Getting the Zoomies

Zoomies are sudden bursts of wild running, spinning, or bouncing. The technical term is “frenetic random activity periods,” or FRAPs. They often happen when a dog has extra energy, feels excited, or releases stress.

Most zoomies are normal. Just make sure your dog is in a safe area away from stairs, slick floors, roads, or breakable items.

Call your vet or a trainer if zoomies seem constant, frantic, unsafe, or tied to anxiety.

2. Chasing Their Tail

A puppy may chase its tail because it is curious or playful. Some adult dogs do it for fun or attention.

However, repeated tail chasing can also point to boredom, stress, skin irritation, pain, or compulsive behavior. Frequent tail chasing may need veterinary attention, especially when it is new or obsessive.

3. Circling Before Lying Down

Many dogs turn in circles before they settle. This may come from old nesting instincts, comfort-seeking, or checking the resting spot.

A few slow circles before a nap are usually normal. Repeated circling, confusion, falling, head-pressing, or pacing may mean it’s time to visit the vet.

Circling can also happen during bathroom breaks, but for different reasons. Learn why dogs circle and sniff before pooping, how scent and comfort influence the routine, and when repeated circling may signal a problem.

4. Kicking After Pooping or Peeing

Dogs often kick grass or dirt after going potty. It may look like they are covering the mess, but they are usually spreading scent from their paws and marking the area.

This is normal unless your dog seems in pain, obsessive, or is tearing up their feet.

5. Eating Grass

Many dogs eat grass. VCA animal hospitals note that fewer than 25% of dogs vomit after eating grass, and only 10% show signs of illness before doing so. Grass-eating may relate to fiber intake, boredom, anxiety, or natural scavenging behavior.

Call your vet if your dog constantly eats grass, vomits often, has diarrhea, seems sick, or eats chemically treated grass.

6. Eating Poop

This one is gross, but it is common enough to have a name: coprophagia. A dog may eat poop for behavioral reasons, but you should rule out medical causes first, especially if it starts suddenly.

Dogs may eat poop out of curiosity, scavenging, stress, attention-seeking, habit, or access to yard waste.

This is one reason consistent yard cleanup matters. A cleaner yard gives your dog fewer chances to practice the habit. Poop Free OKC offers professional dog poop removal services when the backyard is hard to keep up.

7. Rolling in Smelly Things

Dogs may roll in grass, dirt, poop, dead animals, or other strong smells. This behavior may come from scent masking, scent collecting, or simple enjoyment.

It is normal, but it is not always sanitary. If your dog keeps rolling in waste, remove the source and clean the area.

8. Scooting Their Butt

Scooting may look funny, but it usually means something is bothering your dog’s rear end. The American Kennel Club lists scooting, excessive licking, straining, and blood or pus near the rectum as possible signs of anal gland problems.

Occasional scooting after a messy poop may happen. Repeated scooting needs a vet check.

9. Humping People, Dogs, or Toys

Humping is not always sexual. Dogs may hump because they are excited, stressed, overstimulated, playful, or seeking attention.

Redirect your dog calmly. Ask for a sit, offer a toy, or move them away from the situation. Call your vet if humping starts suddenly or is accompanied by licking, swelling, pain, or urinary issues.

If mounting becomes frequent, hard to interrupt, or causes problems with people or other dogs, follow our step-by-step guide on stopping your dog from humping using calm redirection, exercise, and reward-based training.

10. Licking People

Dogs lick for many reasons. They may be greeting you, seeking attention, tasting salt on your skin, showing affection, or self-soothing.

Gentle licking is usually normal. Constant licking of people, paws, floors, or furniture may indicate anxiety, allergies, nausea, pain, or a habit.

For a deeper breakdown of affection, attention-seeking, taste, stress, and excessive licking, read our guide on why dogs lick people.

11. Howling at Sirens or Music

Some dogs howl when they hear sirens, music, other dogs, or high-pitched sounds. It may be communication, alerting, or an instinctive response.

Howling is usually normal unless it becomes excessive, occurs when your dog is alone, or is accompanied by signs of separation anxiety.

12. Digging Holes

Dogs dig for many reasons. They may be bored, hot, hunting, hiding a toy, trying to escape, or making a comfortable resting spot.

Digging is normal, but it can become a problem if your dog digs under fences, destroys the yard, or seems anxious. Give them more exercise, shade, enrichment, and supervised yard time.

13. Sleeping Twitches, Barks, or Running Movements

Dogs may twitch, bark, whimper, or move their legs while sleeping. In many cases, they are dreaming.

Let them sleep unless they seem distressed or unsafe. Call your vet if movements look like seizures, happen while awake, or your dog seems confused afterward.

14. Reverse Sneezing

Reverse sneezing sounds like snorting, honking, or sucking air in quickly. It can be alarming, but many episodes pass quickly.

Call your vet if it happens often, lasts a long time, comes with coughing, blue gums, weakness, nasal discharge, or trouble breathing.

15. Staring at You

Dogs stare for several reasons. They may want food, attention, direction, comfort, or permission. Some dogs stare because they are reading your body language.

A soft stare is usually normal. A hard stare, a stiff body, a closed mouth, or a raised posture may signal tension.

16. Tilting Their Head

A head tilt can mean your dog is listening, focusing, or trying to understand a sound.

It is usually adorable and harmless. A constant head tilt, loss of balance, ear pain, circling, or eye flicking should be checked by a vet.

17. Sniffing Butts or Private Areas

Dogs gather information through scent. Butt sniffing is normal dog-to-dog communication. Sniffing people’s private areas is embarrassing, but it is usually curiosity, not bad manners.

Teach a polite greeting cue, such as “sit,” “touch,” or “go say hi.” Reward your dog for greeting guests calmly.

When Weird Dog Behavior Needs a Vet

Call your veterinarian if a weird behavior is:

• Sudden
• Repeated
• Painful
• Obsessive
• Linked to vomiting or diarrhea
• Linked to coughing or breathing trouble
• Causing injury
• Paired with appetite changes
• Paired with low energy
• Getting worse over time

A behavior that is normal once in a while may not be normal when it becomes constant.

The “Bottom” Line: Weird Dog Behaviors Explained

Most weird dog behaviors make sense once we look at the world from a dog’s point of view. Dogs sniff, dig, roll, lick, kick, run, and stare because they are communicating, exploring, relieving stress, or following instincts.

Still, we should pay attention to patterns. If a behavior is new, excessive, painful, or associated with illness, call your veterinarian.

Sudden indoor peeing can feel like a strange behavior, but it often has a real cause. For help with accidents, marking, anxiety, and potty setbacks, read our guide on why dogs pee in the house.
