Dog Behaviour: Viral Quirks Decoded

Head Tilts, Tail Wags, and Red Flags: Your Guide to Canine Communication

Social media is flooded with adorable videos of our canine companions doing the strangest things—from head tilts to pre-poop circles. But what does all that viral behaviour actually mean?

To help Australian pet parents separate a harmless quirk from a potential red flag, Hill's Pet Nutrition Australia has consulted the science and psychology behind the internet’s most popular canine trends. The goal is to empower you to understand your dog’s actions and know when to simply enjoy the moment and when to call your vet.

Top Viral Dog Behaviour Themes and Their Meanings

  • The Head Tilt

It’s not just cute; research suggests the head tilt may help dogs better localise sounds by adjusting the position of their ear canals. 

For dogs with longer muzzles, the tilt might be a clever tactic to see around their snouts and get a better view of our crucial facial expressions. 

In most cases, it is perfectly normal and simply demonstrates your dog's attempt to understand you better.

  • Puppy Eyes & Tail Wags
This is an evolutionary advantage at work. Dogs have developed specific facial muscles, giving them the ability to raise their inner eyebrows—creating those irresistible "puppy dog eyes" that wolves physically cannot replicate.

Tail wagging is another sophisticated communication tool often misunderstood. Veterinary behavioural studies show that direction, speed, and height of a wag all convey different messages:

✔️ A broad, sweeping wag generally indicates happiness.

❌ A high, stiff wag might signal arousal or potential aggression.

  • The Door Vigil

For most dogs, this is a touching expression of your dog's bond with you, driven by a surprisingly accurate internal clock that anticipates your return to the ‘pack.’

More than just sniffing and circling, dogs are gathering information about who else has been in the area before they settle, establishing or reinforcing territory through their remarkably sensitive noses.

Intriguingly, research also suggests that dogs often align themselves with the Earth's north-south magnetic axis. While scientists are still investigating why this matters to dogs, it suggests they can detect Earth's magnetic field—a sense called magnetoreception.

  • Rescuers at Heart (The Hero Instinct)
This behaviour reveals a profound canine empathy. Studies suggest dogs can 'catch' emotions from others (a trait known as emotional contagion). When they perceive distress, many dogs instinctively respond with helping behaviours. What’s particularly interesting is that this behaviour appears across breeds and isn't limited to traditional "working" or "service" dogs.

  • Licking Everything

Dogs are naturally grooming creatures. The difference between what's normal grooming and a problem depends on frequency, intensity, and what your dog is licking.

✔️ Normal: Licking paws after walks, occasional face and body grooming, brief attention to minor scrapes or cuts, and mutual grooming with other dogs in the household.

❌ Potentially Problematic: Excessive paw licking, private area licking, and ear grooming may be a potential red flag for underlying issues like allergies, anxiety, or pain.

  • Tail Chasing & Tail Chewing

✔️ Tail Chasing: In young puppies, this is often simple play and is a perfectly normal developmental behaviour. 

❌ However, compulsive tail chasing in older dogs (where they become fixated and spin repeatedly until exhausted or cannot be easily redirected) may indicate OCD or anxiety.

❌ Tail Chewing: This is almost always problematic and warrants investigation. Dogs may chew their tails due to allergies, fleas or parasites, anxiety or stress, or tail injuries.

  • Big Dogs, Small Fears
The surprising psychology here reveals why size and confidence aren't correlated in the dog world. This often stems from early socialisation experiences. 

Dogs who weren't properly socialised during their critical developmental period (roughly 3-14 weeks of age) may find unfamiliar presentations intimidating. A dog who grew up only around similar-sized breeds might genuinely be confused or concerned by a tiny dog behaving assertively.

 The Veterinarian's Perspective


Dr. Ilze Nel, Professional and Veterinary Affairs Manager at Hill's Pet Nutrition Australia, says:

“Social media is filled with viral videos of our dogs’ quirky behaviours. These moments give us a glimpse into their unique world and connect us as a community of pet parents, who are often equally baffled, intrigued, and entertained by it all.”

🚦 Red Flags vs. Green Lights: When to Watch and When to Act

Understanding the difference between a normal behaviour and a concerning one is vital for your dog's health.

🟢 Normal & Healthy (Green Light) Head tilting when listening to you, occasional tail chasing in puppies during play, waiting by the door around your usual arrival time, sniffing and circling before toileting, brief grooming sessions, using 'puppy eyes' to request treats or attention.

🟠 Watch & Monitor (Amber Light) Changes in typical behaviour patterns, increased frequency of previously occasional behaviours, mild licking that's becoming more frequent, door waiting that extends longer before and after your arrival.

🔴 Time to Call the Vet (Red Light) Head tilting accompanied by loss of balance or unusual eye movements, compulsive tail chasing that’s difficult to interrupt, tail chewing creating wounds or hair loss, constant paw licking causing staining or sores, excessive licking of private areas or scooting, straining or changes in toileting habits, sudden fear or aggression that’s out of character.

Dr. Nel adds:

“Seeing these behaviours is more than just entertainment; they are a direct line to our dogs’ instincts and a vital indicator of their overall health and wellbeing. When we learn to see these actions as a rich form of communication, we deepen our bond and our understanding of what our dog needs.’’

💡 When Professional Guidance is Needed

If you notice your dog frequently exhibiting "Amber Light" behaviours, or any "Red Light" signs after a vet visit rules out medical causes, it is highly recommended to seek guidance from a certified professional dog trainer or veterinary behaviourist. 

They can provide tailored advice and positive reinforcement strategies to address complex issues like anxiety, compulsive disorders, or sudden aggression, ensuring a safer and happier home environment for everyone.

To find certified, ethical professionals in your area, consult the registers of organisations dedicated to positive reinforcement and fear-free training:
