Dog owners have long believed their pets can tell when they’re loved, and new research suggests they might be right. Scientists and animal behaviour experts say dogs pick up on subtle cues we don’t even realise we’re sending, from shifts in our scent to tiny changes in heart rate and tone of voice.
These signals reveal our emotions more clearly than words ever could, helping dogs form deep, intuitive bonds with their humans.

Their Noses Are Superhero-Level Powerful
Dogs possess around 300 million scent receptors, while humans have only six million. This incredible olfactory system allows them to detect even the smallest chemical changes in our bodies, including shifts in hormones.
Their sense of smell is so advanced that it can pick up on things we can’t even imagine detecting ourselves. When you feel strong emotions, your body chemistry changes slightly, and your dog notices immediately through scent alone.
Oxytocin Leaves A Detectable Trail
When humans feel love or affection, their brains release oxytocin, often called the love hormone. According to popular belief, dogs can actually detect changes in our scent caused by this hormone, helping them interpret our feelings.
While scientists continue to study this phenomenon, it’s widely accepted that dogs are highly responsive to emotional cues. Your pup might not understand the science, but they definitely pick up on the chemical signature of your affection.
A Viral TikTok Sparked The Conversation
A recent TikTok video sent dog lovers into an emotional spiral after suggesting that dogs can smell when we love them. The clip shows a puppy cuddled up with its owner, with on-screen text claiming dogs sense our oxytocin levels and that it makes them happy too.
The comments section was filled with heartfelt reactions. One user wrote, “Love is literally in the air,” while another said, “So she knows how much I love her? Oh good.”
Body Language Speaks Volumes To Them
Beyond scent, dogs are masters at reading human behaviour and body language. They notice your facial expressions, the tone of your voice, and even subtle changes in your posture or heart rate.
This multi-sensory approach means they’re constantly gathering information about your emotional state. Whether you’re feeling joyful, anxious, or affectionate, your dog is likely already aware before you’ve said a single word. They’ve evolved alongside humans for thousands of years, making them uniquely attuned to us.
Trust Forms Through Consistent Actions
Whether or not your dog can smell your affection, they can certainly feel it through your actions. Consistent care, gentle communication, and positive reinforcement all help strengthen the human-dog bond.
Dogs thrive on routine, trust, and affection, so spending quality time together is the best way to show them love in a way they understand. Your daily interactions matter more than any single grand gesture, building a foundation of security and mutual respect.
The Bond Works Both Ways
Many dog owners shared touching stories online about late pets, saying the idea that dogs sense our love gave them comfort. Others were more sceptical, noting that while dogs can detect our moods and physiological changes, they may not literally smell love in the air.
Still, the takeaway was clear: dogs respond deeply to the way we treat them, emotionally and physically. That bond runs both ways, creating a relationship unlike any other in the animal kingdom.
Adoption Means Sharing That Love
For anyone considering adopting a dog, it’s important to remember that ownership is a long-term commitment. Research breeds carefully to find one that matches your lifestyle and energy level.
Adoption centres and animal charities across the UK have many dogs looking for homes, and each one is capable of giving that same unconditional love back. When you open your heart to a rescue dog, you’re offering them the chance to finally sense the love they deserve.
