Dog owners have been left emotional after a viral video explained the reason their pets always seem so joyful – and it has provided people with inspiration going into 2026
There’s one certainty in life – your dog’s tail wagging furiously when you return home after a gruelling shift at work. It’s left some pet owners pondering why dogs seem “perpetually cheerful”, hoping to channel this same vitality as the New Year begins.
Tackling this query, TikTok user StarTalks posted a clip following a conversation with astrophysicist Neil DeGrasse Tyson on the topic. They explained: “Ever wonder why your furry friend seems to radiate joy every time you walk through the door? If you’re a dog owner, you know the overwhelming excitement your pup displays upon your arrival.
“Whether you’re gone for a few hours or just a quick trip to the mailbox, your dog greets you with boundless enthusiasm, tail wagging and ready for some love! But why are dogs so consistently cheerful?
“Dogs have a different concept of time than we do.
“With one dog year equating to approximately seven human years, a 10-year-old dog is actually around 70 in human terms!
“As they age, their time on this planet becomes increasingly limited. This understanding might inform their joyful approach to life, encouraging them to make the most out of each day.
“So the next time you see your dog bouncing with joy, remember: they might just be living for today and embracing every moment.
“As the famous saying goes, ‘Be the person that your dog thinks you are.’ Let’s celebrate the simple happiness that our dogs bring to our lives!”
Reacting to the clip, one viewer shared: “As someone who struggles with depression, a dog is the absolute best animal to have. They’re so happy to exist and their energy is contagious. They’re the best.”
Another added: “I love my dogs! I wish they lived as long as us!”
While a third noted: “This does happen with cats – when they are treated like family.”
Someone else offered their take: “I saw someone else explain this before and makes sense.
“Late night zoomies for dogs – it’s technically Friday or Saturday night to them. Also even if you are home all day the reason they take so many naps.”
One final viewer said: “My dog is happy when I come out of my room. He often chews my door frame off until I let him in to steal my bed.”
