A cute video shows a golden retriever puppy annoying his older sister by “booping” her on the nose – a habit he never grows out of.
In the funny clip, younger pup Finn balances on a sofa while sister Xena sits nearby.
He then leans over and whacks her on the face with his paw, leaving Xena looking stunned.
A second clip shows Finn as an adult dog repeating the move on his long-suffering sis, hitting her on the head while she does her best to ignore him.
The trick seems to work and when he hits her twice in quick succession Xena doesn’t even blink and while he may never give up the annoying quirk, at least she doesn’t let it get on her nerves.
The video, which has been “liked” more than 2,800 times, was uploaded onto TikTok by user @goldengirl_xena yesterday.
It was posted with the caption: “Finn always boops his sis.”
Unsurprisingly, dog lovers found the exchange adorable and said as much in the comments.
Some left heart emojis and others simply said “awwww”.
This isn't the only way Finn annoys Xena – a funny montage of videos previously showed him using her as a chair at every given opportunity.
In other odd dog news, this golden retriever was recorded looking completely innocent while its pals seemed hell-bent on burying it alive in a hole they dug in the ground.
And a golden retriever puppy with a love of golf balls looked like it might explode with joy after it got a "hole in one".
Meanwhile, a golden retriever who previously had a reputation for being a bit of a troublemaker changed his tune when his owner got pregnant.
Now the cute pooch won't let the mum and her baby bump out his sight as he "guards" them day and night.
