A golden retriever has captured hearts with his reaction after realising a new puppy would be spending the night at his house. Owner Idalis Bruno, 28, couldn’t help but laugh at her two-year-old dog’s response to discovering another golden retriever was there to stay - and not just a one-time playmate.

In a viral TikTok video, Beau is seen sniffing around the puppy’s crate as Wylder catches up on his sleep after a day of playing with his new big brother. Much to Beau’s horror, it was at that exact moment the penny dropped and he realised he would now have to ‘compete’ for attention from his owners.

Idalis, from Savannah, Georgia, told Newsweek: “What we thought was going to be a cute moment actually ended in uncontrollable laughter as we watched Beau investigate the situation with both confusion and concern.

“His head tilt says it all. He probably thought they were having a playdate until the night officially came to an end and he saw the puppy had fallen asleep in what was once his playpen.”

The video has racked up almost 160,000 views in a matter of days and has 14,000 likes.

Commenting on the clip, one user said: “He’s like, ‘You better wake up, you’re going to miss your bus!’”

Another user added: “What do you mean he’s here to stay?”

A third user said: “Not impressed one little bit.”

One more user added: “Sleep good now ’cause you’re outta here in the morning.”

In a separate clip, the two dogs are seen playing and snuggling up to each other - so it seems Beau has accepted his new brother into his home and heart.

Battersea has shared advice on how to introduce a new dog to an existing dog in the family - and there’s one very important thing you should do before stepping into the house with them.

A statement reads: “When you first get home with your new dog, don’t go indoors straight away. Instead, take both of your dogs for a walk together in an area with lots of open space where they can take their time to explore and get to know one another at their own pace on more neutral ground.

"You may have to arrange for a friend or family member to help by walking one of the dogs so you can give them as much space as they need to relax.

"It’s natural to be excited, but try to be as calm as possible and allow them to interact in their own time. Don’t force them towards each other and don’t pick up either dog or try to push them to say hello, as this could create tension between them.

"Instead, praise any positive behaviours and let things happen naturally. Bear in mind that if you have had a particularly long or stressful journey home, your new dog might need a while to calm down on this walk before they’re in the right mood to calmly and successfully greet your resident dog."

On top of this, you should make sure everything in your house is ready for your new arrival and watch out for signs of stress in both animals.
