Seven minutes is not a particularly long time. But for those who watch the hit television series, “Bluey,” the time span has been a familiar episode length through the show’s past three seasons.

However, a special episode of “Bluey” — which follows the life of the 7-year-old Blue Heeler puppy Bluey Heeler and her little sister, Bingo, her mother, Chilli and her father, Bandit — marked a change for fans young and old of the show.

“The Sign,” which released on April 14, clocks in at a solid 28-minute runtime, providing audiences with an extra-long season finale to say goodbye for now to the Heeler family.

The final installment of season three follows the wedding of Radley, Bandit’s older brother, and Frisky, Bluey’s godmother. What starts as a picture-perfect gathering of friends, family and a gaggle of excited flower girls dissolves into a chaos when a runaway bride disrupts the planning.

But Frisky’s cold feet isn’t the only thing the Heeler family has to worry about. The previous episode, “Ghostbasket,” revealed that the family is in the process of selling their beloved home as they prepare to move to a new city thanks to Bandit’s new job opportunity.

And Bluey is not happy about it.

From breakdowns of howling puppies during school to desperate attempts to rip the large “For Sale” sign from the front lawn, Bluey is ready to try anything to keep her family in their home of Brisbane, Australia.

The extra-long, extra-emotional episode follows the hijinks of Chilli, Bluey, Bingo and their cousins Muffin and Socks, as they race across town to track down Frisky and restore order to the impending nuptials. But Bluey’s ulterior motives — and Chilli and Bandit’s own doubts about uprooting their family — provide just as much chaos.

And as juvenile as that might all sound — because after all, it is an animated children’s show about anthropomorphic dogs — “The Sign” is about much more than just the silly adventures of a young girl and her family.

In true “Bluey” fashion, the episode doesn’t shy away from the hard stuff. Bluey and Bingo’s confusion and hurt about their upcoming move isn’t dumbed down for younger audiences. The sisters are shown experiencing raw and big emotions in an honest way. It affirms for children that it’s okay to feel, and for parents, that their kids understand more about the big world around them than they probably think.

But the youngest members of the Heeler family aren’t the only ones given the grace to work through the scary parts of life. As Bluey and Bingo grapple with the uncertainty of change, Bandit and Chilli stress about making choices that could hurt their family.

One moment in the episode finds the Heeler parents staring up at the large ‘For Sale’ sign in front of their family home, a “SOLD” sticker in bright yellow slapped across it. Bandit’s face droops as he lets out a sad sigh.

“I just wanna give them the best life I can,” he tells Chilli.

As the Heeler family grows to learn throughout their extra-long runtime, change is a scary thing. Whether you’re a 7-year-old afraid of leaving behind the only world you’ve ever known or a parent trying your best to give your child an even bigger one, “The Sign” is a reminder of how scary the unknown can be.

Nothing in life is certain. There’s no way to know if the choices we make will be a success or a failure, whether they’ll enable us to thrive or prove difficult to survive through. And while change, no matter how big or small, can be scary, it can also be quite beautiful.

Throughout “The Sign,” the Heeler family learns perhaps one of the most valuable lessons life has to offer. As Bluey shares with her friends that she may soon move to a new city and “never see any of them ever again,” her always-wise teacher, Calypso, shares a secret with her:

“Everything will work out the way it’s supposed to, Bluey.”

Because “The Sign” is not just about the physical one sitting in the Heelers’ front yard. It’s also about the ones that follow them throughout the day, from Bingo’s favorite butterfly to Bluey’s lucky coin. Life is made up of the small things and the bright moments that guide us throughout the day.

So while fans may be temporarily bidding goodbye to the Heelers, “The Sign” was the perfect send-off. And while there will indeed be a season four of “Bluey,” only time will tell what adventures everyone’s favorite canine family will get up to next.

After all, as Chilli says, “I guess we’ll see.”
