WATCH | Longford boy goes viral with priceless reaction to getting a new puppy for his birthday

Longford boy, Tyler Robinson, and his new puppy, Tails, have gone viral following an adorable video uploaded by Tyler's mum Hazel.

Hazel tricked her son into believing he was getting dog toys, poop bags and puppy pads for his birthday, confusing Tyler as he pulls the various items out of a bag, all while an impatient squeaking can be heard in the background.

In a social media post, Hazel said that Tyler has been having "a littler bit of a hard time" at school.

"He's had an assessment and it waiting on a few more. He is having trouble socialising, severe dyslexia, along with a few other issues we are working on," she said.

"I thought he deserved a treat as he’s been trying so hard, so here’s Tails the newest member of our house."

Tyler's reaction is priceless when he opens up a box and cute little tails pops out. Scroll back up to see for yourself.
