A wheelchair-bound golden retriever dives head-first into a swimming pool as he refuses to let old age spoil his fun.

Eleven-year-old Lion, from Armação dos Búzios, Rio de Janeiro, Brazil, was determined to join his sister Taiia for a dip in the infinity pool.

Footage shows the playful pooch head towards the pool with his tongue wagging and wheels dragging behind him.

Suddenly his owner, Katia Luz DePlachett, scrambles after Lion after noticing him making his way over to the pool.

The video shows Lion crash into a sun lounger before plunging head-first into the turquoise water.

Lion shows off his best doggy paddle causing him to break away from his wheelchair.

Katia posted the clip to the 113,000 followers of Lion and Taiia’s everyday antics, with the video receiving more than 4,000 likes after it was posted on January 21.

According to a GoFundMe page for Lion, his cancer has unfortunately returned but his owners are determined to give him the best end to his life.

In October, Lion was diagnosed again with mastosytoma cancer after an abscess was found in his leg.

Lion, who was adopted aged seven, is undergoing chemotherapy treatment and the wheelchair allows him to still visit his favourite parks.

A birthday post in the words of Lion was posted yesterday on the GoFundMePage: ‘As most of you know, two years ago I was diagnosed with cancer.

‘My parents, with generous help from all of our friends, paid for my surgery, treatments, and chemotherapy to give me two more glorious years of the wonderful life that I love.

‘Now the cancer has come back and I may not have the energy and youth to fight it.

‘Therefore my parents have given me permission to live badly and to have as much fun as I possibly can in the time I have left.’

In an effort to let Lion enjoy life to the full, his owners have allowed him to swim in the pool when he wants, eat rich food, have belly scratches on demand and sleep in the comfiest of beds.
