Zach Braff is every inch the doting fur parent as he plays fetch with his rescue dog Billie

He has numerous projects in the works, but Zach Braff enjoyed a day off to spend some quality time with his best friend, his dog Billie. 

The Scrubs actor, 46, was spotted at a dog park in Pasadena over the weekend, playing fetch with the enthusiastic rescue dog.

Working a sporty look, Zach looked ready to break a sweat wearing navy blue shorts, white Nike leggings and orange and grey trainers.

Man’s best friend: Zach Braff enjoyed a day off from his bustling career to spend some quality time with his best friend, his pooch Billie, at a Pasadena dog park over the weekend 

Allowing his dog to roam freely, he placed his pooch’s leash around his shoulders.

The actor was every inch the proud fur parent as he played fetch with his dog using an orange tennis ball launcher.

Billie looked as happy as can be enjoying a day in the sunshine with her owner.

As Billie played with the other pooches, Zach caught up with a fellow park attendee.

The actor sat on the picnic table as he chatted with the young woman, who also looked ready to workout in lilac leggings and trainers.

Seems as though a day of fresh air was exactly what the busy actor needed.

On top of his showbiz career, Zach is also in a relationship with actress Florence Pugh, 25, who has been busy promoting her upcoming spy thriller Black Widow.

The couple have been going strong for over two years, despite vocal critics of their 20-year age gap.

Florence recently gushed about her beau in a heart-melting birthday tribute which included snaps of their rescue dog Billie.

‘It’s this magical persons birthday. A year ago we got Billie three days before Zach’s day and she’s flopped on her back for tummy tickles from him like this ever since. A special day for a special fella requires special foot wear and fluffy trackies.. obvi,’ she captioned the post.

‘His need to make people laugh and smile is never ending, his constant generosity and love for others is infectious, his creativity and ability to put real and honest words onto the page inspires many and all who’s around him, but above all.. his appreciation for life and excitement for LIVING is something I always take note of. Happy Birthday chicken, odd shoes is a good look.’

Last June, Florence addressed the couple’s 21-year age gap, in an interview with ELLE UK.

‘I have the right to hang out and be with and go out with anyone I want to,’ she asserted. ‘I’ve always found this part of what people do really bizarre.

‘I’m an actor because I like acting and I don’t mind people watching my stuff, but people have no right to educate me on my private life.

‘I know that part of being in the spotlight is that people might invade your privacy and have opinions on it, but it’s bizarre that normal folk are allowed to display such hate and opinions on a part of my life that I’m not putting out there.

‘It’s a strange side of fame that you’re allowed to be torn apart by thousands of people even though you didn’t put that piece of you out there.

‘My point to all this is that isn’t it odd that a stranger can totally tear apart someone’s relationship and it’s allowed?’

Meanwhile, Zach has remained busy with roles in the upcoming films Shriver, Cheaper By The Dozen and the thriller Tiburon.
