A woman turned a drive thru into a drive MOO after taking her one ton cow for a sweet treat.

Kelly Landry and her huge Holstein Magnum like to take regular trips to the Tim Horton’s in Lake Sylvan, Alberta, Canada, and November 20 was no different.

Funny footage shows the black and white horned animal pausing to take a look at the menu before heading to the server window.

Having been served, Kelly gave Magnum his favourite snack, Timbits – mini doughnuts – which he tried to scoff directly from the box before they had been put on the ground.

Kelly said: “I like to go to Tim Hortons. Many people do it with horses but that's too common.

"It's just to have some social time and people love to see it. They took pictures with him, asked me questions and I had some nice, long chats.”

Kelly bought Magnum eight years ago with the intention of harvesting him for meat, but grew too attached after realising how sweet he was.

Kelly said: "He would come to see me and 'moo' at me as well as running around the barn and call for me.

"I thought he could do as much as a horse, so I started training him. He was happy and jumping and following me everywhere.

"So I decided to put a saddle on him and give it a try. And here I am."
