This was the adorable moment a Rottweiler was the best man for his owner's wedding - after the groom met his wife-to-be at a dog rescue centre.

Christopher McCarron, 69, tied the knot with fiancee Margaret Allison, 56, on June 19 in a civil ceremony Motherwell, North Lanarkshire.

And unusually, his best man was a different kind of friend - a rescue dog who Chris says ‘rescued’ him.

Well-behaved Jack sat quietly through the short ceremony, wearing a mini tuxedo attached to his collar, while Chris held his lead.

And the pooch even sneezed when Chris said 'I do'.

Chris adopted the Rottweiler, named Jack, after the death of his son, Chris Jnr, who died three years ago aged 43.

In the wake of his son’s death, Chris sold his business and got a divorce.

He hoped that getting a dog might help him recover from his grief, and was immediately won over by Jack, who had been at the Dog’s Trust centre in West Calder for nine months.

And in a sweet twist of fate, Chris met his new love, Margaret, while out walking Jack at the rescue centre - and promised to keep her updated on his pet’s progress.

Romance blossomed and the newlyweds now consider Jack, aged around six years old, to be a part of their family.

Chris said: “We had a lovely sentimental day, and Jack played a big part.

“He loved it, he really did. I wouldn’t have considered getting a rescue dog because of his age - he’s around six.

“But when he went up to me, we just clicked. Little did I know that I’d meet my future wife at the rescue centre too.

“I don’t believe that I rescued Jack - I think he rescued me.

“When we decided to get married, Jack had to be there.”

Glasgow Times: Jack certainly scrubbed up well, wearing a mini tuxedo around his neck for the big day.Jack certainly scrubbed up well, wearing a mini tuxedo around his neck for the big day.

Margaret, a care home worker, had been initially looking to rescue a small dog at the rehoming centre but did not find anything suitable.

But when she met Chris they bonded over their shared love of dogs - and have seen Jack’s character transformed since he has lived in a loving home.

Jack spent most of his life as a guard dog, cooped up in a kennel, and Chris was warned that he should not be allowed to play with other dogs when he adopted Jack in 2015.

But both Chris and Margaret believe that Rottweilers have an unfairly got a bad reputation as a breed, and should be given a chance.

Margaret said: “When Chris said ‘I do’, Jack sneezed, as if to say ‘I do too’.

“He was a star - he posed for all the pictures.

“The registrar said it was the first time he’d seen a dog being the best man.

“We did think about Jack carrying a cushion with a ring.

“He had his wee tuxedo on but he went in the garden and got a bit mucky.”

Both Chris and Margaret are divorcees and live in Motherwell, North Lanarkshire.

Chris has three children as well as his late son, Chris Jnr, and five grandchildren.

Margaret has three children and four grandchildren.

The ceremony was very small with 15 guests including staff from the Dog’s Trust, and the couple went out for a meal in the evening to celebrate.

Chris added: “This is our family now, me Margaret and Jack.”
