BBC Radio 1 presenter Greg James was left horrified after his dog Barney did a huge wee on the train in front of shocked commuters.
The 38-year-old was taking the train from London Waterloo to the vets for Barney to have an operation on his knee due to the dog struggling with arthritis.
The journey was going as normal until Barney shuffled near to the door and started to go to the toilet, as reported by Need To Know.

This left his owner Greg in absolute shock – who stated it was the biggest “p***” he had ever seen.
Trying to clean up the mess, the radio star rushed to the toilet to get some tissues, however with the pair needing to get off at the next stop, he was forced to leave the patch of wee.
After they got off the train heading to Portsmouth, Greg approached the guard to apologise.
The presenter also later apologised to South Western Railway and any passengers who saw what happened.
In a video, Greg asks viewers what they feel he was supposed to do in this situation.
“He loves the train, we’ve had a load of journeys together,” he said about Barney.
“He was all round being a very very good boy…. until – he shuffles over to the door and does the biggest p*** I’ve ever seen.
“And I panic, I freeze.
“What are you supposed to do in this situation?
“I’m not exaggerating when I tell you, it was two minutes of p***.”
Greg was contacted by South Western Railway who assured him all was well on their end.
Charlie, who is head of train presentation said: “Please don’t feel bad!
“Canine companions like Barney will always be welcome on South Western Railway, even when their journeys don’t go entirely to plan.
“We hope his op goes well and he’ll be back on his feet in no time.
“If you are interested in finding out how the team and I deal with worse than this on a regular basis, especially after a big Friday night out, I would be thrilled to show you how we keep our trains clean and tidy for customers every day.”
