This tube carriage at Mile End station in London was packed with labradors training to be guide dogs.

Ryan, who filmed the video on March 29, couldn't believe his eyes when he saw 10 labrador pups on his tube carriage: "I stayed on the train as I wanted to see how they were and just to take it all in, Labradors are my favourite in the world so when am I getting this opportunity again?"

The filmer added: "I got into work late, but who cares when you have memories like that? They actually came in two sets of five so I couldn’t believe it, it was like a conveyor belt of dogs arriving."

According to Ryan: "A few of the dogs actually were misbehaving and playing with each other, but they’re only pups in training so they’re allowed to be."

Getting on the wrong/right tube and finding 10 Labrador pups out doing some training as they become guide dogs. They were wonderful. It was taken at Mile End station at about 10.30am today.

So I had the option of going to work or going with the dogs, we know what won. I stayed on the train as I wanted to see how they were and just to take it all in, labs are my favourite in the world so when am I getting this opportunity again?

I got into work late but who cares when you have memories like that. They actually came in two sets of five so I couldn’t believe it, it was like a conveyor belt of dogs arriving.

A few of the dogs actually were misbehaving and playing with each other but they’re only pups in training so they’re allowed to be. But all in all, they were placid and good boys/girls. Most of the tube was taking pictures apart from one guy in the video who wasn’t impressed.
