The internet is all aboard the puppy train this week after images of an 80-year-old man who built a makeshift dog train have begun to gain traction.
Texas man Eugene Bostick, a retired farmer turned conductor of Fort Worth's "dog train", began taking in stray dogs at his farm after retiring 15 years ago, The Dodo reports.
They say you can't teach an old dog new tricks, but Mr Bostick has managed to change careers by making the tractor-pulled carriages made from plastic barrels.
He says the rescue dogs have a lot of room to run around on his farm, but he thought it would be nice to take the nine dogs currently in his care on little outings.
"One day I was out and I saw this guy with a tractor who attached these carts to pull rocks. I thought, 'Dang, that would do for a dog train'," Mr Bostick said.
A "pretty good welder", he cut holes in the barrels, put wheels under them and tied the carriages together.
A couple of times a week, the public can see Mr Bostick and his canine train trucking along the quiet streets, through the forest near the farm or a local creek.
It's something the dogs always get excited about, he says.
"Whenever they hear me hooking the tractor up to it, man, they get so excited. They all come running and jump in on their own. They're ready to go."
Mr Bostick's dog train isn't new, with news stories about him last year, but the internet's ever-shifting focus has been trained on it since a Facebook post last week was shared more than 50,000 times.
