Meet Tan, the border collie, who's learning to be a sheep dog.
Tan works for @HerdyShepherd1, the tweeting sheep farmer in Cumbria whose beautiful landscapes, shots of his flock and snaps of his working dog Floss have been a ray of sunshine for the last few months.
It gets pretty cold up there.
But that doesn't daunt Tan - he's learning the ropes. Watching the hungry sheep.
He has "cockerel-chasing adventures".
Tan's learning how to be the best sheep dog he can be.
At least Floss is around to give some advice. It's not his mum BTW, they may even mate one day. #Awkward.
Sheepdogs have long workings lives - Herdy's last dog died aged 11, but they can start as early as six months.
