The Channel 5 show, which stars Nicholas Ralph, Rachel Shenton and Samuel West, aired its third episode of series three and saw Samuel's character, Siegfried Farnon, come across a young racehorse named River who was in need of care.

But while the vet is pleased to be in the company of the animal, River's declining health poses a dilemma for Siegfried on whether he can keep the horse alive. His time with the horse also triggers memories of his time working in the Army Veterinary Corp during the First World War.
It seems the moving storyline in the episode proved to be highly emotional for those watching at home. One person wrote on Twitter: "To the writers of @AllCreaturesTV I'm in pieces now but beautiful, beautiful episode. Thank you for the best piece of TV all week #AllCreaturesGreatandSmall #ACGAS."

The show is often praised for its light and dark storylines between the adored characters and it seems series three has more "tough" moments ahead. Rachel Shenton, who plays Helen Alderson, told Radio Times: "There are real heartfelt moments that happen between James and Helen that only happen when they're in the bedsitter on their own.
"And as the season progresses there are some things that are really tough for them to discuss and make them both feel really vulnerable. Being able to do that in their own environment in the bedsitter sort of peeled off another layer, I think."
