A Dying Breed (S03E08)

The vets explore a high-tech dairy farm, pondering the impact of its cold efficiency. Meanwhile, Miss Westerman returns with her dog Hamish, and Tristan tries to steer clear of her, haunted by the memory of losing her pet during its last visit. Concerned about rumors that all dogs might be put down if war breaks out, she finds reassurance from Tristan. The vets agree to spay a cat for a low fee, only to realize they might have taken on more than they expected. Siegfried treats Herbie Hinchcliffe's elderly horse, Dolly, and finds himself emotionally invested in her care as he faces the difficult decision to put her down.
