The show is - broadly speaking - great. Main characterisation of each is well developed over the 2 completed series so far. However, I do wonder why the horses in the third series episode 1 appear to be and obviously are distressed?

In episode 1 a horse is harnessed to a cart and standing outside a farm house where Geralt, Ciri and Yennifer are currently staying. They are being pursued - naturally by evil people seeking to gain control over Ciri and her powers? But a harnessed horse is standing on set in the snow and pawing the ground in 2 separate scenes? I'm only 32 minutes in! Why is this so?

Any explanation would be appreciated please? I cannot abide animal cruelty or distress in any form.
