I'm worried about the horse. Is it okay for them to carry that much?

IKR I know the horse isn't real but it still bothered me how they made it carry 2 trunks and 2 people.

Riiight??? I really can't accept it, i would love to if they have 2 horse 1 for carrying their things and 1 is for them if they don't want to be separated. Like really aaaaahhhhh it bothers me that much. Horsey you deserve better treatment ಥ_ಥ
