For the active outdoor family, the Sussex Spaniel can be a great companion, keeping in mind the spaniel traits of collecting, carrying and holding found items. They may be better with older children who can follow rules not to leave precious treasures lying around. With those who enjoy a good long romp in the countryside at a steady pace, the Sussex will be a fine friend.
While many dogs are traditionally thought of as being good with children, all dogs and children need to be taught to get on with each other and be safe together. Even so, dogs and young children should never be left alone together and adults should supervise all interactions between them.
